Loving These Sweet Potato Biscuits
We are just loving this from scratch sweet potato biscuit recipe, and I know you will as well. These homemade skillet biscuits are easily made with simple, familiar ingredients you probably already have on hand.

Ingredients for Sweet Potato Biscuits
Here is what you will need to make sweet potato biscuits with a few tips and variations if needed:
- Sweet potato– you will need 1 cup of cooked sweet potato. Bake the sweet potato in the oven or poke a few holes in the potato with a fork and microwave for 3-5 minutes until a fork slides easily into the flesh. Cut it in half and scoop out the potato.
- All purpose flour– or a 1:1 ratio gluten free flour if you want to make these gluten free.
- Baking powder– doing the heavy lifting to make these biscuits fluff up and stand tall.
- Brown sugar– add just a touch of sweetness that gives these biscuits a little extra flavor. Honey can also be used.
- Butter– I prefer to bake with unsalted butter so I can adjust the salt as needed. Make sure it is cold.
- Buttermilk– helps activate the baking powder for fluffy biscuits. Substitute 1/2 cup milk plus 1 teaspoon vinegar/lemon juice for buttermilk if needed.

How to Make Sweet Potato Biscuits in a Cast Iron Skillet
Let’s walk through the simple steps to make sweet potato biscuits in a cast iron skillet. Full details can also be found in the recipe card at the bottom of this post.

- Mash sweet potatoes– to get the cooled sweet potatoes to the right consistency for biscuits, we are going to place them in a food processor or blender with the buttermilk and pulse until a smooth paste-like texture is formed.
- Mix the dry ingredients– in a large mixing bowl, whisk together the flour, baking powder, salt and brown sugar until combined.

- Cut in the butter– make sure your butter is cold and, using a cheese grater, cut the butter into the flour mixture and toss to coat.
- Bring the dough together– add the sweet potato puree into the dry ingredients and using a wooden spoon or spatula scrape the sides towards the center to bring the dough together. Mix as well as you can with the wooden spoon, then with clean hands, knead the dough to mix it all together into a rough ball shape.

- Roll out and cut the biscuits– (see video below) on a lightly floured surface press or roll the dough out into a rectangle, fold one side over to the other and roll out again. Roll and fold 4 times before rolling the dough out to about 1/2 inch thick. Cut with a 3 inch round cookie cutter, biscuit cutter, or even a drinking glass.

- Bake– evenly place the biscuits into a greased or well seasoned 12 inch cast iron skillet. Bake in a 425º F oven for 15-20 minutes, until golden brown and baked through. Brush with honey butter while still warm if desired.
Tips For Making The Best Sweet Potato Biscuits
These biscuits are super easy to make, but here are my tips to make sure they come out perfect every time.
- Use cold sweet potatoes– biscuits bake up better if all of the butter and buttermilk stay nice and cold, so place the sweet potato in the freezer or fridge to cool or make the night before you want to bake these biscuits to be sure the potatoes are cold.
- Avoid overworking the dough– use a light touch when folding and rolling out the dough to help keep the biscuits soft. Overworking the dough can make tough biscuits.
- Pay attention to the dough texture– the dough should be like the texture of Playdough, not too soft and not sticky.
- Use the right skillet– these are baked in a 12 inch cast iron skillet, it is NOT preheated before adding the biscuits. Only add butter or grease in a very thin layer if needed.
- Know when they are done– they will be slightly golden on top and puffed up with flaky layers. You can also measure the temperature in the center of the biscuits with an instant read thermometer to check for doneness. It should read 120º F.

Recipe FAQs
When I make these ahead, I like to roll them out and cut them into biscuits, then before baking, place them on a parchment lined baking sheet and freeze for 30 minutes until frozen. Then place into a zip top bag or air tight container until ready to bake. Bake until golden brown from frozen, it can take a few more minutes.
Biscuits become dense when they are overworked before baking, so just be careful not to over knead the biscuit dough.
If you don’t own a 12 inch cast iron skillet, these sweet potato biscuits can be baked on a baking sheet lined with parchment paper or lightly greased.
