Step‑by‑Step Instructions for Protein Cookies
Step 1: Preheat Your Oven
Start by preheating your oven to 180°C (350°F) to ensure it’s ready for baking. While the oven warms up, line a baking sheet with parchment paper—this will prevent the cookies from sticking and make cleanup a breeze. Having these steps prepped helps set the stage for your delicious Protein Cookies!
Step 2: Mix the Ingredients
In a mixing bowl, combine 1 cup of peanut butter, 1/2 cup of brown sugar substitute, 1 egg, and 1 scoop of vanilla protein powder. Using a spatula or wooden spoon, stir the mixture until it is fully incorporated and smooth, which should take about 2-3 minutes. The dough will be thick but cohesive, ready for shaping into cookies!
Step 3: Shape the Cookies
Once your dough is mixed, use your hands to form it into 12 equal balls, about the size of a golf ball. Place each ball on the prepared baking sheet, spacing them a few inches apart. Gently press each ball down with your palm to flatten them into cookie shapes, which ensures even baking and gives you that perfect chewy texture.
Step 4: Bake
Carefully place the baking sheet in your preheated oven and bake the Protein Cookies for 12-14 minutes. Keep an eye on them, looking for golden brown edges as a sign they’re done. Avoid overbaking; this helps maintain a chewy center that you’ll love!
Step 5: Cool Before Enjoying
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 10 minutes. This cooling time allows them to set and finish cooking through without becoming too crispy. After that, you can transfer them to a wire rack to cool completely before indulging in your tasty Protein Cookies.
