Line a muffin pan with cupcake liners, either silicone or parchment paper. Preheat oven to 370.
In a small bowl combine baking soda and apple cider vinegar, mix until it stops fizzing. Set a side.
Pulse the oats in a blender/food processor until finely ground.
To the ground oats add pumpkin spice, baking powder, salt and sweetener. Pulse to combine. Add the rest of the ingredients to the bowl and run it until well combined.
Using an ice cream scoop, fill each cupcake liner 3/4 full. Bake for 20-25 minutes or until a toothpick comes out clean.
