Ingredients
Ingredients
- 1 cup smooth peanut butter
- ¼ cup + 2 tablespoons pure maple syrup
- 1 ¾ cups gluten free rolled oats
Instructions
- Prepare the Pan: Lay a 24-mini-cup silicone baking pan on a medium baking sheet. This step ensures stability and makes it easier to remove the finished cookie cups. Set the pan aside for later.
- Mix Peanut Butter and Maple Syrup: In a large, microwave-safe bowl, combine the smooth peanut butter and pure maple syrup. Whisk them together until the mixture is smooth and well blended.
- Heat the Mixture: Microwave the peanut butter and syrup mixture in 20-second increments, whisking between each increment. Heat until the mixture is warm, fragrant, and just beginning to dry out, which usually takes about 4-7 rounds.
- Add Oats: Stir in the gluten free rolled oats using a rubber spatula or wooden spoon. Fold gently but thoroughly until the oats are completely coated and evenly mixed into the peanut butter mixture.
- Shape the Cookie Cups: Using a small cookie scoop, portion the dough into the wells of the silicone baking pan. Press and flatten each portion with the back of a spoon so the tops are smooth and the dough is evenly distributed. Any extra dough can be used in another pan or to make thicker cookie cups.
- Chill to Set: Place the pan in the freezer and chill for 15-25 minutes, or until the cookie cups are firm and hold their shape.
- Serve and Store: Enjoy the cookie cups immediately once they are firm. Store leftovers in an airtight container in the refrigerator for up to a week or in the freezer for longer storage.
Notes
- For stovetop heating: Warm the peanut butter and maple syrup gently in a small saucepan over low heat, stirring constantly until the mixture is warm and combined, then proceed with folding in the oats.
- These cookie cups are naturally gluten free when using certified gluten free oats.
- You can substitute maple syrup with honey or agave nectar if preferred.
- To make thicker cookie cups, use extra dough in additional silicone pan molds or press more dough into each cup before chilling.
- Storage: Keep cookie cups in an airtight container in the refrigerator up to 1 week or freeze for up to 3 months.
