Ingredients You’ll Need
Gathering the right ingredients for this cake is refreshingly simple, yet each one plays a vital role in delivering the perfect taste, texture, and stunning purple hue. From the earthy sweetness of purple sweet potatoes to the tender crumb aided by baking powder, these essentials come together beautifully.
- Purple sweet potato: Provides natural sweetness and a gorgeous purple color without artificial dyes.
- Eggs: Act as a binding agent and add richness to make the cake tender.
- Sugar: Balances the natural sweetness of the potatoes and creates moistness in the crumb.
- Milk: Adds moisture and helps achieve a soft texture.
- Flour: Gives structure to the cake so it holds its shape while remaining light.
- Baking powder: Helps the cake rise and become fluffy.
How to Make Sweet Potato Purple Cake
Step 1: Prepare the Purple Sweet Potato Puree
Start by cooking the purple sweet potatoes until they are tender—steaming or boiling works great. Once soft, mash them thoroughly until smooth and creamy. This puree forms the base of your cake, infusing it with vibrant color and subtle sweetness.
Step 2: Whip Eggs and Sugar
In a bowl, beat the eggs and sugar together until the mixture becomes fluffy and pale. This step adds air to the batter, ensuring your Sweet Potato Purple Cake ends up light and airy instead of dense.
Step 3: Combine Milk and Sweet Potato Puree
Mix the milk with the sweet potato puree and gently fold this into your egg-sugar mixture. Combining these wet ingredients now helps distribute the moisture evenly throughout the cake batter.
Step 4: Fold in Dry Ingredients
Sift the flour and baking powder together to avoid lumps, then carefully fold them into the wet mixture. Be gentle here; overmixing can lead to a tough texture, and you want this cake to be soft and tender.
Step 5: Bake and Cool
Pour the batter into a greased cake pan and bake at a moderate temperature until a toothpick inserted in the center comes out clean, about 40 to 45 minutes. Let the cake cool completely before slicing to preserve its moistness and help it set perfectly.

Make Ahead and Storage
Storing Leftovers
Once cooled, keep any leftover Sweet Potato Purple Cake covered tightly in an airtight container at room temperature for up to two days. This keeps the cake moist without sacrificing its tender crumb.
Freezing
You can freeze this cake by wrapping individual slices in plastic wrap and placing them in a freezer-safe bag. Freeze for up to one month. When ready to enjoy, thaw slices overnight in the refrigerator for best results.
Reheating
Gently warm slices in a microwave for 15 to 20 seconds to bring back the cake’s softness. Alternatively, reheat in a low oven wrapped in foil for 10 minutes to restore its fresh-baked feel without drying out.
