1. Prepare Oven & Dish: Get your oven ready by preheating it to 350°F (175°C). Then, line an 8x8 inch (20x20 cm) baking dish with parchment paper, allowing some to hang over the sides for easy removal later.
2. Mix Wet Ingredients: In a large mixing bowl, combine the melted peanut butter, mango puree, pure maple syrup, brown sugar (or coconut sugar), and almond milk. Whisk everything together until you have a smooth, well-blended mixture.
3. Combine Dry Ingredients: Grab a separate medium bowl and whisk together the baking powder, ground cinnamon, ground cardamom (if you're using it), sea salt, the 2 cups of gluten-free rolled oats, and the ½ cup of blended oat flour. Make sure they're all mixed evenly.
4. Fold Everything Together: Gently add the dry oat mixture into your wet ingredients, stirring until everything is just combined. Now, fold in the â…“ cup of dark chocolate chips.
5. Bake to Golden Perfection: Pour the batter into your prepared baking dish, spreading it out evenly. For an extra touch, sprinkle a few more chocolate chips on top. Bake for 32 to 36 minutes, or until the edges look golden brown and a toothpick inserted into the center comes out mostly clean.
6. Cool & Enjoy: Let the bars cool completely in the dish on a wire rack. Once cool, use the parchment paper overhang to lift the entire slab out. Slice into 16 delicious squares. These healthy, summery bars are perfect as a snack or a light breakfast!
