Preheat the oven to 350F and grease a 9x13-inch cake pan with cooking spray, or line it with parchment paper. Set aside.
In a large bowl, whisk together the almond flour, cocoa powder, baking soda, baking powder, salt, and monk fruit sweetener.
Make a well in the center of the dry ingredients and add the melted butter, eggs, pumpkin puree, and vanilla. Fold the ingredients in until a super thick batter forms.
Scrape the batter into the prepared baking pan. Grease your hands with cooking spray or oil and press the batter into an even layer in the pan.
Bake in the center rack of the oven for 23-25 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Place the cake on a wire cooling rack to cool completely.
In a large, microwave-safe bowl, add the chocolate chips and coconut cream. Mix together.
Microwave for 15-second intervals, whisking in between until the chocolate and cream are melted and form a smooth, somewhat thick and soupy mixture.
Place the bowl in the fridge and let it sit for 2-3 hours, whisking every 30-50 minutes until the frosting is thickened and a spreadable, fluffy consistency.
Spread the frosting over the cake and decorate, then serve.
