Step 1

Heat oven to 350°F (180°C) and fold a 7 x 7 inch (15 x15 cm) brownie pan with parchment paper.

Step 2

Wash the strawberries and remove the top. With the help of a knife, dice them into small pieces.

Step 3

In a large bowl, mash the ripe bananas. Add Greek yogurt, vanilla extract, and a pinch of salt. For sweetener bars, add 2 to 4 tablespoons of maple syrup or honey to taste. Stir until smooth.

Step 4

Add rolled oats and oat flour to the wet mixture, then stir until combined. If the batter is too thick, add a splash of milk or more yogurt.

Step 5

Fold the diced strawberries into the dough until fully incorporated.

Step 6

Transfer the dough to the prepared baking pan and spread it out evenly. Top with sliced strawberries, if desired.

Step 7

Bake in hot oven for 17 to 20 minutes, or until they have set in the center. Let cool to temperature, then slice into bars.
