- 3/4 cups unsweetened cocoa powder
- 2 tsp baking soda
- 1 tsp baking powder
- 1 tsp fine salt
- 2 large eggs
- 1 cup buttermilk
- 1/2 cup neutral oil
- 2 tsp pure vanilla extract
- 1 cup hot water

STEP-BY-STEP INSTRUCTIONS
- Start by cooking the blueberry puree. Simmer the blueberries over medium heat until they burst. Press through a fine mesh sieve into a bowl and set aside.
- Cook the purple sweet potato in boiling water until tender, then mash it until smooth. Set this aside for later use.
- Preheat your oven to 350°F (175°C) and prepare your three 8-inch round cake pans by greasing them.
- In a large mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt until no lumps remain.
- In another bowl, whisk the eggs, buttermilk, neutral oil, vanilla extract, blueberry puree, and mashed sweet potato until smooth.
- Gradually combine the wet and dry ingredients. Slowly mix in the hot water until the batter is smooth and well combined.
- Distribute the batter evenly into the prepared cake pans. Bake for 24-28 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool for at least 2 hours.
- While the cakes are cooling, make the buttercream. Beat softened butter in a mixing bowl until creamy. Then mix in powdered sugar, heavy cream, vanilla extract, and salt. Stir in the reserved blueberry puree and crushed Oreos.
- Level the cooled cake layers by trimming the tops, if necessary, and stack them with a generous layer of buttercream in between each layer.
- Apply a crumb coat of buttercream around the exterior of the cake to lock in the crumbs. Chill for 20-30 minutes.
- Add a final layer of buttercream around the cake, smoothing it out as you go. Decorate the top with additional crushed Oreos and whole Oreos.
- Chill the decorated cake for at least an hour before slicing and serving.
