Step 1: Preheat the Oven - Start by preheating your oven to 350°F (175°C). This step is crucial as it ensures that your brownies bake evenly.
Step 2: Mix Wet Ingredients - In a large mixing bowl, combine the creamy peanut butter, honey, avocado oil, eggs, vanilla extract, and almond milk. Use a whisk to mix until the ingredients are well combined and smooth.
Step 3: Combine Dry Ingredients - In a separate bowl, whisk together the gluten-free oat flour, cocoa powder, gluten-free quick oats, baking soda, and salt. Ensure there are no lumps for a uniform brownie texture.
Step 4: Combine Wet and Dry Ingredients - Gradually add the dry ingredient mixture to the wet ingredients, stirring gently with a spatula until just combined. Be careful not to overmix.
Step 5: Add Chocolate Chips and Coconut Flakes - Fold in the semi-sweet chocolate chips and coconut flakes (if using) until evenly distributed throughout the batter.
Step 6: Bake the Brownies - Pour the brownie batter into the prepared baking dish, spreading it evenly. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Step 7: Cool and Slice - Once baked, remove the brownies from the oven and let them cool in the pan for about 10 minutes. Then transfer them to a wire rack to cool completely before slicing into squares.
