Step 1

Line an 8x8-inch dish with parchment paper.

Step 2

Combine the oat bar ingredients. Press half of the oat bar mixture into the bottom of the dish and place in the freezer while you make the nutella.

Step 3

Combine all the ingredients for the nutella then spread evenly on top of the first layer of oats.

Step 4

Add back to the freezer for 5-10 minutes then remove and add the rest of the oat mixture on top; spread out evenly. I used a piece of parchment paper sprayed with nonstick cooking spray to help press the top layer down and get it even. The longer you keep it in the freezer, the firmer it gets and the easier it will be to work with.

Step 5

Leave in the freezer for at least 30 minutes before slicing into bars.
