How to Make Baked Cinnamon Banana Protein Squares

Preheat oven: Preheat your oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper or grease lightly for perfect golden-brown edges.
Mash bananas: In a medium bowl, mash 3 ripe bananas until smooth with a few small lumps for texture. The mixture should be silky and pale yellow.
Mix dry ingredients: In another bowl, whisk 1½ cups rolled oats, 1 scoop protein powder, 2 tsp ground cinnamon, 1 tsp baking powder, and a pinch of salt until uniform.
Combine mixtures: Pour wet banana mix into the dry ingredients bowl. Add 2 eggs, 2 tbsp honey, and 1 tsp vanilla extract. Stir gently until a thick, golden batter forms.
Bake squares: Spread batter evenly in the prepared pan. Bake at 350°F for 20–25 minutes, until the top is set and lightly golden. A toothpick should come out clean.
Cool before slicing: Let the baked squares rest in the pan for 10 minutes. This helps them firm up for clean slices and maintains that soft, tender texture inside.
Serve and enjoy: Transfer to a cutting board, slice into 9 squares, and serve warm. Enjoy these cozy protein-packed treats with a cup of coffee or tea.

Optional: Sprinkle with a dash of cinnamon sugar before serving.
