- 1 tsp baking soda
- ½ tsp fine salt
- 2 Tbsp unsweetened natural cocoa powder
- 3 large eggs, room temperature
- 1 cup (240 ml) buttermilk (room temperature)
- ½ cup (120 ml) neutral oil (canola or vegetable)
- 2 tsp pure vanilla extract
- 1 Tbsp white vinegar
- ¾ cup (110 g) fresh or frozen blueberries (cooked down to ≈½ cup strained puree)
- ½ cup (120 g) cooked, peeled, and smoothly mashed purple sweet potato (from 1 medium potato)
- 16 oz (450 g) cream cheese (full-fat and softened but cool)
- 1 cup (225 g / 2 sticks) unsalted butter (softened but cool)
- 5–5½ cups (600–660 g) powdered sugar (sifted)
- 2 tsp pure vanilla extract
- ⅛ tsp fine salt
- 1 Tbsp heavy cream (if needed for consistency) – optional
STEP-BY-STEP INSTRUCTIONS :
-
Prepare the cooked blueberry puree: In a medium-size saucepan, combine the blueberries over medium heat. Cook for 6-8 minutes until the blueberries burst. Mash gently and press through a fine-mesh strainer. Cool completely.
-
Cook the purple sweet potato: Peel and cube one medium-sized purple sweet potato. Boil for 15 minutes until fork-tender. Drain and mash very smoothly. Cool completely.
-
Preheat the oven: Set your oven to 350°F (175°C). Grease three 8-inch round cake pans and use parchment circles to line the bottoms. Dust the insides with flour.
-
Mix the dry ingredients: In a large bowl, combine all-purpose flour, sugar, cocoa, baking soda, baking powder, and salt. Whisk until no lumps remain.
-
Mix the wet ingredients: In another bowl, whisk together eggs, buttermilk, oil, and vanilla. Add vinegar, blueberry puree, and purple sweet potato puree and whisk until smooth.
-
Combine: Pour the wet ingredients into the dry ingredients and mix until just combined. The batter should be thick but pourable.
-
Bake: Distribute the batter evenly in the prepared pans. Bake for 24-28 minutes, rotating pans halfway through. A toothpick should have a few moist crumbs. Cool in the pans for 10 minutes, then turn out onto a rack to cool completely.
-
Make the frosting: Beat butter until super smooth, add cream cheese and beat until fully mixed. Add powdered sugar, vanilla, and salt, mixing on low until incorporated. Increase speed to medium-high and beat until light and fluffy. If too thick, add cream to adjust consistency.
-
Level and stack: Level cake tops if needed. Place the first layer on a cake plate and spread about ¾ cup of frosting on top. Repeat with the second layer, then add the third layer.
-
Crumb coat: Apply a thin layer of frosting around the sides and top of the cake and refrigerate for 20-30 minutes.
-
Final coat: Apply a thicker layer of frosting and smooth it out. Decorate with a star tip and fresh blueberries or edible flowers if desired.
-
Final chill: Refrigerate for 1 hour before slicing.

VARIATIONS
-
Healthier Version: Substitute half of the granulated sugar with a natural sweetener like erythritol or monk fruit sweetener to lower the sugar content. You can also use whole wheat flour instead of all-purpose flour for added fiber.
-
High-Protein or Low-Carb Version: Try swapping all-purpose flour for almond flour and use more egg whites to boost the protein content. For the frosting, consider using Greek yogurt in place of some cream cheese to add protein with fewer calories.
-
Air Fryer or Oven-Baked Version: If you’re short on time, the cake batter can be baked in an air fryer. Fill the air fryer basket with the batter in smaller rounds and bake at 300°F (150°C) for around 20-25 minutes.
