Line a 8x6" (or smaller) baking dish with parchment paper greased with coconut oil

In a large mixing bowl, combine the full batch of granola with melted coconut butter, coconut oil, and collagen. Thoroughly mix until combined

Spoon out the mixture into the baking dish and use a spoon to evenly distribute

Place in the refrigerator for at least two hours

To cut the bars, remove for the fridge and allow to soften for 10-15 minutes. Use a very sharp knife to slice the bars to desired size

For the chocolate drizzle (optional) add the ingredients to a bowl and mixing vigorously. Heat for just a few seconds to soften if needed, but don't allow it to melt.

Pour the frosting mixture into a piping bag or just a bpa free plastic bag with the tip cut off and drizzle over the bars. Top with dried blueberries if desired

Keep the bars in the fridge or freezer and enjoy chilled as a snack or as an addition for a breakfast on the go.
