This peanut butter banana bacon cake consists of four banana cake layers with banana filling and peanut butter frosting.
Today is one of my best friend’s birthday. She happens to share her birthday with Elvis. Elvis made famous the peanut butter, banana, and bacon sandwich. Its a delicious combination. The creamy peanut butter, caramelized sweet bananas, with the smokey and savory bacon creates a sweet and salty paradise. The flavor profiles work so well with each other that I decided to translate that sandwich into a special birthday cake.
So back to my best friend. I’ve know her since I was seven years old. Its hard to imagine we’ve known each other for 20 years. Don’t do the math. Let’s just say we’re turning 21 this year and every year until I say otherwise.
As children we would bake cookies at my house all the time. Unfortunately, we were terrible in the kitchen.
This one time, we measured out a cup of salt instead of a cup of sugar for a snickerdoodle recipe.
And then this other time, our oven mitts caught on fire while we removing a sheet tray from the oven.
Over the years, we have had our share of adventures, travels, and experiences together. I cherish the fact that my memories with her are full of smiles and laughter. She has always been my partner in crime. Our friendship will stand the test of time, very much like peanut butter/banana/bacon. Plus, we know way too much blackmail information about each other to ever stop being friends.
Happy birthday, Gina! (aka Beau, Dancing Queen, Laughing Hyena) xoxo, Peppy
