Preheat & Prep: Preheat your oven to 350°F (175°C) and line an 8x8 or 9x13-inch baking dish with parchment paper.

Mix Dry Ingredients: In a large bowl, combine the oats, peanuts, flaxseed, chopped dates, protein powder, and dark chocolate chips.

Mix Wet Ingredients: In a separate bowl, whisk together the honey, melted butter, vanilla extract, milk, and eggs until smooth.

Combine: Pour the wet mixture over the dry ingredients and stir until everything is well coated.

Bake: Press the mixture evenly into the prepared baking dish and bake for 20 minutes, or until the edges are lightly golden.

Cool & Slice: Let the bars cool completely before slicing into squares or bars. Store in an airtight container for up to a week.
