This Overnight Monkey French Toast Casserole recipe has all of the flavors of peanut butter, bananas, and rich custard. It's an easy make-ahead breakfast that is such comfort food!
In a large frying pan over medium heat, melt 1 stick of butter and peanut butter together. Add brown sugar and cook until melted. Add bananas and stir for 1-2 minutes, until bananas start to break down. Remove from heat and set aside.
Cover tightly and place in the fridge overnight. When you're ready to serve, bake casserole in a 350 degree oven for 35-40 minutes, until middle is set and top starts to brown.
Melt 1/2 cup peanut butter in the microwave in 30 second increments until it is mixable and pourable. Top casserole servings with drizzled peanut butter and bananas.
