Combine melted coconut oil, coconut sugar, egg, and vanilla in a small bowl. Mix well. Combine almond flour, baking powder, baking soda and salt in a separate bowl and mix together well with a fork. Pour dry ingredients into wet ingredients and mix well with the mixer. Mix in chocolate chips. In a separate bowl, mix together pumpkin mixture.
Line crockpot with parchment paper and add the brownie mix. Drop the pumpkin mixture on top of the brownie mixture in blobs and swirl together using a knife. Place lid on crockpot and cook on LOW for 6 hours or HIGH for 3-4 hours, or until brownies are baked through (this might depend on your crockpot).
To remove, turn crockpot off and lift out carefully using the parchment paper. Let cool and slice.
Makes 16 small brownies or 9 large.
