Notes

*You can really use any type of peanut butter or nut butter here. Creamy, crunchy, almond, or even Nutella would be delicious!
**I like milk chocolate chips, but semisweet or dark will also work for a pop of chocolate. For an all-peanut-butter cake, swap the chocolate chips for peanut butter baking chips.
Tips:
  • Grease your mug before adding the ingredients so that it doesn't stick.
  • Make sure you use a microwaveable mug in this recipe.
  • Don't fill the mug all the way to the top, as the batter will rise as it cooks. Place a plate under your mug in case there is any spillage.
  • Microwave wattages can vary a lot! If your cake is underdone in 2 minutes, try 15-second bursts until just cooked through. Avoid overcooking to keep it soft and moist.
  • Use your fingertips to test the top of the cake; if it's a little sticky, it's perfectly cooked through and ready to eat.
  • Make this mug cake gluten-free by using 1:1 gluten free flour alternative.
  • Let cool slightly before enjoying.
Baking Instructions: If you don't have a microwave, you can bake these mug cakes in the oven. At 350°F, they will take around 25 to 30 minutes.
Storage: Store peanut butter chocolate chip mug cake tightly wrapped with plastic wrap in the refrigerator for up to 3 days.
