Prep Time 5 minutes
Cook Time 2 minutes
Total Time 6 minutes
Servings: 1
Course: Dessert, Snack
Cuisine: American

Ingredients
  

  • 2 packets butter (approximately 1 tbsp total), melted
  • ½ inch ripe banana
  • ¼ packet brownie mix
  • 1–3 tsp water, as needed
  • candy bar of choice, chopped (optional)
  • ¼ packet brownie mix
  • 1 packet mayonnaise (single serve)
  • 1–3 tbsp water, as needed
  • candy bar of choice, chopped (optional)

Method
 

  1. Pour approximately one quarter of the brownie mix packet into a paper cup or mug
  2. Stir in the mayonnaise packet until the mixture is combined — it will be crumbly at first
  3. Add water a tiny bit at a time, stirring after each addition, until the batter is thick but stirrable
  4. Stir in chopped candy if using
  5. Microwave for 90 seconds, then check — a fork inserted in the center should come out clean. Continue in 30-second intervals if needed

Notes

Mayonnaise is simply oil and egg, so it works perfectly as a substitute for both in brownie mix. You cannot taste it in the finished brownie — chocolate is too overpowering. Single-serve mayo packets can often be found near condiment stations at Dunkin Donuts or similar spots, not just in pre-wrapped sandwiches
