1. 1. Combine Dry Ingredients: In a large mixing bowl, combine the rolled oats and protein powder. Use a whisk or a spoon to ensure they are well mixed, breaking up any clumps of protein powder. This initial step ensures an even distribution of protein throughout your treats.

2. 2. Add Wet Ingredients: Pour in the peanut butter, honey (or maple syrup), milk, and vanilla extract into the bowl with the dry ingredients.

3. 3. Mix Thoroughly: Using a sturdy spoon or a rubber spatula, mix all the ingredients together. This will require a bit of effort as the mixture will be thick and sticky. Continue mixing until everything is fully incorporated and forms a cohesive dough. You shouldn’t see any dry pockets of oats or protein powder.

4. 4. Fold in Chocolate Chips (Optional): If using, gently fold in the mini chocolate chips until they are evenly distributed throughout the mixture.

5. 5. Form the Treats: Take small portions of the mixture, about 1 to 1.5 tablespoons each, and roll them between your palms to form bite-sized balls. You can also press the mixture into a small, parchment-lined square pan and cut them into bars later.

6. 6. Chill to Set: Place the formed treats on a plate or a baking sheet lined with parchment paper. Refrigerate for at least 20 minutes. This chilling time is crucial as it allows the treats to firm up, making them easier to handle and improving their texture.

7. 7. Serve and Enjoy: Once chilled and firm, your protein snacks are ready to be enjoyed! They’re perfect straight from the fridge.
