How to make Chocolate Oat Cookies

• Prepare the oven and baking tray – I preheat the oven to 350°F (180°C) and line a baking tray with parchment paper to prevent the cookies from sticking.

• Mix the dry ingredients – I whisk together the oat flour, rolled oats, cocoa powder, baking soda, and a pinch of salt in a large bowl until everything is evenly combined.

• Prepare the wet ingredients – In a separate bowl, I whisk together the natural peanut butter, Greek yogurt, maple syrup, egg, and vanilla extract until the mixture is smooth and creamy.

• Make the cookie dough – I add the dry ingredients to the wet ingredients and stir until a thick dough forms. If I’m using macadamia nuts, I gently press 2–4 nuts onto each cookie before baking.

• Shape the cookies – I scoop portions of the dough onto the prepared baking tray, leaving a little space between each cookie. I gently flatten each one with the back of a spoon.

• Bake the cookies – I bake the cookies for 11–13 minutes, until the edges are set but the centers are still slightly soft.

• Cool and enjoy – I let the cookies cool on the baking tray for 5 minutes, then transfer them to a wire rack to cool completely. I enjoy them as a wholesome snack, breakfast, or healthier dessert.
