Description

Midnight cravings meet their match with this Peanut Butter Brownie in a Mug, a quick chocolate-peanut indulgence ready in minutes. Creamy peanut butter swirls through rich chocolate, creating a single-serve dessert that satisfies without complicated kitchen work.


Ingredients

Scale

Dry Ingredients:

  • 4 tbsp all-purpose flour
  • 3 tbsp cocoa powder
  • 3 tbsp granulated sugar
  • 1/4 tsp baking powder

Wet Ingredients:

  • 3 tbsp milk
  • 2 tbsp vegetable oil
  • 1 large egg
  • 1 tsp vanilla extract

Peanut Butter Components:

  • 2 tbsp peanut butter
  • 1 tbsp peanut butter chips
  • 1 tsp chocolate chips (optional)

Instructions

  1. Gather all dry ingredients in a microwave-safe mug, whisking flour, cocoa powder, sugar, and baking powder until uniformly combined.
  2. Create a small well in the center of the dry mixture, then pour in milk, vegetable oil, egg, and vanilla extract.
  3. Vigorously mix all ingredients with a fork until the batter becomes smooth and free of lumps, ensuring complete incorporation.
  4. Drizzle peanut butter across the surface of the batter, using a knife or spoon to create delicate swirls throughout the mixture.
  5. Sprinkle peanut butter chips and optional chocolate chips on top of the batter, distributing them evenly.
  6. Microwave the mug on high power for 60-90 seconds, watching carefully to prevent overcooking. The brownie is done when it rises slightly and appears set in the center.
  7. Allow the mug brownie to rest for 1-2 minutes after microwaving, as it will continue to set and develop a richer texture.
  8. Serve warm, optionally garnishing with an extra dollop of peanut butter or a sprinkle of chocolate chips for added indulgence.

Notes

  • Swirl peanut butter delicately to create beautiful marbled patterns, ensuring even distribution without overmixing the batter.
  • Check microwave power carefully since wattages vary, start with 60 seconds and add incremental time to prevent dry or rubbery texture.
  • Substitute dairy milk with almond, oat, or coconut milk for lactose-free versions, maintaining the same liquid measurement ratio.
  • Replace egg with mashed banana or applesauce for vegan alternative, which adds moisture and helps bind ingredients similarly.
