Preheat oven to 350. Grease or use parchment paper in a 13x9 baking dish. Combine walnuts (or pecans or mixture of both) in food processor an blend it until the texture of almond butter. In a large bowl, combine all ingredients (minus chocolate chips), and mix until smooth. Then stir in 3/4 of the chocolate chips. Set aside.
PUMPKIN MIX: 1 can pumpkin puree, 1/3 cup honey, 1 Tablespoon cinnamon, 1 teaspoon baking soda, 1 large egg, 1/4 cup almond flour: combine all and set aside.
Pour 3/4 of the brownie mixture into the pan and spread evenly (this is a very thin layer). Set aside the other 1/4. Take heaping spoonfuls of the pumpkin mixture and place on top of the brownie mixture in the pan until all pumpkin is used. Then add the rest of the brownie mix on top of the pumpkin and run a knife through the top layers making the chocolate and pumpkin swirl, toss the rest of the chips on top and bake 40 minutes or until knife comes out clean from the center.
