Sweet Potato Buttermilk Pie

Teresa Howell


This sweet potato pie is a pie my aunt always used to make and serve it with vanilla ice cream. A memory that I'll never forget.

Blue Ribbon Recipe

This is a heavenly sweet potato buttermilk pie. It has just the perfect amount of spices and the buttermilk gives the pie a buttery, tangy richness. Serve with freshly whipped cream and a dusting of cinnamon. This pie a sweet and creamy ending to any meal.

Tip: If there isn't enough crust to fold the crust under, just cut off the excess dough before pressing the edges with a fork. Also, make sure to poke holes in the bottom of the crust before pre-baking so the dough doesn't rise. The Test Kitchen
