Peanut Butter Mug Cake (Vegan)

Peanut Butter Mug Cake – rich peanut butter cake studded with chocolate chips, ready in under a minute!

Peanut Butter Mug Cake

A few days ago, I ran into a problem that I haven’t had in years: there was no dessert in the house.

I was craving something warm and gooey and chocolatey, but my emergency freezer cookie stash had run out. And to be honest, the past two weeks have worn me out with recipe testing and editing videos and trying to get ahead on everything, so the last thing I wanted to do was bake cookies.

I found a small bit of vanilla ice cream (Soy Creamy from Trader Joe’s, absolutely the best vegan ice cream in the world) in the back of the freezer and knew that I was halfway to a pizookie, or at least something vaguely pizookie-like, aka anything warm with cold ice cream on top.

Mug cakes are not a thing I make too often, but every once in a while they show up to save the day. This was one of those times.

A warm peanut butter mug cake with melty chocolate chips, topped with vanilla ice cream? So ridiculously good. In fact, I bought more ice cream so that I could make another one.

This mug cake has such a great consistency, I almost didn’t believe it was baked in a mug. It’s soft enough to eat on its own, but sturdy enough to hold up to ice cream and chocolate sauce. And it all comes together in under 2 minutes? It’s a literal lifesaver.
