What You’ll Need for Your Chocolate Peanut Butter Mug Cake
- ¼ cup flour (all-purpose works best, but gluten-free flour can be substituted)
- 2 Tablespoons cocoa powder (unsweetened for rich chocolate flavor)
- 2 Tablespoons sugar (granulated or substitute with coconut sugar for a healthier option)
- ¼ teaspoon baking powder (ensure it’s fresh for the best rise)
- ¼ cup milk (any type of milk works—dairy, almond, oat, etc.)
- 2 Tablespoons butter, melted (or use coconut oil for a dairy-free alternative)
- 1 Tablespoon creamy peanut butter (crunchy can be used for added texture)
- ¼ teaspoon vanilla extract (pure vanilla adds the best flavor)
- 1 Tablespoon mini chocolate chips (or chopped chocolate for a gooey center)
How to Make Your Mug Cake in Minutes
- Mix dry ingredients: In a small bowl, whisk together the flour, cocoa powder, sugar, and baking powder until fully combined.
- Add wet ingredients: Whisk in the milk, melted butter, and vanilla extract until the batter is smooth and lump-free.
- Fold in chocolate chips: Gently stir in the mini chocolate chips to evenly distribute them throughout the batter.
- Prepare the mug: Pour the batter into a large microwave-safe mug, ensuring it’s no more than halfway full to prevent overflow.
- Add peanut butter: Dollop the peanut butter into the center of the batter, gently pressing it down until it’s level with the top of the batter.
- Microwave: Cook on high for 1 minute. Check for doneness—the cake should be firm but slightly springy to the touch. If needed, microwave in 10-second intervals until done.
- Cool and serve: Let the mug cake cool for 1 minute before enjoying. Top with extra peanut butter or chocolate chips if desired!
Topping Ideas to Elevate Your Mug Cake
Take your Chocolate Peanut Butter Mug Cake to the next level with these delicious toppings! Add a dollop of whipped cream or a scoop of vanilla ice cream for a creamy contrast. Drizzle extra peanut butter or chocolate syrup on top for a decadent finish. For a crunchy twist, sprinkle crushed peanuts or mini chocolate chips over the cake before serving.
Perfect Pairings: Serving Suggestions
This mug cake is a delightful treat on its own, but pairing it with a cold glass of milk or a cup of coffee makes it even better. If you’re feeling fancy, serve it alongside fresh berries like strawberries or raspberries for a refreshing balance. It’s also a great dessert to enjoy after a cozy dinner or as a quick midday snack.
Quick Storage and Reheating Tips
If you have leftovers (though it’s hard to resist!), let the mug cake cool completely, then cover it with plastic wrap or a lid. Store it in the fridge for up to 2 days. To reheat, microwave it for 15-20 seconds until warm. For best results, add a fresh drizzle of peanut butter or chocolate syrup after reheating.
Fun Recipe Variations to Try
Switch things up by using almond butter or Nutella instead of peanut butter for a different flavor profile. You can also swap the mini chocolate chips for white chocolate chips or butterscotch chips. For a nut-free version, skip the peanut butter and add a tablespoon of caramel sauce or marshmallow fluff instead.
Time-Saving Tips for Busy Bakers
To make this recipe even quicker, pre-measure your dry ingredients and store them in a small jar or bag. When you’re ready to bake, just add the wet ingredients and microwave! This is also a great recipe to double if you’re sharing—just use two mugs and microwave them one at a time.
