First, mix your dry ingredients together in a large bowl: flour, brown sugar, pumpkin spice, salt, baking soda, and baking powder.
Next, mix your wet ingredients into the dry ingredients: pumpkin, eggs, chai tea, and butter.
Mix with a hand-held mixer until just incorporated. Do not overmix. The batter will be thick.
Add the mixture to a large piping bag. Clip off the end of the bag where you have a larger opening for the thick batter to come out. (Alternately, you could just spoon the mixture into your donut pan instead of piping) A Ziploc bag works well if you don’t have a piping bag.
Pipe the donut batter into a greased donut pan, If you don’t have a donut pan, you can just make little circles onto a greased cookie sheet. That will work, too!
Bake for 10-12 minutes in a 325-degree oven – when the dough springs back when touched, they are done.
Allow to cool on a wire rack for about 5 minutes. and then dip entire donut into melted butter and then into cinnamon and sugar mixture. Tap off excess and add to the wire rack.
