I found this recipe in the September/October 2020 issue of Bake From Scratch. If you’re not familiar with the magazine, I highly recommend it, the recipes are innovative, delicious, and well tested, and this one is no exception. Made with a simple pound cake recipe, the batter is then divided into three separate bowls, and enhanced with vanilla, chocolate, and dulce de leche. It is then scooped into a loaf pan to create a clever patchwork of flavor.
¾ cup (170 grams) unsalted butter, softened
1½ cups (300 grams) granulated sugar
3 large eggs (150 grams), room temperature
1¾ cups (219 grams) all-purpose flour
½ teaspoon (1.5 grams) kosher salt
¼ teaspoon (1.25 grams) baking powder
½ cup (120 grams) sour cream, room temperature
¼ cup (80 grams) dulce de leche
⅓ cup (57 grams) chopped 60-66% dark chocolate, melted and cooled slightly
1 tablespoon (5 grams) Dutch process cocoa powder
2 teaspoons (8 grams) vanilla extract
1. Preheat oven to 300°F (150°C). Spray an 8½×4½-inch loaf pan with baking spray with flour. Line pan with parchment paper, letting excess extend over sides of pan.
2. In the bowl of a stand mixer fitted with the paddle attachment, beat butter and sugar at medium speed until fluffy, 5 to 6 minutes, stopping to scrape sides of bowl. Add eggs, one at a time, beating well after each addition.
3. In a medium bowl, whisk together flour, salt, and baking powder. With mixer on low speed, gradually add flour mixture to butter mixture in three additions alternately with sour cream, beginning and ending with flour mixture, beating just until combined after each addition. Divide batter into 3 portions (about 1⅓ cups [316 grams] each).
4. In a small microwave-safe bowl, heat dulce de leche for 15 to 20 seconds to soften slightly. Fold into 1 portion of batter. To second portion, add melted chocolate and cocoa, and fold until combined. To remaining portion, add vanilla, and fold until combined.
5. Using 1½-tablespoon spring-loaded scoops, scoop vanilla and chocolate batters in a checkerboard pattern into bottom of prepared pan (5 rows total). Scoop a row of dulce de leche batter down center of pan on top of vanilla/chocolate layer (5 scoops). Tap pan 2 to 3 times to help level batter and fill pan. Create another layer in a checkerboard pattern using dulce de leche and chocolate batters, being sure to place chocolate on top of vanilla batter from first layer. Scoop a row of vanilla batter down center of pan on top of dulce de leche/chocolate layer. Tap pan again. Scoop remaining batter randomly on top. Using a wooden pick, swirl batters together well. Tap pan again to help level batter and fill in any gaps.
6. Bake until a wooden pick inserted in center comes out clean, 1 hour and 40 minutes to 1 hour and 50 minutes. Let cool in pan for 10 minutes. Using excess parchment as handles, remove from pan, and serve warm, or let cool completely on wire rack.
