WHY YOU SHOULD MAKE THIS RECIPE
- You can make this marble loaf cake with one batter, so it’s surprisingly easy and requires minimal effort.
- The marble pattern in the finished cake looks amazing and adds a unique twist on traditional marble cake.
- This marble loaf cake is moist, flavorful, and incredibly delicious!
- Butter & Vegetable Oil – Using both butter and oil helps keep the cake moist and give it a great texture. The butter needs to be at room temperature to cream well. If you forgot to leave it out, learn how to soften butter quickly.
- White Granulated Sugar – Adds sweetness to the cake.
- Eggs – Helps enrich the batter with even more moist texture and helps the cake set while baking.
- All-Purpose Flour – Adds structure and stability to the marble loaf cake.
- Baking Powder & Baking Soda – Assists with the rise of the marble loaf cake to make it fluffy while staying dense and rich.
- Kosher Salt – Gives the loaf cake a boost of flavor and helps balance out the sweetness.
- Vanilla Extract – Provides a delicious background flavor to the marble loaf cake.
- Unsweetened Cocoa Powder – Used for the chocolate marble effect that gives it a classic swirl look. Use Hershey’s Special Dark to make the chocolate stand out even more.
- Buttermilk – Unlike regular milk, buttermilk gives the marble loaf cake a unique tanginess and helps give it a moist and tender crumb.
- Chocolate frosting- Optional! You can top it with this brownie frosting or this small batch chocolate buttercream.
You’ll need a standard size loaf pan too. A standard size is around 9 “x 5 ” like this loaf pan.
HOW TO MAKE MARBLE LOAF CAKE
Prep to bake– Preheat the oven to 350 F. Heavily spray a loaf with baking spray. Set aside.
Cream the butter and sugar: Add the butter and sugar into the bowl of a stand mixer with the paddle attachment. Mix on low speed, then add the vegetable oil and eggs one at a time, mixing in between each ingredient.
Combine other ingredients: In a separate bowl, add the flour, baking powder, baking soda, and kosher salt. Whisk until fully combined. In a separate mixing bowl, whisk the buttermilk and vanilla together.
Mix wet and dry ingredients: Add the dry ingredients to the wet ingredients, slowly alternating each until the batter is just combined.
Make the chocolate batter: Remove 3/4 cup of the batter and whisk it with the cocoa powder and the rest of the buttermilk.
Assemble the marble loaf: Pour a thin layer of the vanilla batter into the bottom of the loaf pan, then alternate, adding each batter with an ice cream scoop until all of it is in the pan. Use a skewer or knife to swirl the batter together, making sure not to over-swirl.
Bake- Bake the loaf cake for 50-55 minutes or until a skewer is inserted into the middle of the cake and comes out with only a few loose crumbs. Cool.
This loaf cake doesn’t need any topping but you can sprinkle with confectioners sugar, or make this small batch chocolate buttercream.
TIPS FOR RECIPE SUCCESS
- When scooping the batter alternate the vanilla and chocolate on top of each other. It doesn’t have to be perfect!
- Make sure your butter and eggs are at room temperature before beginning, as this will lead to a smooth and even batter.
- When you’re at the swirling stage, don’t overmix the batter for marble effect, otherwise, you won’t get that marble pattern, and the cake will become a light brown color.
- Let the marble loaf cake cool completely before adding any toppings or drizzle, as a warm cake will melt any topping you place on top.
- For best results, use Hershey’s Special Dark cocoa powder, so the chocolate really stands out.
STORAGE AND FREEZING
Storing: Once frosted and cooled, a marble loaf cake can be stored in an airtight container for up to 3 days on the counter. It can also be stored in the fridge for up to 5 days. Beware though that the fridge can turn a cake dry faster because of the cold air.
Freezing: You can also freeze marble loaf cake for up to 3 months! To do this, wrap it tightly in a few layers of plastic wrap followed by aluminum foil, and place it in a freezer bag. Thaw on the counter before serving.
Is marble loaf cake difficult to make?
No, marble cake is relatively easy to make with one batter. The key is to not over-mix the marble effect and let it cool fully before adding any toppings or drizzle.
Can I use a hand mixer instead of a stand mixer?
Yes, a hand mixer can be used instead of a stand mixer, just be sure to not overwork the batter as it may become too tough.
What other variations or substitutions can I make?
Besides using dark Hershey’s cocoa powder for a dramatic marble pattern, you can also use different flavor extracts like almond extract or orange extract instead of vanilla extract. You can also use melted and cooled coconut oil instead of vegetable oil for a light coconut flavor.
WAYS TO ENJOY
- Enjoy a warm slice with a scoop of vanilla ice cream for dessert.
