Chocolate Orange Marble Cake

Ingredients

• 1 3/4 cups (250 g/8.8 oz) all-purpose flour
• 2 teaspoons baking powder
• 1/4 teaspoon baking soda
• 1/4 teaspoon salt
• 1 1/4 cups (250 gr/8.8 oz) granulated sugar
• 2 large eggs (, room temperature)
• 1/2 cup buttermilk or yogurt
• 1/2 cup freshly squeezed orange juice
• 1 tablespoon orange zest ((from oranges))
• 1/4 cup (55 g/2 oz) butter, melted and cooled
• 1/3 cup canola oil ((or vegetable, safflower))
• 1 teaspoon vanilla extract
• 4 oz/113 g bittersweet chocolate (, melted)

Instructions

1. 1

   Preheat oven to 350F/175C. Butter a 9x5-inch loaf pan.

2. 2

   In a large bowl sift together flour, baking powder, baking soda and salt. Add sugar and mix. Set aside.

3. 3

   In a medium bowl, whisk the eggs with the buttermilk, orange juice and zest, melted butter, oil and vanilla. Pour the wet ingredients into the dry ingredients and stir with a wooden spoon or a rubber spatula just until combined. Do not over mix - the less you mix, the lighter the cake will be.

4. 4

   Divide batter into two and fold the melted chocolate to one of the two mixtures.

5. 5

   Dollop the orange and chocolate mixtures alternately into the pan (the post includes a photo to demonstrate it) - first, next to each other (like chess board), then, in layers on top of each other. When done, insert a knife to the mixture all the way down, and start swirling the batter gently, just don’t mix to the point where all the batter turns chocolaty.

6. 6

   Bake for about 45-55 minutes until a toothpick inserted into the center of the cake comes out clean. Let the cake cool for 10 minutes on a wire rack, then turn it out from the pan and let it cool completely.
