How to Make It

Make this delicious mug cake in just a few simple steps.

1. Whisk dry ingredients

In a microwave-safe mug (12 oz or larger), add the all-purpose flour, granulated sugar, cocoa powder, baking powder, and salt. Whisk everything together until combined.

2. Mix wet ingredients

Pour in the milk, peanut butter, vegetable oil, and vanilla extract. Mix well until a smooth batter forms, making sure to scrape the sides and bottom of the mug.

3. Fold in chocolate chips

If desired, fold in some chocolate chips for an extra chocolaty touch.

4. Microwave

Microwave the mug on high for 1 minute and 30 seconds, checking to see if it’s cooked through. If it still looks wet in the center, continue to microwave in 15-20 second intervals until done (it might take up to 2 minutes total depending on your microwave).

5. Cool and top

Remove the mug from the microwave (it will be hot!) and let it cool for a minute. Top with chopped peanuts and additional chocolate chips if desired.

How to Store It

Fridge: Store in an airtight container for up to 2 days.
Freezer: No, best served fresh.
Reheat: Microwave for 15-20 seconds.
