Chocolate Orange Marble Loaf
≈ 10 servings
Adapted from (original recipe, not yet kitchen-tested)
Ingredients
- 1 3/4 cup 220 g all-purpose flour
- 1 1/2 tsp baking powder
- 1/4 tsp baking soda
- 1/2 tsp salt
- 2 large eggs
- 1 cup 200 g granulated sugar
- 1/2 cup 120 ml neutral oil (canola or sunflower)
- 1/3 cup 80 g sour cream or plain yogurt
- 2 tbsp 30 ml orange zest (from about 2 oranges)
- 1/3 cup 80 ml fresh orange juice
- 1 tsp vanilla extract
- 3 tbsp 15 g unsweetened cocoa powder
- 2 tbsp 30 ml milk (or more orange juice)
- 1/4 cup 45 g mini chocolate chips (optional)
- 3/4 cup 90 g powdered sugar
- 3 tbsp 45 ml fresh orange juice, for the glaze
- 1/4 cup 45 g chocolate chips or chopped chocolate, for the drizzle
- 1 tbsp 15 ml heavy cream or butter, for the drizzle
Method
- Set the oven to 175°C (350°F). Grease the loaf pan and dust it with flour, or line it with parchment paper.
- Whisk together the flour, baking powder, baking soda, and salt in a bowl. Set aside.
- In a large bowl, whisk the eggs and granulated sugar together until smooth and slightly frothy, about 1–2 minutes.
- Whisk in the oil, sour cream, orange zest, orange juice, and vanilla extract until the mixture is uniform.
- Add the dry ingredients and fold with a spatula until just combined — a few streaks of flour are fine.
- Scoop about a third of the batter into a separate bowl. Whisk in the cocoa powder and milk (or extra orange juice) until smooth — the cocoa will thicken it, and the extra liquid brings it back to the right consistency. Fold in the mini chocolate chips if using.
- Alternate dolloping spoonfuls of the orange batter and the chocolate batter into the prepared pan. Once all the batter is in, drag a knife or skewer through it in a swirling figure-eight motion a few times to create a marbled pattern — don't overdo it, or the colors will blend into a uniform brown.
- Bake until a toothpick inserted in the center comes out clean or with just a few moist crumbs — start checking at 45 minutes.
- Let the loaf cool in the pan for 15 minutes, then turn it out onto a wire rack to cool completely before glazing — a warm loaf will just melt everything right off.
- Whisk together the powdered sugar and orange juice until smooth, adding a touch more juice if needed for a pourable consistency. Drizzle over the cooled loaf and let it set a few minutes.
- Melt the chocolate and cream (or butter) together — microwave in short bursts, or a small saucepan over low heat — until smooth. Drizzle over the orange glaze in a crosshatch pattern for the finishing touch.
Notes
- This is a brand-new, untested recipe — the first bake will help dial in the exact timing, the way the other loaves have needed a bake or two to refine.
- Don't overmix the swirl — a few dramatic figure-eight passes with a knife give a nicer marbled look than fully blending the two batters together.
- The chocolate portion is enriched with cocoa and a little extra liquid so it bakes at roughly the same rate as the orange portion — that's what keeps the marbling clean rather than one half over- or under-baking.
- Store covered at room temperature 2–3 days, or in the fridge up to a week; freezes well unglazed.
