Remove plain greek yogurt, eggs, and milk from fridge and let come to room temperature (about 45 min)
1/3 cup plain greek yogurt, 2 eggs, 1/3 cup milk (room temp) + 1 tsp vinegar
Preheat oven to 350°
Add 1 tsp vinegar to milk and stir. Let sit 5 min to become buttermilk.
1/3 cup milk (room temp) + 1 tsp vinegar
Mix flour, salt, light brown sugar, baking soda, baking powder, nutmeg & cinnamon in large bowl.
1.5 cups flour, 3/4 tsp salt, 1/3 cup light brown sugar, 1/2 tsp baking soda, 1 tsp baking powder, 1/2 tsp nutmeg, 1 tsp cinnamon
Mix butter, pumpkin puree, plain greek yogurt, buttermilk, eggs, vanilla, maple syrup in large bowl.
1/4 cup melted butter, 1 cup pumpkin puree, 1/3 cup plain greek yogurt, 1/3 cup milk (room temp) + 1 tsp vinegar, 2 eggs, 2 tsp vanilla, 1 Tbsp maple syrup
Pour wet ingredient mixture into dry ingredients mixture and mix just until combined
Add mixture into a piping bag (you can also use a gallon size ziplock bag). Tip: insert the piping (or ziplock) bag into a large tumbler and pull the edges down around the tumbler. Then add the donut mixture into the bag.
Grease donut pan with non-stick spray (I like avocado oil).
Cut a 2/3 in. hole in the tip of piping bag. Fill each donut cavity about 3/4 the way full.
Bake for about 10 min, until butter knife is inserted into donut and comes out clean.
Remove from oven and cool for 5 min. Then transfer to cooling rack.
Melt butter in shallow dish. Combine cinnamon & sugar for coating in another shallow dish
4.5 Tbsp sugar, 3 tsp cinnamon
Dip each donut in melted butter on both sides. Then dip in cinnamon/sugar coating.
1/3 cup melted butter
Enjoy!
