How to Make Key Lime Protein Bars

1. Pulse the dry ingredients: In a food processor, add the cashews and pulse lightly. Then, add the oats, brown sugar, coconut flakes, chia seeds, flax seeds, protein powder, and salt. Again, pulse together. Finally, add the white chocolate chips and pulse lightly.
2. Add the wet ingredients: In a small bowl, stir together the maple syrup, vanilla, lime zest, lime juice, milk, and coconut oil. Add to the food processor and pulse until the mixture feels wet and sticks together when pressed.
3. Press into a pan: Press oats into a lined 8x8 baking dish, lined with parchment paper. Use fingers and/or the bottom of a measuring cup to press the oats down. If the mixture is too sticky, place in the fridge for 15-20 minutes. Cover and refrigerate for at least one hour. Finally, cut and enjoy!
4. Enjoy and store: Store leftovers in the fridge.
