Chocolate Fudge Peanut Butter Cake

Chocolatey gooey desserts are one of the simplest joys. They’re the type of dessert that makes you feel all cozy on the inside. So what could make this better? Peanut butter of course! The rich savoriness of the peanut butter perfectly complements the deep, well, chocolatiness, of the chocolate. This would be reason enough to make these, but it was also the perfect birthday cake for my roommate Ethan, who loves this peanut butter and chocolate combination more than anyone I know.

The cake is made of almost entirely chocolate, which is melted with butter in the microwave. This melted chocolate is mixed together with eggs, vanilla, just a bit of sugar… and that’s it! In addition to being super quick and simple to make, this batter is also constructed for maximum fudginess: it’s almost all chocolate, and there’s no flour.

Building these mini cakes is also easy. Butter a muffin tin and dust with cocoa powder. Then, fill each about a quarter of the way with the batter, add a spoonful of peanut butter, and cover with more batter to reach about 3/4 of the way up.


Then, bake these little pieces of fudgy heaven, but not for too long! The gooey center that’s the goal of this is of course dependent on these cakes being taken out as soon as they’re done. Then, dust with powdered sugar, and get ready to lick your lips and be reminded of happy things.


If extra-moist cake was the only type of dessert ever discovered by humans, I’d still be happy. And, they make a great birthday gift.
