Chocolate Blueberry Roulade Torte

Ingredients

• 1 cup unsalted butter (2 sticks), cut into pieces, plus more for the pans
• 2 cups all-purpose flour, spooned and leveled
• 1 1/2 cups granulated sugar
• 3/4 cup unsweetened cocoa powder
• 1/2 cup dark brown sugar
• 1 teaspoon baking soda
• 1 teaspoon kosher salt
• 2 large eggs
• 1/2 cup sour cream
• 1 teaspoon pure vanilla extract

Directions

1. Heat oven to 350º F. Butter two 8- or 9-inch round cake pans and line the bottom of each with a round of parchment paper.
2. In a large bowl, whisk together the flour, granulated sugar, cocoa powder, brown sugar, baking soda, and salt.
3. In a small saucepan, combine the butter and 1 cup water and bring to a boil. Add to the flour mixture and, using an electric mixer, mix until combined. Beat in the eggs, one at a time, then the sour cream and vanilla.
4. Divide the batter evenly between the prepared pans. Bake until a toothpick inserted in the center of each cake comes out clean, 35 to 45 minutes. Cool in the pans for 20 minutes, then turn out onto a rack to cool completely.
