This single serving microwave flourless peanut butter cake comes out light and fluffy. You won’t miss the flour at all!
I had the biggest craving for a peanut butter flavored dessert today, so I whipped this up. The recipe is just 4 simple ingredients that you likely have in your kitchen and the cake stays moist for hours so you can enjoy it right away or later on too.
Do you have a recurring nightmare that you’re still in school and suddenly it’s finals and you’re completely unprepared? Even though I’ve been out of school for a decade, I still periodically have that nightmare. I wonder when, or if ever, it will go away.
I recently have been having a similar series of panic moments over my upcoming book. It’s been a few months now since I turned in the final draft, and every once in a while, I’ll find myself freaking out because I think I messed up one of the recipes even though I tested and retested all the recipes over and over again before turning in the book. That’s what happened when I made this mug cake. I looked up the recipe and noticed that the original recipe I posted two years ago and the one in the book are different.
So I started panicking, but luckily, it was all for nothing. The recipe does work as written (just like all the other ones I recently freaked out over). It is one of the ones I tinkered and improved upon for the upcoming book.
I really enjoy how easy this recipe is. It expands quite a bit in the microwave before deflating a little after it has cooled. It has a sweet, pleasant peanut butter flavor. It also continues to stay moist for hours and the peanut butter flavor actually becomes more prominent if you let it sit for a few hours, though it tastes great straight from the microwave too.

As mentioned above, this recipe is featured in my new cookbook of nearly 100 mug cakes!
