Step 1

Preheat oven to 350 degrees F (175 degrees C).

Step 2

Grease an 8x8 inch baking pan.

Step 3

In a bowl, stir together the flour, baking powder, and salt.

Step 4

In a separate bowl, stir together the melted butter, sugar, and vanilla. Using a spoon, mix in eggs one at a time. Gradually stir in your flour mixture, and divide the batter evenly amung two separate bowls.

Step 5

Stir in cocoa powder and chocolate chips to one batter. In the second bowl of batter, stir in the pumpkin puree, walnuts, cinnamon, cloves, and nutmeg.

Step 6

Spread 1/2 of the chocolate batter into the bottom of a greased 8x8 baking pan. Spread 1/2 of the pumpkin batter on top of that.

Step 7

Add dollops of each of the remaining batters into the baking pan (this will make it easier to swirl). Then, drag a kitchen knife gently through the dollops of chocolate and pumpkin batter to create a swirled top.

Step 8

Bake at 350 for 45-48 minutes. Enjoy!
