1. Prepare the Dates: In a food processor, pulse the pitted dates until they form a sticky paste-like consistency.
2. Mix the Ingredients: In a large mixing bowl, combine the rolled oats, protein powder, nut butter, honey or maple syrup, chopped nuts, dried fruits, vanilla extract, and a pinch of salt. Add the date paste to the mixture.
3. Optional Add-ins: If you're including chocolate chips, chia seeds, or coconut flakes, add them to the mixture as well.
4. Combine the Ingredients: Using a spatula or your hands, mix all the ingredients until well combined. The mixture should be slightly sticky but easily moldable.
5. Press into a Pan: Line a square or rectangular baking pan with parchment paper, leaving some overhang for easy removal. Press the mixture firmly into the pan, using your hands or the back of a spoon to create an even layer.
6. Chill: Place the pan in the refrigerator for at least 1-2 hours, or until the mixture is firm and set.
7. Cut into Bars: Once the mixture is set, remove the pan from the refrigerator and lift the bars out using the parchment paper overhang. Place on a cutting board and use a sharp knife to cut into bars of your desired size.
8. Store: Individually wrap the bars in parchment paper or plastic wrap and store them in an airtight container in the refrigerator. They can also be frozen for longer storage.
