The very best potluck dessert: simple, vegan, gluten-free — and totally delicious!

What’s more disheartening than baking your very favorite potluck dessert, then having maybe half the crowd say, “No thanks, not for me”?

You’ll probably hear “Sorry, I’ve gone gluten-free.” Or “Does that have tree nuts? I have to be careful.” Or “We’re dealing with allergies in our house, so we eat dairy-free and egg-free.” Or the very succinct (yet all-encompassing) “I’m a vegan” — which means no eggs; no milk; no butter or yogurt or cream cheese or heavy cream or… well, so many of the ingredients that go into the typical dessert.

What’s a passionate and eager-to-please baker to do?

Find a one-size-fits-all-diets dessert, and stick with it!

The perfect potluck dessert is not only amenable to a range of dietary concerns, it’s easy to make. It includes everyday ingredients — nothing requiring a special trip to the supermarket (save perhaps the one thing you should always have on hand when baking for potlucks: 1:1 gluten-free flour).

It’s also easy to dress up or down, seamlessly morphing from progressive dinner party finale to refreshments after the swim meet.

And bottom line, it’s a standout on the buffet table. Not just “This is pretty good considering it’s gluten-free and vegan.” But “This is REALLY GOOD.”

Step right up, oh most venerable of quick-and-easy, delicious desserts: Cake Pan Cake.

What goes around comes around: this cake has a long history. Sometimes known as “war cake,” it uses neither butter, milk, nor eggs — all of which were rationed (and thus hard to get) during World War II.

We’ve also seen this moist, dark chocolate cake referred to as Wacky Cake — presumably because preparing it doesn’t require even a bowl: you can stir together all of the ingredients right in its baking pan.

Here at King Arthur we call this recipe Cake Pan Cake — again, because it can be stirred together in the pan (though it’s easier and more effective to simply stir everything up in a bowl, if you don’t mind cleaning a single bowl).

It’s been around so long, and is so beloved by generations of fans, we named it our Recipe of the Centuries in honor of our 225th anniversary back in 2015.

Thus a cake whose original provenance is in wartime deprivation returns to the limelight as the potluck dessert everyone can enjoy — special diet or not. How neat is that?

Watch how this is done — honestly, it couldn’t be easier.

Here’s the flour that turns this cake (and cookies, pancakes, quick breads, pie crust, biscuits, scones…) from gluten-full to gluten-free: our Gluten-Free Measure for Measure Flour.

Measure for Measure is a simple 1:1 substitute for all-purpose flour in most of your favorite recipes (all except those using yeast). No adjusting liquids, adding xanthan gum, or mixing starches; just use Measure for Measure in place of all-purpose flour and you’re good to go.

What’s more, no one will know you’ve made the swap; your baked goods will taste just as good as they always do. That’s why this flour should be in every baker’s pantry; when you’re not sure which of your guests, friends, or extended family members are eating gluten-free, play it safe: opt for Measure for Measure flour.

The best potluck dessert: Cake Pan Cake

Preheat your oven to 350°F. Lightly grease a 9″ round cake pan.

Put all of the following in a mixing bowl:

1 1/2 cups (6 1/4 ounces) Gluten-Free Measure for Measure Flour
1 cup granulated sugar*
1/4 cup Dutch-process cocoa or natural cocoa
1/2 teaspoon salt
1 teaspoon baking soda
1 teaspoon vanilla extract, gluten-free if necessary
1 tablespoon vinegar, cider or white
1/3 cup vegetable oil
1 cup cold water or cold brewed coffee

*Strict vegans won’t use regular granulated sugar due to the way it’s processed. If you’re concerned about the source of your granulated sugar, find one that’s labeled vegan; many organic sugars are vegan, and will say so on the package.

Whisk everything together

Want to use a stand mixer or electric beater? Go right ahead.

Potluck dessert via @kingarthurflour

Scrape the bottom and sides of the bowl, and whisk or beat again to recombine any sticky residue. Whisk or beat until smooth, with perhaps just a scattered few small lumps.Potluck dessert via @kingarthurflour

Pour the batter into the prepared pan.

Potluck dessert via @kingarthurflourBake it

Bake the cake for about 30 minutes, until a toothpick inserted into the center comes out clean, or with a few moist crumbs clinging to it.

Place the pan on a rack, and let the cake cool right in the pan.

While the cake is cooling, consider your icing options.

Choose your icing

Honestly, making dairy-free icing is potentially more of a challenge than making a vegan, gluten-free cake! Lots of the structure of a simple confectioners’ sugar icing comes from butter, milk, cream, vegetable shortening, cream cheese, or even nut butter. (While vegetable shortening isn’t an allergen, we know many of you avoid it; so we’ve chosen not to use it here.)

Minus those traditional icing ingredients, you have to be quite precise with the liquid/sugar balance. You want to make icing that’s the perfect texture: thin enough to spread easily, but not so thin it runs and pools at the edges of the cake.

So what are our options?

Initially I thought I’d do a dairy-free riff on the suggested frosting accompanying the Cake Pan Cake recipe: chocolate chips melted with half & half. But then I discovered that most chocolate chips aren’t dairy-free.

Just like Neapolitan ice cream: berry, vanilla (or coffee), and chocolate.

So I worked up three variations on a basic confectioners’ sugar icing.

Each of the following makes about 1 1/2 cups icing, enough to generously frost a single-layer 9″ round cake.

3 cups (12 ounces) confectioners’ sugar
3/4 cup (9 ounces) raspberry jam or preserves
1/8 teaspoon salt
1 teaspoon vanilla extract

Stir everything together. If the frosting is too stiff to spread, add more jam; if it’s too thin, add more sugar.

Experiment with different flavors of jam or preserves; you don’t want a spread that’s TOO chunky and stiff, but small seeds (e.g. raspberry) and pieces of fruit are fine. IMO, apricot and cherry both pair well with chocolate.

The texture of this icing looks just about right. It follows the spatula around the bowl, but gradually settles once you stop stirring.

Vanilla or coffee
5 cups (20 ounces) confectioners’ sugar
5 to 6 tablespoons (2 1/2 to 3 ounces) water or cold brewed coffee, or enough to make a smooth frosting
1/4 teaspoon salt
2 teaspoons vanilla extract

Stir everything together, starting with the lesser amount of liquid. Let the frosting sit for 5 minutes. If it’s too stiff to spread, add more water or coffee; if it’s too thin, add more sugar.

Should you still add the vanilla if you’re using coffee? Absolutely! Vanilla makes everything taste better.

Chocolate fudge
2 1/2 cups (10 ounces) confectioners’ sugar
1 cup (3 ounces) unsweetened cocoa powder, natural or Dutch-process
about 6 tablespoons (3 ounces) water or cold brewed coffee
1/8 teaspoon salt
1 teaspoon vanilla extract

Stir everything together. Adjust the frosting’s consistency with additional water/coffee or sugar, as needed.

Here I’ve frosted the cake with vanilla icing and garnished it with a bit of leftover chocolate icing. In the absence of chocolate icing, an easy garnish is a drizzle of dairy-free chocolate syrup.

Ice your cake

Pour/spread the icing atop your cake. Be aware that gluten-free cake tends to be a bit more fragile than standard cake; if your icing is too stiff to spread easily, thin it with liquid, a few drops at a time, until it spreads readily.

OK, this cake is ideal for the aforementioned progressive dinner party. But something more casual is needed for those hungry kids at the swim meet.

Best potluck dessert for kids: cupcakes!

Most kids can’t resist cupcakes, and thankfully they’re easy to make. Simply portion your prepared cake batter into a paper-lined muffin pan; a muffin scoop makes the task easy.

Bake the cupcakes in a preheated 375°F oven for about 22 minutes, until a toothpick inserted into the center of one comes out clean. I didn’t test mini cupcakes, but my educated guess would be to bake them for about 10 to 12 minutes.

Remove the cupcakes from the oven, and transfer them to a rack to cool. Again, gluten-free cupcakes can be fragile; let them cool in the pan for at least 5 minutes before you attempt to move them.

Ice and decorate

Plain vanilla icing is a good choice here; no sense torturing kids with flavors they may not like, and vanilla is a blank slate for all kinds of garnishing, like colorful sugars or more of that chocolate syrup.

You’ll need about 3/4 cup of icing for a dozen cupcakes; so make a half-recipe of the vanilla icing above (or of any of the three icings listed).

Oh, and if you’re wondering about the fancier individual-serve cakes pictured near the top of this post — they’re easy! Simply bake your cake in a 9″ round pan, frost as desired, then use a 2 1/2″ biscuit cutter to cut it into elegant single servings. (Share the scraps with the kids!)

Next time you need a potluck dessert —

Nut-free, gluten-free, dairy-free, egg-free? Bring those diets on! You can’t go wrong with Cake Pan Cake made with Measure for Measure flour.

Since icing was my biggest challenge here, do you have a favorite vegan/gluten-free icing recipe? We’d love to hear about it — please comment below.

    1. The Baker's Hotline

      Hi Zeina! Depending on the size of your appetites, this cake can be cut 3 x 3 for nine large servings, or be cut 4 x 4 to make 16 smaller servings. Because this cake is so moist, it may be difficult to slice into layers. If you’re going to try, we’d recommend putting the cake in the freezer for a couple of hours to give it a firmer, more stable texture before attempting to carefully slice layers from it with a serrated knife. To keep things simple (and extra delicious) we’d recommend using 2 9″ square pans and making a double batch. The 9″ size will make each cake a bit shorter than it would be in an 8″ cake, and you can use each full cake as a wonderfully decedent layer. Happy baking! Annabelle@KAF

  1. Darleen

    Can this cake be made not chocolate? By using 1 3/4 cup GFM4M Flour and vanilla or lemon or orange or Almond ….. flavoring? 🙂

    1. The Baker's Hotline

      Hi Darleen, we actually have a vanilla version of this cake that was posted in the Baking Sheet, our old publication, many years ago. We’ve thought about posting it on our website to share, but our taste testers found the vanilla version to be just a bit more underwhelming than we’d hope. If you’re okay with a cake that’s slightly less moist, you’re welcome to give this recipe a try. (It will still give you better results than trying to make this chocolate version a vanilla cake.) Find vanilla versions as well as coconut using this link here. our Measure for Measure Flour to replace the all-purpose flour in the recipe. Happy GF baking! Kye@KAF

  2. Dixie

    Just made cupcakes according to the recipe (and using the KAF m-for-m GF flour). Each cupcake has a little dimple in the middle of its top — that part never rose (as opposed to rising and then falling). Thoughts for next time? The cupcakes are done through.

    1. The Baker's Hotline

      Hmm, perhaps the outer crust set up in certain places before the rest of the batter rose. Try lowering your oven temperature by 25°F and increasing the baking time by 4 minutes or so, until a toothpick comes out clean or the internal temperature of the cupcake reads 210°F. Annabelle@KAF

    2. Dixie

      Hm, just made another 2 dozen with a lower temp. Definitely baked through. But the same thing happened again. They sure are delicious, though!

  3. Marianne Juhl

    I am going to try this recipe as I have a gran daughter that is vegan and I will pass it on to her and I will bake it for her (surprise package).
    Love your recipes, some of them I am not able to do.

  4. Denita

    This cake is a stunning standard. Thanks for reminding me about this recipe. Turns out great every time.

    Curious about the vanilla/coffee icing. 5 cups of confectioners sugar? I cut it back to 2.5 cups and used the same amount of liquid, with a beautiful result. 5 cups of the sugar would have easily needed 2x the amount of liquid. Unless I was doing something wrong.

    1. The Baker's Hotline

      We’re so glad this cake is a hit in your kitchen, Denita! We found that when measuring the powdered sugar by weight, the ratio worked great. When measuring by volume, powdered sugar tends to be uncooperative and packs itself into the cup, giving you way more than you needed, (That pesky sugar!) Thank you for bringing this up so we could make an amendment to the recipe. We’re so glad you enjoyed it! Annabelle@KAF

  5. Mr. Ware, vegan baker

    This recipe is called vegan, yet it uses granulated sugar. Granulated sugar is not a vegan product. It is a highly refined substance. Vegans use natural, unrefined, or least processed sweeteners. As far as I know, granulated sugar is still filtered through activated carbon which can contain charred animal bones – not a vegan process by any means. A truly vegan dessert would use raw cane syrup or another, typically liquid alternative to granulated sugar, excluding honey. I am not posting this comment to create an argument or insult anyone. Its purpose is strictly one of clarification.

    1. Sam

      Vegan granulated sugar is available at many grocery stores and labeled as such, e.g. Whole Foods store brand.
