- 1 1/2 cups unsalted butter
- 1/2 cup brown sugar
- 1/4 cup honey
- 3.5 cups rolled oats
- 1/2 cup hazelnuts or hazelnut meal
- 1/2 cup protein powder (optional)
- 1 teaspoon cinnamon
- 1 teaspoon baking powder
- 2 small bananas, mashed
Preheat oven to 350°F and grease an 8in X 12in sheet pan with butter.
Melt butter, sugar and honey in a large saucepan over low heat. Remove from heat and stir in oats, protein powder (if using), hazelnuts (or meal), cinnamon, baking powder and bananas. Stir until well combined.
Spoon into prepared tray and smooth the surface with finger tips dipped in cold water (the water prevents the mixture sticking to your hands).
Bake for 15-20 minutes until golden brown. Cool in the pan, then transfer to a large chopping board to cut into rectangles.
