Yes!Covert it into a banana cake and frost it with sweet, creamy peanut butter buttercream. While you’re at it, go ahead and sprinkle on some colorful nonpareils for extra credit. I made this peanut butter banana layer cake for my husband’s recent birthday. Over the years, I’ve made him quite a few: baseball cap cake, giant donut cake, coconut raspberry cake. Traditionally, we get each other donuts for our birthdays. Being an overachiever, I also bake him a cake every year. (And I’m happy to do so.) Banana Cake with Peanut Butter Frosting The base of this banana layer cake is very similar to the ones I used in these recipes: banana cake with whipped sea salt caramel, walnut banana rum cake, and peanut butter banana bacon cake. As with banana bread, this layer cake is best made with ripe bananas. Banana cake is only as sweet and flavorful as the ripe bananas you use. Bananas are ready when its peel is heavily speckled with brown spots. It should be soft to the touch. Easy Peanut Butter Buttercream The peanut butter buttercream used for this cake is a quick variation on the standard American buttercream. Smooth peanut butter is whipped with softened butter and powdered sugar. The buttercream works best using a no-stir homogenous peanut butter like Jif or Skippy.ย If you use a natural peanut butter that requires stirring, the buttercream may separate in the fridge. This cake rather plain and simple from the outside. It’s the kind of no-frills cake you easily bake during the week! Cake Storage Assembled cake can be left at room temperature for up to 24 hours. Once cake has been sliced, use a small piece of wax paper or parchment paper to cover exposed cake areas. This will prevent cake layers from drying out. Hold cake in the fridge for longer storage. Let sit at room temperature for 30 minutes or so to allow cake to soften.

Maryanne Cabrera says: July 1, 2021 Hi! I have not baked this specific recipe in 8-inch cake pans. I suggest baking for 25-28 minutes. Check for doneness using a toothpick inserted in center of cake.
