Set out your bananas, peanut butter, and tortillas before you start. Having everything within reach makes the process smooth and fast. I like to peel the bananas last so they stay fresh and don't turn brown.
Place a clean cutting board or countertop in front of you. Lay one tortilla flat in the center. A flat, steady surface helps you roll without tearing the tortilla.
Scoop about three tablespoons of peanut butter onto the tortilla. Use the back of a spoon or a butter knife to spread it evenly. I always go right to the edges so every bite has that creamy flavor.
Peel one banana and place it along the edge of the tortilla. Keep it snug against the edge so the roll stays tight. If your banana is very long, you can trim it slightly to fit the tortilla.
Start from the banana side and roll the tortilla slowly and firmly. Keep it tight so there are no gaps inside. The peanut butter helps the end stick, so the roll holds itself together.
Do the same with the second tortilla, the remaining peanut butter, and the second banana. Work at the same pace so both rolls look alike. This is also a good moment to add Nutella if you like.
Use a sharp knife to cut each roll into small, bite-size pieces. Smaller pieces are easier for little hands and much less messy. I make them about an inch wide, which looks pretty on a plate.
Arrange the pieces on a plate and enjoy them fresh. They taste best soon after cutting, while the banana is bright and the tortilla is soft. Serve them as a snack, a quick breakfast, or a lunchbox treat.
