Description
A quick and comforting single-serving mug cake featuring rich peanut butter flavor and a tender crumb.
Ingredients
Scale
- 4 tablespoons self-rising flour
- 3 tablespoons granulated sugar
- 4 tablespoons creamy peanut butter (about 64 g)
- 3 tablespoons whole milk (about 45 g)
- 3 tablespoons salted sweet cream butter, melted (about 42 g)
- 1/2 teaspoon pure vanilla extract
- Optional for garnish: 1 tablespoon creamy peanut butter (for topping)
- Optional gooey center: 1/2 tablespoon creamy peanut butter
Instructions
- Choose a microwave-safe mug (10–12 oz capacity is ideal so batter doesn’t overflow).
- In the mug, whisk together self-rising flour and granulated sugar until evenly combined.
- Add creamy peanut butter, whole milk, melted salted butter, and vanilla extract. Stir vigorously until the batter is smooth and uniform.
- Optional: For a molten center, drop 1/2 tablespoon of peanut butter into the center of the batter and gently push it down so it is submerged.
- Microwave on high for 60 to 70 seconds. Check doneness by inserting a toothpick; it should come out mostly clean with a few moist crumbs.
- Let the cake rest for 1–2 minutes to finish setting and avoid burns.
- Top with the remaining 1 tablespoon peanut butter (if using), a dusting of powdered sugar, or a drizzle of chocolate; serve warm straight from the mug.
Notes
For healthier swaps, consider lower-fat milk or skipping the butter. Be sure to use room-temperature peanut butter for smooth blending.
