Forget those rubbery, sad microwave cakes you’ve tried before. This version uses a few “upgraded” pantry staples to give you a rich, tender crumb that feels like it actually came out of a bakery—not a mug. It’s the perfect salty-sweet fix for late-night cravings.

Ingredients

  • Creamy Peanut Butter: 2 tbsp (Standard brands like Jif work best)
  • Oil: 1.5 tbsp (Vegetable or canola)
  • Sugar: 2 tbsp (Granulated white sugar)
  • Egg Yolk: 1 large (The secret to a moist, non-spongy texture)
  • All-Purpose Flour: 2 tbsp
  • Baking Powder: 1/4 tsp
  • Milk: 1 tbsp (Plus an extra splash if the batter is too dry)
  • Chocolate Chips: 1 tbsp (Optional, but highly recommended)

Instructions

  1. Cream the Base: In a 10–12 oz microwave-safe mug, whisk together the peanut butter, oil, sugar, and egg yolk. Keep going until the mixture looks like a smooth, shiny caramel paste.
  2. Add Dry Ingredients: Whisk in the flour and baking powder. Add them slowly to avoid any dry flour pockets hiding at the bottom.
  3. Finish the Batter: Stir in the milk and chocolate chips. The batter should be thick and creamy, similar to Greek yogurt.
  4. Microwave: Heat on high for 60 to 90 seconds. Stop when the top looks set and barely matte, not wet.
  5. The Critical Rest: Let the mug sit for 2 minutes. This allows the residual heat to finish the center without overcooking the edges.

Notes

Serving Suggestions

  • The Classic: Top with a scoop of cold vanilla ice cream for a “hot-cold” treat.
  • The Nutty: Drizzle a little extra warm peanut butter over the top.
  • The Fancy: Sprinkle a tiny pinch of flaky sea salt to balance the sugar.

Tips & Tricks

  • No Whisk? Use a dinner fork! It’s actually better at mashing the peanut butter into the liquids.
  • Natural PB: If your peanut butter is very stiff, zap the mug for 10 seconds before mixing to soften it up.
  • Room Temp: Using a room-temperature egg yolk and milk helps the batter stay smooth and prevents clumping.

Storage & Reheating

  • Enjoy Now: This is definitely best eaten right away.
  • Leftovers: If you have to wait, cover with plastic wrap for up to 3 hours.
  • Reheat: Zap for 10–15 seconds to bring back that melty, gooey center.
