You must first prepare the Snickerdoodle Apple Pie Bites in advance before preparing the cupcake batter *minus the crumb topping & sugar glaze
Once they are baked & cooled place them in the freezer while you gather your ingredients to prepare the recipe for the pumpkin cake
Preheat your oven to 350°F & line your cupcake pans with paper liners (I also like to give them a very light spray with pan release to make sure they don't stick to the wrappers)
For the cake batter, combine the vinegar with the plant milk (soy milk is the only milk that will thicken with vinegar)
In a large mixing bowl combine the oil, brown sugar, salt, pumpkin then the thickened vinegar/plant milk & whisk to combine well
Sift the flour with all the spices and the baking soda and add it all at once to the wet mixture in the bowl and whisk smooth by hand
Portion into the cupcake liners, filling slightly less than 3/4 of the way full
Place a frozen mini snickerdoodle apple pie into the center of each one, pushing it into the batter slightly
Bake immediately in the preheated 350°F oven for 15 minutes
Then turn the oven temperature down to 300°F and bake for another 8-10 minutes OR when a toothpick inserted into the center comes out clean
Cool the pumpkin cupcakes in the pan until you can touch it without burning your fingers, then turn them out onto a cooling rack to cool all the way
Prepare your favorite buttercream recipe *I am using American Style Buttercream* and at the last stage of mixing add the pumpkin & the spices
