Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy clean-up.
In a large mixing bowl, combine 1 1/2 cups mashed sweet potatoes, 1/4 cup Tony’s Praline Honey Marinade, and 1 cup cold buttermilk until well mixed.
In another bowl, stir together 3 1/4 cups all-purpose flour, 2 tbsp baking powder, 1/4 tsp baking soda, 2 tbsp sugar, and 1 tsp Tony Chachere’s Creole Seasoning to ensure the leavening agents and spices are evenly distributed.
Grate the 1/2 cup frozen unsalted butter into the flour mixture. Using a fork or pastry cutter, blend until the mixture resembles coarse crumbs.
Gently fold the dry mixture into the sweet potato blend until a soft dough forms. Be cautious not to overmix, or the biscuits could become tough.
Turn the sticky dough onto a well-floured surface, sprinkle with additional flour, and knead it gently about 10 times to form a cohesive dough.
Roll the dough out to about 3/4-inch thick. Use a round biscuit cutter to cut your biscuits, being careful not to twist the cutter to ensure they rise evenly.
Place the cut biscuits on the prepared baking sheet, spacing them about 1 inch apart.
Bake in the preheated oven for 15-20 minutes or until they are golden brown on top. Look for a nice rise and golden colour.
For the Praline Butter Sauce, in a microwave-safe bowl, combine 1/3 cup Tony’s Praline Honey Marinade and 3 tbsp melted butter. Heat in the microwave for 1 minute until warm.
Once the biscuits are out of the oven, brush them immediately with the warm Praline Butter Sauce for a delightful finish. Serve them warm and enjoy!
