Preheat the oven to 350°F. Grease an 8x8-inch square brownie pan with coconut oil (skip this step if your brownie pan is non-stick).
Mix the dry ingredients in a large mixing bowl: almond flour, oat flour, sugar, arrowroot, baking powder, pumpkin pie spice and sea salt.
In a separate mixing bowl, whisk together the wet ingredients: egg, cashew milk, coconut oil, pumpkin puree and vanilla.
Add the wet ingredients to the dry and stir together until smooth. Then add the chocolate chips and chopped pecans.
Spoon the blondie batter into your prepared pan with a rubber spatula. Spread it out into every corner and smooth the top. Sprinkle more chocolate chips and pecans over top.
Bake for 25 to 30 minutes, until the top is golden and the center is firm. Let it cool completely before removing from the pan, then cut into squares. Eat as-is or serve with non-dairy vanilla ice cream for a decadent treat!
