Preheat the oven to 325 degrees F and line a baking sheet with parchment paper.
Add all wet ingredients to a large bowl. Mix well. See notes.
Next, add the dry ingredients (except chocolate chips and probiotic powder) to the wet ingredients. Mix well.
Add granola mixture to the baking sheet and press down with a spatula until you have a nice even layer, tightly packed (that's how you get those yummy clusters!)
Bake for 20 minutes on the bottom rack.
Then, take granola out, turn the oven off, flip mixture over and press down again with the spatula into another tightly packed even layer.
Return the granola to the bottom rack and bake for another 15 minutes.
Then, take it out of the oven, and cool the granola cool for about 10-15 minutes. Next, sprinkle chocolate chips over the granola and then return to oven (the oven is still off!) and bake for a minute or two, until the chocolate chips are just starting to melt (soft but not liquid). ***see notes!
Take granola out of the oven and gently mix granola so the melted chocolate spreads a bit.
Let the granola sit and cool and harden.
Add the probiotic powder (sprinkle lightly and evenly) and mix again.
Serve and enjoy! It is best stored in the refrigerator.
