Grease a 9x9 pan with butter or coconut oil
In a medium saucepan, melt the butter.
Add the coconut sugar/Sucanat and vanilla and mix thoroughly.
Mix in oats and coconut and stir until well combined.
Press 1/2 of the oat mixture in bottom of the greased pan and press down.
In another medium saucepan, mix the chocolate chips and peanut or nut butter.
Heat over low heat until chocolate chips have melted, stirring occasionally until the mixture is smooth.
Pour the chocolate mixture over the pressed oat mixture and smooth out with a spoon.
Crumble the other half of the oat mixture over top of the chocolate.
Chill for at least 2-3 hours (preferably overnight).
Bring the bars to room temperature before cutting.
