It’s no secret that I love peanut butter and chocolate together. Give me a bag of Justin’s milk chocolate peanut butter cups and I’ll happily call it a day. Pair a dark chocolate cake with a fluffy cap of salted peanut butter frosting and I’ll be set for the whole weekend. To that end, today’s recipe is an update of an old classic, an eggless chocolate cake made with buttermilk and just two gluten-free flours. I adapted it long ago from the Fannie Farmer cookbook and recently revisited it because it is such a classic: a tender crumb, quick to whip together, and now incorporates natural sweeteners.

You should always have a one-bowl cake or two in your recipe arsenal and this one, for a simple chocolate cake with or without frosting, fits the bill perfectly. Sometimes you just need a chocolate cake — because it’s your birthday, because it’s Saturday, because you need a slice of something sweet to go with your afternoon cuppa, because you have that bit of buttermilk in the fridge that needed to be used yesterday.

In this recipe I combined oat and sweet white rice flours and swapped out the granulated sugar in the original recipe for maple sugar. This is a slightly dense cake, as the buttermilk replaces eggs so it’s not as soft as some. The frosting is a lovely mix of butter and peanut butter sweetened with homemade coconut powdered sugar with a good amount of salt to balance and bring out the flavor. I recommend letting it come to room temperature before serving for the best-tasting crumb.

You could also serve this plain, with a little whipped cream or ice cream. This unassuming gem comes together in a snap; enjoy.

Need substitutions? Swap tapioca for the sweet rice flour and sorghum flour for the oat flour. starch. Try coconut sugar in place of the maple sugar or just use brown sugar. For the frosting, use regular powdered sugar for the powdered coconut sugar.

To make the cake dairy-free: mix one cup coconut milk with 1 tablespoon vinegar, let stand for 15 minutes, and use in place of the buttermilk.
