How to Make Decadent Chocolate Peanut Butter Mug Cake
This mug cake comes together in a flash, with just a few simple steps. Let’s get cooking!
Step 1: Prep Work
Start by gathering all your ingredients in one place. Grab a microwave-safe mug (or ramekin) and give it a quick spray with nonstick cooking spray. This will help your cake release easily when it’s done.
Step 2: Main Cooking Process
In your prepared mug, whisk together the flour, sugar, cocoa powder, and a pinch of salt until well combined. Then, stir in the milk, peanut butter, egg, and vanilla. Mix everything together until you have a smooth, lump-free batter.
Step 3: Final Steps/Assembly
Microwave the mug cake for 60-90 seconds, or until the center is just set. Be careful not to overcook it, or it can become dry and tough. When it’s done, let it cool for a minute or two before digging in.
Step 4: Finishing Touches
For an extra decadent touch, top your warm mug cake with a dollop of whipped cream, a sprinkle of chopped peanuts, or a drizzle of melted peanut butter or chocolate sauce.
Variations & Time-Saver Tips
- Dark Cocoa Powder: Use dark cocoa powder instead of regular for an even richer, more intense chocolate flavor.
- Greek Yogurt: Swap some of the milk for Greek yogurt for a moister, creamier cake.
- Chocolate Chips: Fold in a spoonful of chocolate chips for extra gooey pockets of chocolate.
- Cinnamon or Sea Salt: Add a dash of cinnamon or a sprinkle of sea salt to the batter for a flavor twist.
Serving, Storage & Reheat
Serve with: a dollop of whipped cream, chopped peanuts, or a drizzle of peanut butter or chocolate sauce.
Storage: Store any leftovers, covered, in the refrigerator for up to 3 days.
Microwave Reheat: Reheat the mug cake in the microwave for 20-30 seconds before serving.
Make-Ahead: You can mix up the batter in advance and keep it in the fridge until you’re ready to bake. Just give it a quick stir before microwaving.
