Preheat your oven to 350 degree
Mix together the flour, baking powder, baking soda, pumpkin pie spice, and salt in a bowl
In another bowl combine the sour cream and pumpkin puree
Mix together the butter and sugar in a stand-mixer, or using a hand-mixer, until light and fluffy
Add the eggs to the butter and sugar mixture one at a time and mix until well combined
Mix in the vanilla
Make sure to scrape down the sides if needed
Add in the flour mixture alternating with adding in the sour cream/pumpkin; starting and ending with the flour
Combine until just mixed (being careful NOT to over mix)
Spray two mini muffin tins with cooking spray or brush with oil
Scoop the batter into the muffin tins; only fill about 2/3 of the way to make sure these don’t overflow
Bake for about 8-11 minutes or until the batter has puffed up and is set; careful not to over bake to avoid a dry popper
Mix together the sugar and pumpkin pie spice in a bowl
Pour the melted and cooled butter into another bowl
Allow the poppers to cool enough to be handled
Using a pastry brush to brush the melted butter all over the popper and then roll it in the sugar mixture; if you don’t have a pastry brush you can simply dip them in the butter then roll them in the spiced sugar. Either way your hands are going to get messy… enjoy it!
If the sugar starts to get clumpy from the butter, add in a bit more sugar and spice
Place on a cooling rack
