Breakfast brownies are a fun and indulgent way to start the day with a sweet, yet somewhat healthy treat. Start by preheating your oven to 350°F (175°C) and greasing a baking pan. In a bowl, combine 1 cup of rolled oats, 1/4 cup of whole wheat flour, 1/4 cup of unsweetened cocoa powder, 1/2 teaspoon of baking powder, and a pinch of salt. In another bowl, mix 1/2 cup of mashed bananas (about 1 banana), 2 eggs, 1/4 cup of honey or maple syrup, 1/2 teaspoon of vanilla extract, and 1/4 cup of milk. Stir the wet ingredients into the dry ingredients until combined, and then fold in 1/4 cup of dark chocolate chips or chopped dark chocolate. Pour the batter into the prepared pan and bake for about 20-25 minutes, or until a toothpick inserted comes out clean. Let the brownies cool slightly before slicing. Enjoy these delicious, fudgy breakfast brownies with a cup of coffee or as an on-the-go snack!
