Potato Doughnuts

This is my mom's Potato Doughnut recipe. They are not overly sweet. I made a half batch on Saturday. Yum!
Makes about 42 doughnuts and doughnut holes

Combine in a large bowl:
1 cup mashed potatoes
2 Tbsp. yeast
1 1/2 cup very warm water
1 1/4 tsp. Salt
1 cup sugar

Stir until dissolved, let stand 20 minutes until bubbly.

Stir in 2 beaten eggs, 2/3 cup softened butter. Add 6 1/2-7 cups of flour, 1 cup at a time, stirring well after each addition. Knead last portion of flour in. Let stand (covered) until more than doubled.

Stir down; divide in half. Roll about 3/8” thick, cut.


Cover and let rise.


Fry in hot oil, puffy side down first. Drain on toweling.

Add 1/4 cup hot water to 1/2 cup powdered sugar and 1/4 tsp. Vanilla to make glaze. Dip doughnuts in glaze while still hot.
