Why I Love This Brown Butter Banana Cake
So I kind of become obsessed with things. Well, more so, I go in phases. There was a year when it seemed I had an avocado a day. Then I started buying grapes in bushels, freezing them, and eating them constantly. More recently, my obsession of choice has been bananas. Seriously, I can’t stop eating them! This is obviously why bananas are the inspiration for my Easter dessert. I took my current favorite fruit and added the flavors that complement it perfectly. Really, though, what doesn’t pair well with brown butter?! This cake is the perfect mix of banana bread, bars, and caramel-like browned butter.
I like the rustic look with the unfinished sides, but you choose. This is such an indulgence and perfect for a spring celebration!
