Preheat the oven to 350 degrees. Line a cupcake pan with paper cupcake liners.
Measure ⅓ cup of coconut oil and put it in a small bowl. Microwave for about 15-20 seconds until it is melted. Set aside.
In a large bowl, whisk together the gluten free flour blend, cocoa powder, sugar, baking soda, and salt.
Add the coconut oil, non-dairy milk, vanilla coconut yogurt, vanilla extract, and vinegar, and mix until smooth and combined. (You can use a mixer, or just do it by hand. Either way works).
If the batter seems too thick or dry, add more liquid. Some gluten free flours really soak up the liquid, so adjust the amount if needed.
Spoon the batter into the cupcake liners, filling them about ⅔ full.
Bake at 350 degrees for 19-24 minutes, or until a toothpick inserted inside comes out clean. Place the cupcakes on a wire rack to cool.
Repeat with remaining batter (you will have enough for 2 or 3 more cupcakes).
Once the cupcakes are cool, make the frosting:
Cream the vegan buttery spread in a large bowl. Add a little bit of the sifted powdered sugar and cocoa powder. (To make things easier, I sift these together). Continue to mix on low speed.
Alternate adding the sugar and cocoa powder and drizzling the non-dairy milk in until the desired consistency is reached. The frosting should be thick but spreadable.
Frost the cooled cupcakes, and store in the refrigerator if you are not going to serve them right away.
