What You’ll Need
Ingredients:
For the Cake:
- 2 cups all-purpose flour
- 1 ½ teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup granulated sugar
- ½ cup unsalted butter, softened
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup sour cream or Greek yogurt
- ¼ cup milk
- ⅓ cup cocoa powder
- 2 tablespoons hot coffee (or hot water)
For the Cinnamon Streusel (Optional but Recommended!):
- ½ cup brown sugar
- ¼ cup all-purpose flour
- 1 teaspoon cinnamon
- 3 tablespoons cold butter, cut into small pieces
For the Chocolate Drizzle (Optional):
- ½ cup semi-sweet chocolate chips
- 2 tablespoons heavy cream
Tools:
- Mixing bowls
- Electric mixer or whisk
- Measuring cups and spoons
- 9×5-inch loaf pan or bundt pan
- Toothpick for testing
- Wire rack for cooling
Pro Tips
- Use room temperature ingredients to ensure even mixing and a smooth batter.
- Don’t overmix the batter—this helps keep the cake light and fluffy.
- Create perfect swirls by layering the vanilla and chocolate batter, then gently running a knife or skewer through it.
- Add a crunch! The streusel topping adds texture and extra cinnamon flavor.
- Let the cake cool completely before adding the chocolate drizzle to prevent melting.
Substitutions and Variations
- Make it dairy-free: Swap butter for coconut oil, use dairy-free yogurt, and almond milk instead of regular milk.
- Gluten-free option: Use a 1:1 gluten-free flour blend in place of all-purpose flour.
- Extra chocolatey: Fold in ½ cup of chocolate chips into the batter before baking.
- Nutty twist: Add ½ cup of chopped walnuts or pecans for an extra crunch.
How to Make It
1. Prepare the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
2. Mix the Wet Ingredients
In a large mixing bowl, beat the butter and sugar together until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract, sour cream, and milk until fully combined.
3. Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Be careful not to overmix.
4. Make the Chocolate Batter
In a small bowl, mix the cocoa powder and hot coffee (or hot water) to form a smooth paste. Take half of the cake batter and mix it with the cocoa mixture, creating the chocolate portion of the batter.
5. Create the Marble Effect
Grease and flour a 9×5-inch loaf pan or bundt pan. Alternately spoon the vanilla and chocolate batters into the pan. Use a skewer or butter knife to gently swirl the batters together, creating a marbled effect.
6. Add the Streusel (Optional)
If using the cinnamon streusel, mix brown sugar, flour, and cinnamon in a bowl. Cut in the cold butter with a fork or your fingers until crumbly. Sprinkle evenly over the batter.
7. Bake the Cake
Preheat your oven to 350°F (175°C). Bake for 45-55 minutes or until a toothpick inserted into the center comes out clean. If using a bundt pan, baking time may vary slightly.
8. Cool and Drizzle (Optional)
Let the cake cool in the pan for 10 minutes before transferring to a wire rack. If adding the chocolate drizzle, melt the chocolate chips and heavy cream together in the microwave in 15-second intervals, stirring until smooth. Drizzle over the cooled cake.
Leftovers and Storage
- Store in an airtight container at room temperature for up to 3 days.
- Refrigerate for up to a week and warm slices before serving.
- Freeze for up to 3 months. Thaw overnight in the fridge before enjoying.
