This Overnight Peanut Butter French Toast Casserole is an easy, make ahead breakfast that's perfect for Thanksgiving or Christmas brunch! It's a new twist on a favorite that everyone will love!
Slice bread into ½-1" cubes and place in a lightly greased 8x8" baking dish.
In a large bowl, whisk together eggs, milk, peanut butter, maple syrup and vanilla until as smooth as possible (if there are a few peanut butter lumps left, that's okay! You will just have little pockets of peanut butter in your casserole). Pour over bread cubes in dish.
Cover with plastic wrap and refrigerate at least 2 hours or overnight.
Bake at 350 degrees F for 30-40 minutes, until golden brown on top and completely set.
Serve with fresh fruit (banana are my favorite!), and extra syrup, or as desired.
