🧾 Ingredients for Marble Loaf Cake

Dry Ingredients:

  • 2 cups all-purpose flour
  • 2 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt

Wet Ingredients:

  • ¾ cup butter (softened) or oil (for extra moisture)
  • 1 cup sugar
  • 3 large eggs
  • 1 cup milk (or buttermilk for a softer texture)
  • 1 tbsp vanilla extract

Chocolate Batter:

  • ¼ cup cocoa powder
  • 2–3 tbsp milk (to loosen the batter)

👩‍🍳 How to Make Chocolate Marble Loaf Cake

1. Prep the Oven

Preheat oven to 170°C (340°F). Grease and line a loaf pan.

2. Mix Dry Ingredients

In a bowl, whisk together flour, baking powder, baking soda, and salt.

3. Cream Butter & Sugar

Beat butter and sugar until light and fluffy. This step helps create a soft, airy cake.

4. Add Eggs

Add eggs one at a time, mixing well after each addition.

5. Add Liquid Ingredients

Mix in milk and vanilla extract until smooth.

6. Combine Batter

Gently fold in the dry ingredients. Avoid overmixing to keep the cake tender.

7. Divide & Flavor

Split the batter into two bowls.
Mix cocoa powder and milk into one portion to create the chocolate batter.

8. Create Marble Effect

Alternate spooning vanilla and chocolate batter into the pan.
Use a knife or skewer to gently swirl for a marble pattern.

9. Bake

Bake for 50–60 minutes or until a toothpick inserted comes out clean.

10. Cool

Let the cake rest before slicing—this helps retain moisture and improves texture.


⭐ Tips for a Perfect Marble Cake

  • Use oil instead of butter for extra moisture
  • Don’t over-swirl or the marble pattern will disappear
  • Use room temperature ingredients for a smooth batter
  • Let the cake cool completely before cutting clean slices
