Cinnamon Roll Banana Bread Cake

Preheat oven to 350F and prepare a brownie pan. In a bowl, mix the wet ingredients (mashed bananas, eggs, olive oil, maple syrup, brown sugar, and vanilla) together until well-combined. In a separate bowl, mix the dry ingredients (almond flour, oat flour, sea salt, baking powder, and cinnamon) until uniform. Add the dry mixture to the wet and fold until uniform. Transfer batter to the prepared pan and top with the cinnamon sugar mixture (1/3 cup granulated sugar + 2 tbsp cinnamon, combined). Swirl the cinnamon sugar mixture into the batter, then bake for 45-50 minutes or until a toothpick comes out clean. Let cool completely before icing! Prepare the icing glaze (1 cup powdered sugar + 2 tbsp milk, mixed until smooth) and let it cool before slicing.
