I have never bought into the whole “pumpkin” thing but I’ll try anything once.
150g whole wheat flour
150 g flour
1 teaspoon pumpkin spice
1/2 teaspoon baking soda
125g brown sugar
200g butter, chilled and diced
Preheat oven to 350 degrees F. Line and/or butter brownie pan.
Combine flours, oatmeal, pumpkin, baking soda, sugar in food processor.
Pulse a few times to combine everything thoroughly. Add the pieces of butter and pulse until it looks like sandy crumbs.
Remove 4 tablespoons of the crumbs and put them aside. Tip the rest of the mixture into the prepared pan and press down to form a tight even square. Sprinkle the reserved crumbs over the top and bake for 30 minutes. The edges will be slightly browned. Let cool slightly then cut slice down he middle and cut into 14 bars. Let cool completely before removing.
