This sweet potato pie pound cake with cinnamon glaze ain’t playing around, boos! It’s a mix of my bomb sweet potato pound cake and my Big Mama’s famous sweet potato pie. The result is a sweet potato pie pound cake so tender and full of flavor that it just feels like home. Now, before y’all side-eye that long recipe card, hear me out! It’s mostly me explaining how to layer the cake. Nothing crazy. I even showed y’all how to cook the sweet potato, so my first-timers are set. Grab that Bundt pan and get into it.

How to Make Sweet Potato Pie Pound Cake
Prep the Crust

Step 1: Preheat the oven and line a sheet pan with parchment. Unroll the pie crust, bake until lightly browned, then brush with butter and sprinkle with sugar and cinnamon. Bake again until golden and fragrant.

Step 2: Remove from the oven and set aside to cool completely. Once cooled, break into medium pieces and divide into fourths.
PRO TIP: You can totally use store-bought pie dough for this recipe, but I highly suggest making my homemade pie crust. Once you try it, you’ll never go back to the packaged stuff!
Make the Sweet Potato Filling

Step 3: Prick the sweet potato all over and microwave until tender. Let cool slightly, peel off the skin, and measure out one cup of mashed potato. (If you have extra, reserve for another use. Like my sweet potato pie cookies!)

Step 4: Place the potato in a medium bowl and mash with a fork and stir in the butter until melted. Whisk in the sugar until dissolved. Next, whisk in the milk, yolk, and salt. Set aside. Once cool, place the mixture in a pastry bag or a large zip-top bag.
Mix the Cake Batter

Step 5: In a stand mixer with the whisk attachment, beat the butter and both sugars until light and fluffy. Add the eggs one at a time, mixing well, then reduce speed and mix in the flour, salt, baking powder, baking soda, cinnamon, and nutmeg just until combined.

Step 6: Add sour cream and vanilla and mix on low until everything is just combined. Scrape down the sides and bottom of the bowl to ensure everything is mixed evenly.
Assemble the Layers and Bake

Step 7: Lower the oven temperature and coat a Bundt pan with nonstick spray or my homemade cake release. Sprinkle one-fourth of the pie crust pieces into the bottom of the pan.

Step 8: Alternate dollops of one-third of each of the cake batter and sweet potato filling on top and swirl gently with a toothpick. Try not to disturb the pie pieces.

Step 9: Sprinkle on another fourth of the pie crust pieces.

Step 10: Pipe on the next third of sweet potato filling and spread evenly with a spatula.

Step 11: Pour on the next third of cake batter and make even. Then, sprinkle on another fourth of the pie crust pieces. (You should still have the last fourth of pie pieces.)

Step 12: Pipe on the last third of sweet potato filling.

Step 13: Pour on the last third of cake batter.

Step 14: Bake the cake until a skewer comes out with moist crumbs, then let it cool briefly in the pan before inverting onto a platter to cool completely.
Glaze It Up!

Step 15: Whisk the powdered sugar, salt, and cinnamon in a small bowl, then add milk and vanilla, mixing until smooth and glossy.

Step 16: Pour the cinnamon glaze on top and let it drizzle down the sides. Top with the remaining pie pieces and let the glaze set. Slice, serve, and enjoy!

- 3 cups cake flour sifted
- 1 teaspoon kosher salt

For the Cinnamon Vanilla Glaze
- 1 ½ cup powdered sugar
- Pinch kosher salt
- 1/8 teaspoon ground cinnamon

Instructions
For the Crust
- Preheat the oven to 350°F and line a sheet pan with parchment paper. Gently unroll the thawed pie crust into a complete circle and place on the lined pan. Bake for 10 minutes, until lightly browned. Remove from the oven and brush on the butter and sprinkle on the sugar and cinnamon. Return the oven for an additional 3-4 minutes until the crust is golden brown and the cinnamon is fragrant. Remove from the oven and set aside to cool completely. Once cooled, break into medium pieces (about 1 inch in size) and divide into fourths.
For the Potato
- Using a fork, prick the sweet potato 8 times around the entire surface and place the potato on a microwave-safe plate. Cook in 3 minute intervals until a toothpick can be inserted into the potato with no resistance, about 8-9 minutes.
- Remove the potato from the microwave and cool for 10 minutes. While still warm, carefully remove the skin from the potato and discard it. (You should have 1 cup of potato. If you have extra, reserve for another use.)
- Place the potato in a medium bowl and mash with a fork and stir in the butter until melted. Whisk in the sugar until dissolved. Next, whisk in the milk, yolk, and salt. Set aside. Once cool, place the mixture in a pastry bag or a large zip-top bag.
For the Cake
- Reduce the oven to 325° and prepare a 14-cup Bundt pan by spraying liberally with nonstick baking spray or by brushing with my Homemade Cake Release.
- In the bowl of your stand mixer fitted with the whisk attachment, add butter and both sugars. Beat on high for about 6 minutes, until light and fluffy.
- Reduce the speed to medium and add eggs one at a time, mixing well after each addition, and scraping down the sides and bottom of the bowl.
- Reduce the speed to low and slowly add the flour, salt, baking powder, baking soda, cinnamon, and nutmeg. Mix until just combined. Do not over mix here.
- Add sour cream and vanilla and mix on low for 30 seconds until everything is just combined. Scrape down the sides and bottom of the bowl to ensure everything is mixed evenly.
To Assemble
- First layer: Sprinkle one fourth of the pie crust pieces on the bottom of the prepared Bundt pan. Next, alternate dollops of one-third of each the cake batter and sweet potato filling on top and swirl gently with a toothpick. Try not to disturb the pie pieces.
- Second layer: Sprinkle on another fourth of the pie crust pieces. Pipe on the next third of sweet potato filling and spread evenly with a spatula. Then, pour on the next third of cake batter and make even.
- Third layer: Repeat steps for the second layer. (You should still have the last fourth of pie pieces.) Gently tap the pan on the countertop to allow all the layers to settle.
- Place the cake in the oven and bake until a skewer inserted comes out with several moist crumbs attached, about 1 hour 5 minutes.
- Remove the cake from the oven and let cool in the pan for 15 minutes. Invert the pan onto a serving platter and allow to cool completely, about 1 hour.
For the Glaze
- While the cake is cooling, add the powdered sugar, salt, and cinnamon in a small bowl and whisk together.
- Add the milk and vanilla extract and whisk until smooth and glossy.
- Once the cake is completely cool, pour the glaze on top and let it drizzle down the sides. Top with remaining pie pieces and let the glaze set for 5 minutes. Slice, serve, and enjoy!
Notes
How to Store
- Room Temp: Keep your sweet potato pound cake with glaze covered in an airtight container on the counter for up to 3 days.
- Fridge: You can pop it in the fridge for up to a week. Place a piece of parchment or wax paper between the glaze and the lid so it doesn’t stick.
- Freezer: Wrap slices tightly in plastic wrap, then foil, and freeze for up to 3 months. If you’re freezing the whole cake, use that parchment trick under the lid again to keep the glaze from gluing itself on. Thaw overnight in the fridge before serving.

Recipe Tips
- Pick the right sweet potato. Go for ones that are firm with smooth skin and no bruises or soft spots. I like the small to medium ones since they have fewer stringy bits and make a smoother filling.
- Mash it while it’s still warm. That way, the butter melts right in and gives your cake the creamiest texture.
- Make layering easy on yourself. If you stored your sweet potato filling in a zip-top bag, just snip the tip and pipe it straight into the pan when layering the cake.
- Grease your Bundt pan well. Get into every little nook and cranny before adding the batter.
- DON’T overmix the batter! It’s a sweet potato swirl pound cake, so we gotta keep it as tender and moist as possible.
