That looks incredible! Mug cakes are absolute lifesavers when a random dessert craving hits at night and you don’t want to deal with preheating the oven or washing a stack of bowls.
A warm, fluffy peanut butter mug cake soft right in the middle is peak comfort food.
If you want to recreate it easily or mix things up next time, here is a quick, classic formula that delivers that exact soft texture:
The 2-Minute Peanut Butter Mug Cake
Ingredients
- 1 tbsp peanut butter (creamy works best)
- 1 tbsp melted butter or vegetable oil
- 2 tbsp milk
- 1 tbsp sugar (brown or white)
- 3 tbsp all-purpose flour
- ¼ tsp baking powder
- Optional: Pinch of salt, a dash of vanilla, or a handful of chocolate chips stirred into the center.
Quick Steps
- Mix Wet Ingredients: In a microwave-safe mug, whisk together the peanut butter, melted butter/oil, milk, and sugar until smooth.
- Add Dry Ingredients: Stir in the flour and baking powder just until combined (don’t overmix!).
- Microwave: Cook on high for 45 to 60 seconds. It should rise and look set on top, but stay soft in the center.
- Finish: Warm a small spoonful of peanut butter for 5–10 seconds and drizzle it over the top like in your photo!
Tip: Every microwave is a little different, so start checking at 45 seconds—taking it out right when the top looks just barely set keeps that center super soft and gooey instead of rubbery!
