In a medium bowl, whisk together the sifted gluten-free flour, cocoa powder, and psyllium husk powder until completely mixed and one color.
Add the oil and milk and stir with a fork just until it comes together in a ball, use a spatula to finish mixing to ensure there is no dry mixture underneath.
Set aside to rest while making the filling. You'll be using a 9-9-1/2 inch (20-25 cm) pie pan. You don't need to prepare the pan, although lightly greasing it with coconut oil is fine.
Filling
Preheat oven to 400F/200C/gas mark 6.
In a high-speed blender, mix all the filling ingredients except the chocolate chips until perfectly smooth, stopping to scrape down the sides as needed. I use my Vita-mix tamper for this.
Pour in half the filling, then sprinkle evenly with the chocolate chips. Pour in the rest of the filling, using a thin spatula to get as much as possible out of the blender. Smooth the top with the spatula.
Bake for ten minutes, then turn the oven down to 350F/180C/gas mark 4 and bake for 25-30 minutes or until the edges are browned and the top has started to crack. It will still be fairly jiggly and will set up more as it cools.
Cool on a wire rack, then top with vegan whipped cream if desired.

For a less-sweet pie, use the smaller amount of chocolate chips. You can also mix the chips evenly throughout the filling, although I liked them as a layer in the middle. I used Bob's Red Mill Gluten-Free All-Purpose Making Mix, which includes tapioca starch and garbanzo bean flour, but does not include xanthan gum. If your gluten-free mix contains xanthan gum, omit the psyllium husk powder. If you do not have access to a gluten-free baking mix, use: 1/4 C. each tapioca flour, garbanzo bean flour, sorghum flour, brown rice flour. If your gluten-free flour mixture contains only tapioca starch and rice flour, use 2/3 C. of that and 1/3 C. garbanzo bean flour.
