Notes

Sheet Pan Banana Bars
To make a 13x18" half sheet pan of banana bars, double all batter ingredients except for eggs (use 3 eggs). Spread in a greased half sheet pan and bake for 28-30 minutes.
You don't need to double the frosting recipe, as that would be too much. You can either use the same amount and spread it a little thinner or make 1.5 batches of frosting.
Cover banana bars with plastic to keep them fresh for up to 5 days.
