Preheat oven to 350 degrees. Line cupcake pans with liners.
In a medium bowl mix together flour, baking powder, baking soda, salt, cinnamon and pumpkin pie spice and set aside.
In a stand mixer fitted with a whisk attachment mix together vegetable oil, eggs, brown sugar, pumpkin puree and vanilla until combined.
Slowly add the dry ingredients to the wet ingredients and mix until fully incorporated.
Fill each cupcake tin 3/4 full and bake for approximately 20 minutes or until a toothpick comes our clean with just a few crumbs.
Allow cupcakes to cool for 5-10 minutes then remove from tin to fully cool.
Once cupcakes are fully cooled, use a pairing knife to cut a small hole in the center of each cupcake about 3/4 of the way down. Fill the hole with approximately 1 tsp apple butter. Top each cupcake with apple butter buttercream.
