Preheat your oven to 350°F (180°C).

In a medium bowl, mix together ⅓ cup of peanut butter powder with 4 tablespoons of water until smooth.

Add ¼ cup of natural peanut butter and ⅓ cup of maple syrup, blending until creamy.

Add the remaining ⅓ cup of peanut butter powder, ½ cup of oat flour, and 1 teaspoon of baking powder. Mix until a cohesive dough forms.

Roll small portions of the dough (about 1.5 tablespoons each) into balls, flatten them, and create a crisscross pattern with a fork.

Place cookies on a baking sheet and bake for 6-8 minutes until edges look set.

Let cool on the baking sheet for 5-10 minutes, then transfer to a wire rack to cool completely.
