Liquid Ingredients
- 7 tablespoons coconut oil (or melted butter)
- 6 tablespoons maple syrup (or honey)

INSTRUCTIONS
Prepare the Wet Ingredients:
- In a medium-sized bowl, combine the coconut oil (or melted butter), maple syrup, peanut butter (or cashew butter), and vanilla extract.

Combine Wet and Dry Ingredients:
- Pour the melted wet ingredients into the bowl with the dry ingredients. Mix well until all the dry ingredients are fully coated with the wet mixture.
Form the Bars:
- Line a baking sheet with parchment paper. Transfer the mixture onto the sheet and spread it out evenly.
- Place another sheet of parchment paper on top and press down firmly to compact the mixture. Use another sheet pan on top to press down if you need. This ensures the cereal protein bars will hold together well.
Bake the Bars:
- Preheat your oven to 300°F (150°C).
- Bake the bars for 20 minutes until they are lightly golden and set.
- Remove from the oven and let them cool completely on the baking sheet.
