Method
- Preheat your oven to 175°C (350°F). Grease your loaf pan and line it with parchment paper for easy removal.
- Using an electric mixer, cream together the butter and sugar until the mixture is light, fluffy, and creamy—about 3-4 minutes. You’ll notice it becomes pale and slightly increased in volume.
- Add eggs one at a time, beating well after each addition to incorporate fully. The batter should become smooth and slightly thicker, with a gentle sheen.
- Mix in the vanilla extract until fragrant—that warm aroma will fill your kitchen.
- Sift together the flour and baking powder, then add to the creamed mixture in three parts, mixing on low speed until just combined. The batter will be thick and smooth.
- Divide the batter evenly into two bowls. To one, gently fold in the sifted cocoa powder, creating a dark, chocolatey batter.
- Alternate spoonfuls of vanilla and chocolate batters into the prepared loaf pan, starting with a scoop of vanilla then chocolate, and so on. Aim for evenly spaced dollops for a striking swirl.
- Use a toothpick or skewer to gently swirl through the batters in a figure-eight motion. Don’t overmix—this creates the beautiful marbled pattern.
- Bake in the oven for 55-60 minutes, until the top is golden and a toothpick inserted in the center comes out with moist crumbs. Cover loosely with foil if the top browns too quickly.
- Allow the cake to cool in the pan for 15 minutes, then transfer to a wire rack and cool completely before slicing. This helps set the crumb and keeps the pattern sharp.
- Slice with a serrated knife to reveal the elegant marbled pattern, and enjoy this rich, tender cake with a cup of tea or coffee.
Notes
Ensure ingredients are at room temperature for the best swirl and crumb. Use a gentle hand when swirling to achieve a striking marble effect. Store leftovers wrapped tightly at room temperature for up to 2 days or refrigerate for up to a week.
