To prepare a banana fudge walnut brownies baked goods recipe, first you need to prepare the ingredients. First, you'll need: 1 cup (240 g) rolled oats, 1 tablespoon (25 ml) brown sugar, and 1 teaspoon vanilla extract. Then, add the wet ingredients to the dry ingredients and stir to combine. Pour the batter into the greased and floured muffin tins and bake for 20 to 25 minutes, or until the toothpick inserted in the center comes out clean. Allow to cool before cutting into squares.
