The Story Behind This Recipe
This paleo buttermilk chess pie came about because making pie with friends is always a treat. Back in 2020, my sweet friend April and I decided to make a pie together over Zoom – it was all the rage during the pandemic, and a splendid way to stay connected when we couldn’t be in the same kitchen. She had a family chess pie recipe she had enjoyed for years, so we decided to give it a paleo makeover together. And just like that, this recipe was born.
What Is Chess Pie?
If you know, you know. Chess pie is a Southern custard pie – a cousin to pecan pie but without the nuts. It has a rich, silky filling made with eggs, butter, and sugar that bakes up with a slightly crisp golden top. Some versions include cornmeal; April’s family recipe did not, which made the paleo adaptation much more straightforward. Some versions are also lemony, which sounds absolutely wonderful for another day.
Regardless of the variation, chess pie has a rich history and has been a beloved Southern dessert for generations. For many people managing gluten intolerance or dairy allergies, it has been off the table for far too long. So happy to bring it back to your holiday spread.
About the Dairy-Free Buttermilk
Traditional chess pie uses buttermilk for that slightly tangy richness in the filling. To make it dairy-free, simply add one scant tablespoon of lemon juice or apple cider vinegar to a measuring cup, then fill to the 3/4 cup line with almond milk. Stir and let it sit for 5 minutes – it will curdle slightly, just like real buttermilk. That is all it takes, and it works beautifully in this filling.

Ingredients
1 unbaked OG Paleo Cassava Flour Pie Crust
1 1/2 cups maple sugar
1/4 cup cassava flour
1/4 tsp fine sea salt
3 large eggs
3/4 cup dairy-free buttermilk (see notes)
1/4 cup ghee, melted and cooled (or grass-fed butter)
1 tsp pure vanilla extract
dairy-free whipped topping, for serving
garnish of choice (optional)
Directions
- Preheat oven to 350°. Prepare the OG Cassava Flour Pie Crust as directed, finishing the edge as desired. Line a baking sheet with parchment paper and set aside.
- In a medium mixing bowl, whisk together the maple sugar, cassava flour, and salt.
- In a separate bowl, combine eggs, buttermilk, ghee, and vanilla. Mix well with a fork. Pour into the dry ingredients and mix with a hand mixer until the eggs are fully incorporated and the filling is smooth.
- Pour filling into the prepared pie shell. Place on the parchment-lined baking sheet and bake for 45-50 minutes, until the top is golden brown. Cover the crust edge with foil if it begins to get too dark.
- Remove from the oven and cool completely. Before serving, top with dairy-free whipped cream and garnish as desired. Store leftovers in the refrigerator for up to one week.
- To make dairy-free buttermilk: add one scant tablespoon of lemon juice or apple cider vinegar to a measuring cup, then pour in enough almond milk to equal 3/4 cup. Stir and let sit for 5 minutes before using.
