Perfectly Moist Marble Cake
Ingredients:
| Ingredient | Quantity |
|---|---|
| Semisweet chocolate bar, finely chopped | 113 grams (4 oz) |
| Unsalted butter, softened | ½ cup (113g) |
| Vegetable oil | ½ cup (120ml) |
| Granulated sugar | 1 ¾ cups (350g) |
| Large eggs, room temperature | 4 |
| Vanilla extract | 2 tsp |
| All-purpose flour | 3 cups (375g) |
| Baking powder | 1 Tbsp |
| Salt | ¾ tsp |
| Buttermilk, room temperature | 1 ¼ cups (300ml) |
Instructions:
- Preheat the oven to 350°F and grease and flour your cake pans. Set aside.
- Melt the chocolate in a microwave-safe bowl using 30-second bursts, stirring in between. Continue in 15-second intervals until smooth. Set aside to cool.
- In a large mixing bowl, cream together butter, oil, and sugar with an electric or stand mixer until light and fluffy.
- Add eggs one at a time, mixing well after each addition. Scrape down the bowl as needed and stir in vanilla extract.
- In a separate bowl, whisk together flour, baking powder, and salt. Gradually add the dry mixture to the wet ingredients, alternating with buttermilk, mixing gently with a spatula until just combined.
- Transfer about half of the batter into another bowl and fold in the melted chocolate until fully combined.
- Pour alternating dollops of vanilla and chocolate batter into prepared pans. Use a knife to swirl for a beautiful marbled effect.
- Bake for 30–35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
- Cool in the pan for 10–15 minutes before transferring to a wire rack to cool completely. Slice and enjoy the soft, buttery, and perfectly marbled cake.
