Peanut butter and banana are probably one of life's greatest combinations!
Did you know I used to be heavily reliant on peanut butter to the extent that I would have LARGE spoonfuls of my best-friend/housemates peanut butter supply every night. Here's me thinking she wouldn't notice... perhaps the large crater in the peanut butter gave it away, I'm not sure. Perhaps the empty jar gave it away.. also not sure.
Here is the recipe for you!
