Add oat flour, whole wheat flour, salt and baking soda in a bowl and stir.
In another bowl, add softened butter and beat the butter until creamy and smooth. To it add coconut oil, white sugar, brown sugar, egg and vanilla extract. Mix until smooth batter is made.
To it add the dry mix and mix until just mixed.
Fold in ¼ cup chocolate chips.
Cover the bowl with plastic wrap and then place in fridge for 1 hour to overnight.
When ready to bake, let the cold cookie dough thaw for 15 minutes or so.
Preheat the oven to 350F.
Roll cookie dough into 9-10 round balls and place onto a parchment paper lined baking sheet.
Bake for 11 minutes. Let it rest onto the counter and at this stage I add some chocolate chips onto the the just baked soft cookies.
Once completely cool, store in airtight container.
