Chocolate Peanut Butter Oatmeal Bars: How It’s Done

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This step ensures that your bars bake evenly and achieve that perfect texture.
Step 2: Prepare Your Baking Dish
Grease a 9×9 inch baking dish with a little coconut oil or line it with parchment paper for easy removal later.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, combine the mashed banana, peanut butter, and coconut milk. Stir until the mixture is smooth and well combined.
Step 4: Add the Dry Ingredients
To the wet mixture, add the rolled oats, almond flour, cocoa powder, ground flaxseed (if using), and protein powder. Mix everything together until fully incorporated.
Step 5: Fold in the Peanuts
Gently fold in the chopped peanuts, adding a delightful crunch to your bars.
Step 6: Spread the Mixture in the Baking Dish
Pour the mixture into your prepared baking dish. Use a spatula to spread it evenly, making sure to reach the corners.
Step 7: Bake
Place the baking dish in the preheated oven and bake for 25-30 minutes. The edges should be firm, and the center should be set.
Step 8: Cool and Cut
Remove the bars from the oven and let them cool in the baking dish for about 10 minutes. Then transfer them to a wire rack to cool completely before cutting into squares.

Your Questions, Answered
Can I replace the peanut butter with another nut butter?
Absolutely! Almond butter, cashew butter, or sunflower seed butter can be great alternatives if you prefer a different flavor or have a nut allergy.
