I remember one particularly dreary Tuesday. Deadlines were looming, and my energy was at an all-time low. That's when the idea struck me: a mug cake.

This recipe isn't just about satisfying a sweet tooth; it's about giving yourself a little hug when you need it most. What does this mean for you?

🍽 Ingredients

📖 Instructions

  1. Grab your favorite mug: An average-sized mug (around 12-14 ounces) works best. Make sure it's microwave-safe, obviously.
  2. Melt the butter: In the mug, melt 2 tablespoons of butter in the microwave. This usually takes about 20-30 seconds. Keep a close eye on it; you don’t want it to explode!
  3. Mix in the sugar: Add 2 tablespoons of granulated sugar to the melted butter and stir until well combined. It should form a slightly grainy paste. If it isn't, that is okay, you'll still be able to enjoy this.
  4. Add the peanut butter and cocoa powder: Stir in 2 tablespoons of peanut butter (creamy or chunky, your choice!) and 2 tablespoons of unsweetened cocoa powder. Mix thoroughly until everything is well incorporated. This is where the magic starts to happen!
  5. Incorporate the egg yolk and vanilla: Add 1 egg yolk and 1/2 teaspoon of vanilla extract. Mix until smooth. Pro-tip: Make sure your egg is fresh for the best flavor.
  6. Add the flour: Add 4 tablespoons of all-purpose flour to the mug. Gently fold it in until just combined. Be careful not to overmix; a few lumps are okay. Nobody likes overmixed flour.
  7. Stir in the milk: Add 2 tablespoons of milk (any kind works – dairy or non-dairy). Stir until the batter is smooth and creamy. The consistency should be like a thick cake batter.
  8. Add fudge pieces (optional but HIGHLY recommended): If you're using fudge pieces (about 1-2 tablespoons), gently fold them into the batter. If you don’t have any, don’t sweat it – it’ll still be amazing!
  9. Microwave: Microwave on high for 60-90 seconds. Cooking times may vary depending on your microwave, so start with 60 seconds and check for doneness. The cake should be puffed up and slightly set on top. This part is REALLY important.
  10. Let cool slightly: Let the mug cake cool for a minute or two before digging in. This will prevent you from burning your tongue, trust me!
  11. Enjoy: Devour your warm, gooey Peanut Butter Fudge Mug Cake straight from the mug! Add a scoop of ice cream or a drizzle of chocolate sauce for an extra-special treat.

📝 Notes

  • Microwave times may vary; adjust accordingly.
  • For a richer flavor, use dark cocoa powder.
  • Add a pinch of salt to enhance the sweetness.
  • Top with whipped cream, ice cream, or chocolate sauce for an extra treat!
