Mug cakes, man. I resisted them for a long, long time. Because – yup – just as I suspected, they are way WAY too easy to make. And consume. Possibly daily.

Totally divine with or without the chocolate toppers.

I adapted my recipe from this one on Kirbie Cravings, swapping out the dairy milk for almond milk and replacing the sugar with pure maple syrup. The biggest change I made was to halve the recipe – I found that this version produces just enough mug cake to satisfy my sweet tooth without going totally overboard.

It fits perfectly into my Fiestaware teacups, so I actually like to call it “teacup cake.” Except this cake is not dainty, my friends. Especially with a bit of chocolate sprinkled on top. It’s actually kind of pure grubbin’.

Easy Vegan Peanut Butter Mug Cake

You’re 3 minutes away from sweet tooth attack to moist, rich cake in your hot little hands. I affectionately call this “teacup cake” because it’s a petite version that makes just enough to satisfy my sweet tooth.

Ingredients:

  • 2 tablespoons white whole wheat flour or all-purpose flour (sub your favorite gluten-free flour blend for a GF version)
  • 2 tablespoons peanut butter (I use all-natural creamy peanut butter)
  • 2 tablespoons unsweetened almond milk (could substitute dairy milk for non-vegan version)
  • 1 tablespoon pure maple syrup (could substitute granulated sugar, brown sugar, or honey for non-vegan version)
  • 1/4 teaspoon baking powder
  • 1/2 teaspoon pure vanilla extract (optional)
  • Chocolate chips or chocolate chunks for topping (I use these dairy-free chocolate chips)

Directions:

  1. Add all ingredients except the chocolate chips (if using) to an 8-ounce or larger microwave-safe mug. Use a fork to stir together until combined. It might seem lumpy at first but keep stirring and it’ll resemble cake batter in no time!
  2. Microwave on high until the cake has risen and springs back slightly when you poke it, 45-60 seconds. If it’s not done after 60 seconds, try cooking in 15-second intervals until done. (To bake in the oven, heat oven to 375 degrees Fahrenheit and place batter in an oven-safe ramekin or oven-safe mug. Bake until domed and the top springs back when you poke it, 15-20 minutes. )
  3. Top with chocolate chips or chunks if desired and enjoy right away.

Nutrition information is for one mug cake without chocolate chips.

Dairy option:

Use cow’s milk instead of almond milk.

Gluten-free option:

Substitute your favorite gluten-free flour blend – I have used Cup4Cup with success. Almond flour is also tasty but can throw the texture off a bit.
