1. Gather all necessary ingredients, including your chosen protein powder, binding agent, and flavorings.
2. In a medium bowl, combine your preferred nut butter, unsweetened applesauce, and vanilla extract. Whisk until smooth.
3. Gradually add the protein powder to the wet mixture. Stir well to avoid lumps.
4. Continue mixing thoroughly until a thick, uniform consistency forms. If the mixture is too dry, add a tiny bit of water or milk (1/2 teaspoon at a time). If it's too wet, add a touch more protein powder.
5. Taste the dough and add zero-calorie sweetener to your preference, mixing well.
6. Fold in mini chocolate chips or other desired mix-ins, distributing them evenly throughout the dough.
7. Serve immediately or refrigerate for later enjoyment. Store in an airtight container in the refrigerator for up to 3-5 days.
