In a large bowl, combine the pumpkin puree, melted vegan buttery spread, and sugar.
Add the gluten free flour blend, oat flour, baking soda, salt, cinnamon, ginger, nutmeg, cloves, vanilla, vinegar, and water. Stir well until smooth and combined.
Spoon the batter into the cupcake liners, filling them about ⅔ full.
Bake at 350 degrees F for about 22-25 minutes, or until a toothpick inserted in the center of the cupcakes comes out clean.
Once the cupcakes are cool, make the frosting.
Beat the buttery spread until fluffy, then add one cup of powdered sugar. and drizzle in a little water. Mix on medium speed, alternating between adding more sugar and water until the frosting is thick and creamy. Add the spices and mix again.
Spread or pipe frosting onto cooled cupcakes. I used a Wilton 1M icing tip to pipe the frosting on.
Notes
Store leftover cupcakes in an airtight container at room temperature for up to 3 days.If you want to keep them for longer, I recommend storing them in the refrigerator.
