1. 1. Combine dry ingredients: In a large mixing bowl, add the rolled oats, protein powder, and a pinch of salt. Use a spoon or whisk to thoroughly combine these ingredients, ensuring the protein powder is evenly distributed.

2. 2. Mix wet ingredients: In a separate, smaller bowl, whisk together the nut butter, honey (or maple syrup), milk, and vanilla extract until smooth and well combined. If your nut butter is very thick, you can gently warm it in the microwave for 15-20 seconds to make it easier to mix.

3. 3. Combine wet and dry: Pour the wet ingredient mixture into the bowl with the dry ingredients. Use a sturdy spoon or spatula to mix everything together. Continue mixing until all the dry ingredients are moistened and a thick, uniform dough forms. It might seem crumbly at first, but keep mixing; it will come together.

4. 4. Add optional mix-ins: If you’re using mini chocolate chips or any other desired mix-ins, fold them into the dough now. Distribute them evenly throughout the mixture.

5. 5. Form the treats: Scoop out portions of the mixture (about 1-2 tablespoons each) and roll them into balls. You can also press the mixture into a square pan and cut them into bars later. If the mixture is too sticky, lightly dampen your hands with water before rolling.

6. 6. Chill to set: Place the formed treats on a plate or baking sheet lined with parchment paper. Transfer them to the refrigerator and chill for at least 30 minutes. This chilling time is essential for the treats to firm up and hold their shape.

7. 7. Enjoy: Once firm, your high-protein no-bake treats are ready to enjoy!
