This Chocolate Peanut Butter Mug Cake tastes just like a slice of chocolate cake, but it takes so much less work to make. Just whisk the ingredients together, pop it in the microwave, and enjoy that rich chocolate goodness!
In a large mug, whisk (with a small whisk or large fork) together the dry ingredients (flour, sugar, cocoa powder, baking powder and salt). Add the milk, vegetable oil and peanut butter. Whisk until smooth.
Cook in the microwave on high for 1 minute and 10 seconds. This recipe will rise a lot and then deflate. I know it’s strange, but trust me it’s delicious! Serve immediately!
Use a Big Mug: Make sure you use a roomy mug so that the batter doesn’t overflow.Stir Well: You don’t want to end up with dry bits of flour or baking powder in your cake, so be sure to stir the batter really well. A mini whisk makes this super easy, but a fork will also work.Mix-Ins: Sometimes I like to stir in mini marshmallows or some chopped walnuts to add a little something different. Add both, and it’s like a Rocky Road Mug Cake.Toppings: Feel free to add a scoop of ice cream, powdered sugar, or even some chocolate frosting to this cake when it’s done. Or add a dollop of whipped cream and a peanut butter drizzle, like you see here in the photos!Milk Substitute: You can use unsweetened brewed coffee, to help deepen the flavor of the chocolate and make it almost like a mocha cake. Or any non-dairy milk substitute will work! Even water will work!
