To prepare a spiced banana cookie wreaths cookies recipe, first you need to gather your ingredients. First, you'll need: 1 1/2 cups rolled oats, 1 cup brown sugar, 1/2 cup butter, and 1 teaspoon vanilla extract. You can find these ingredients at your local grocery store, or you can buy them online. Then, add your dry ingredients to the wet ingredients and mix until they're just combined. Next, preheat your oven to 375 degrees F (190 degrees C) and grease your cookie sheet with non-stick cooking spray. Bake your cookies for 10 to 12 minutes or until the edges are golden brown. Allow the cookies to cool on the baking sheet for 5 to 10 minutes before removing them from the oven.
