Preheat oven to 350 degrees. Grease a 9″ square cake pan.
Cream the butter and sugars together, and add the egg and vanilla, stirring until smooth.
Add the flour, 1 1/2 cups Rolled Naked Oats, baking powder, and salt.
Press 2/3 of this mixture into the bottom of the cake pan. Add the remaining 1/4 cup rolled oats and 1/4 cup chopped hazelnuts to the flour mixture that is left in the bowl, so that it is now quite crumbly. Set this aside, as it will be used for the top layer.
In a small saucepan, melt the chocolate and butter over a low temperature. Add 1/2 cup chopped hazelnuts, and spread the chocolate-y goodness over the bottom layer.
Pit your cherries, keeping all the juice together with the fruit. Add the chia seeds, and let them sit together for about 10 minutes until the chia seeds have absorbed most of the liquid, and the resulting ‘jam’ is nice and thick. Spread the cherries over the chocolate mixture.
Finally, crumble the last of the flour mixture over the cherries, and press down gently.
Bake for about 30 minutes, or until the crumbs are just starting to turn golden brown. Cool for at least an hour before slicing into squares.
