How to Make Peanut Butter Cake Mug
Gather Your Ingredients : Start by assembling all your ingredients in one place—it makes for smoother cooking and less mess later on. Trust me, it’s worth it.
Mix Dry Ingredients : In a microwavable mug, combine flour, sugar, baking powder, and salt. Stir well until there are no lumps—this helps achieve that perfect cake texture.
Add Wet Ingredients : Pour in the peanut butter, milk, egg, and vanilla extract. Mix until fully combined; make sure to scrape down the sides of the mug so every bit is incorporated.
Mug It Up! : Place your mug in the microwave and cook on high for 1 minute and 30 seconds—or until the cake rises nicely without overflowing. Keep an eye on it since microwaves can be sneaky!
Check Doneness : Insert a toothpick into the center of the cake; if it comes out clean or with a few crumbs sticking to it, you’re golden! Let it cool slightly before diving in.
Dress It Up (Optional) : Get creative! Top with whipped cream, chocolate drizzle, or even more peanut butter if you’re feeling indulgent. Enjoy that heavenly goodness!
