Vegan chocolate cupcakes with peanut butter buttercream

April 5, 2025

   

After a couple of underwhelming bakes with my decades-old metal cupcake tray, I put "silicon cupcake tray" on my op-shopping wishlist. I easily tracked one down for a couple of dollars within weeks and then, of course, I had to test it out. I browsed my old recipe bookmarks and picked out a Burned Butter post for chocolate-peanut butter cupcakes.

The tray had only six cups, so I halved the recipe... and still ended up with 10 cupcakes. (If I'd read the source recipe properly, I'd have known that the original was supposed to make 24. I've written out my 10-cupcake version below.) The cake itself is a lovely, simple pantry-friendly vegan chocolate. The only potential pitfall is getting the batter mixed properly - I sifted the dry ingredients directly into the wet ones and ended up with a few powdery lumps in the cakes. I pulled the cakes out at the 20 minute mark to keep them moist, but found that their bottoms dragged on every surface they touched, leaving cakey smears on the baking tray, the cooling rack and the lunchbox I stored them in. The latter four had more time to rest in the tray and fared better.

My veganised buttercream went off without a hitch, and I slathered on a modest amount with a knife - I have a minimal-frills attitude to cupcakes, and these were bang on my preference. The silicon pan showed much promise, and I scavenged a second six-cupper from another op-shop a month or so later.

chocolate cake

1 1/8 cups plain flour

1 cup caster sugar

1/2 cup cocoa powder

1 teaspoon bicarbonate of soda

1/4 teaspoon salt

1/3 cup neutral vegetable oil

2 teaspoons vanilla

1 teaspoon white vinegar

1 cup water

peanut butter buttercream

1/2 cup smooth peanut butter

1/3 cup margarine

1/2 teaspoon vanilla

1/2 cup icing sugar

Preheat an oven to 180°C. Prepare a cupcake tray as you wish, with papers and/or oil.

In a medium bowl, sift together and flour, sugar, cocoa, bicarb soda and salt, then stir to combine.

In a small bowl, whisk together oil, vanilla, vinegar and water. Gradually pour the wet mixture into the dry mixture, stirring thoroughly to combine; the batter will be quite liquid. Gently pour the batter into the cupcake tray until two-thirds full. Bake for 20-25 minutes, until the cakes pass the skewer test. Allow them to cool before icing.

Beat together the peanut butter, margarine and vanilla. Sift over the icing sugar and beat until well combined and fluffy. Spread the buttercream over the cooled cupcakes.
