Toast pecans on a baking sheet or in toaster oven for 3-5 minutes, or until fragrant. Be careful, they burn quickly!

Combine wet ingredients (milk, syrup, eggs, coconut oil, vanilla) in another bowl.
Grease a rectangular baking sheet with coconut oil or butter.
Add half the blueberries. Add the dry ingredients. Slowly add the wet ingredients on top. Sprinkle with remaining blueberries and optional coconut sugar.
