Sometimes all you need in life is a little cake. Am I right?

If I could bake layered cakes all the time, I would. It tends to be pretty time consuming so I like to save it for special occasions, such as birthdays or holidays. Even though this cake took me a few hours to bake up and frost, it was completely worth it.

I baked this with Easter in mind. Sometimes it’s fun to go outside the tradition of carrot cake and bake something to surprise everyone. Just imagine pulling this out and setting it on the table. Minds will be blown. Like did you just make a triple layered cake? Wait it tastes like a fluffy banana bread. Oh and there’s chocolate in there? Wait and a frosting that tastes like the inside of a peanut butter cup?

Oh.em.gee. I know.

I can’t tell you how much I LOVE this cake! The frosting is magically fluffy, silky-smooth, and probably a little too addicting. I had everyone at the video shoot stealing frosting from the bowl. Why must I love peanut butter so much?

And hey, if you want to get real crazy, you could use chopped Reese’s Peanut Butter Cups instead of chocolate chips in this recipe. I think you’d probably get your boyfriend to propose to you by doing this, so good luck.

Are you guys liking these videos? Would love to hear what you’d like to see next!

Happy baking! xoxo
