Step 1: Preheat your oven to 350°F (175°C). This ensures your cookie will bake evenly and come out perfectly golden brown.
Step 2: In a food processor, add the rinsed and drained chickpeas. Blend until smooth, scraping down the sides as needed.
Step 3: To the blended chickpeas, add the old-fashioned rolled oats, natural peanut butter, pure maple syrup, vanilla extract, ground cinnamon, baking powder, kosher salt, and milk. Blend again until all ingredients are well incorporated and you have a smooth batter.
Step 4: Transfer the batter to a mixing bowl and fold in the semisweet chocolate chips. This will add pockets of gooey chocolate throughout your cookie.
Step 5: Pour your batter into the skillet, spreading it evenly. Sprinkle the additional chocolate chips on top for that extra touch of deliciousness. Bake in the preheated oven for 25-30 minutes, or until the edges are golden and the center is set.
Step 6: Once baked, remove the skillet from the oven and let it cool for a few minutes. Slice your Healthy Peanut Butter Skillet Cookie into wedges and serve warm, perhaps with a scoop of ice cream for an extra treat!
