I have a soft spot for marble cake. The moment you slice through its gleaming, swirled top and see the ribboned vanilla and chocolate crumb, it feels like a small celebration. I remember making this on a rainy afternoon and the kitchen smelled like toasted cocoa and warm vanilla, and that first forkful was all flaky crumbs and melt-in-your-mouth buttercream bliss. If you want a dependable cake that looks fancy with very little fuss, this is your recipe — and if you like, you can compare techniques on a classic marble cake page I turn to for inspiration.
Why Marble Cake Belongs in Your Baking Rotation
- Visual drama without being difficult: the marbling looks like you spent hours decorating, but it is simply a swirl away.
- Crowd-pleasing flavor duo: vanilla and chocolate play off each other in every bite, giving a lovely balance of sweetness and cocoa depth.
- Friendly to bakers of all levels: the method is straightforward, great for beginners and fun for seasoned bakers who want quick satisfaction.
- Versatile for occasions: dress it up with glossy buttercream for birthdays or serve plain for tea time and nobody will complain.
- Keeps and freezes well: it holds its texture, which means you can plan ahead and still enjoy a fresh slice later.
Ingredients You’ll Gather
Below is everything you need, with quick notes on why each item matters.
- 2 1/2 cups (325g) all-purpose flour, spooned and leveled — the cake’s structure. Spoon and level to avoid a dense loaf.
- 2 tbsp cornstarch — lightens the crumb so the cake is tender, not cakey.
- 2 tsp baking powder — provides lift so your cake rises evenly.
- 1/2 tsp baking soda — works with the vinegar and buttermilk-like mix for a lighter texture.
- 1/2 tsp salt — balances sweetness and enhances flavor.
- 1 1/2 cups (360mL) milk, room temp — keeps the batter smooth and adds moisture.
- 1 1/2 tbsp white vinegar — turns milk into a quick sour-milk substitute for tenderness.
- 1/2 cup (115g) unsalted butter, room temp — richness and flavor; unsalted gives you better control of salt.
- 1/3 cup (80mL) vegetable oil, or any neutral flavored oil — adds moistness and keeps the cake soft the next day.
- 1 1/2 cups (300g) granulated sugar — sweetness and helps with browning.
- 3 large eggs, room temp — structure and emulsification; room temperature eggs mix more evenly.
- 2 tsp pure vanilla extract — brightens and rounds all flavors.
- 1/4 cup (20g) unsweetened cocoa powder — for the chocolate swirl.
- 1 tsp black cocoa powder (optional)* — for an extra deep, almost ebony chocolate ribbon.
- 5 tablespoons whole milk, room temp — used in the frosting to adjust consistency.
- 1 1/2 cups (340g) unsalted butter, room temp — the base of the buttercream for a silky finish.
- 4 cups (520g) powdered sugar, sifted — sweetness and stability for the frosting.
- 1 cup (80g) unsweetened cocoa powder, sifted — chocolate flavor in the buttercream.
- pinch of salt — balances the sweetness of the frosting.
- 3-4 tbsp milk — to thin the buttercream to spreadable perfection.
- 1 tsp pure vanilla extract — adds warmth to the chocolate buttercream.

Let’s Get Swirling: Step-by-Step Directions
Ready? Take a breath, preheat your oven, and enjoy the rhythm of measuring, mixing, and swirling. Below are clear, numbered steps for both the cake and the chocolate buttercream.
Marble Cake:
- Preheat the oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan or line with parchment.
- In a medium bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt; set aside.
- Combine the 1 1/2 cups milk with the 1 1/2 tablespoons white vinegar and let sit 5 minutes to curdle into a quick buttermilk.
- In a large bowl, beat the 1/2 cup butter, 1/3 cup oil, and 1 1/2 cups sugar until light and fluffy, about 2-3 minutes. Add eggs one at a time, beating after each addition, then stir in the vanilla.
- Add the dry ingredients to the wet in three additions, alternating with the curdled milk, beginning and ending with the dry ingredients. Mix until just combined; do not overmix.
- Scoop about two-thirds of the batter into another bowl. Stir the 1/4 cup cocoa powder and optional black cocoa into the reserved portion until evenly chocolate.
- Spoon dollops of vanilla and chocolate batter alternately into the prepared pan, then run a knife through the batter in a figure-eight pattern to create swirls.
- Bake for 50-60 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Let cool in the pan 10 minutes, then transfer to a wire rack to cool completely.
Chocolate Buttercream:
- Beat 1 1/2 cups butter on medium speed until creamy, about 2 minutes.
- Gradually add sifted powdered sugar and sifted cocoa, alternating with 5 tablespoons milk, beating well after each addition. Add a pinch of salt and 1 teaspoon vanilla.
- If too thick, add an extra tablespoon of milk at a time until you reach a spreadable frosting. Chill briefly if too soft before spreading.

Pro Tips I Swear By
- Always bring eggs and milk to room temperature; they incorporate more smoothly and give you a tender crumb.
- Do not overmix after adding flour; overworked gluten means a tough cake. I gently fold in the last bits by hand.
- For dramatic marbling, layer batters in thick dollops and swirl with a wide, sweeping motion rather than tiny circles.
- Cool completely before frosting; warm cake makes buttercream slide right off. If you are in a hurry, chill the cake for 30 minutes.
- If you want a simpler spread, try a light dusting of powdered sugar and skip the buttercream; it is lovely and less sweet. For more simple recipes that prioritize few ingredients, take a look at this 3-ingredient pancake idea for breakfast inspiration.
Fun Ways to Switch It Up
- Swap half the cocoa for melted dark chocolate for a richer swirl.
- Add orange zest to the vanilla batter and top with an orange glaze for a citrus-chocolate lift.
- Fold in 1/2 cup mini chocolate chips for pockets of melty goodness.
- Make it into cupcakes: portion into lined tins and reduce bake time to 18-22 minutes.
- For a lighter take, replace half the butter with Greek yogurt and reduce sugar slightly. If you enjoy minimal-ingredient creations, check this four ingredient pancake inspiration for simple flavor swaps.
How to Serve and Savor
Slice this cake with a sharp, serrated knife to keep the swirls intact. Serve with a dollop of whipped cream and a handful of fresh berries for contrast. For coffee breaks, the cake’s soft, buttery crumb sings alongside a bright espresso or a lightly roasted tea. If you want to make a show of it, pipe the buttercream in generous rosettes and scatter toasted almonds for crunch and sparkle.
Keeping Your Cake Fresh
Room temperature: Store covered at room temperature for up to 2 days to retain the soft crumb. Refrigeration: For longer storage, wrap tightly and refrigerate up to 5 days; allow to come to room temperature before serving for the best texture. Freezing: Freeze slices or the unfrosted whole cake wrapped tightly in plastic and foil for up to 3 months. Thaw in the refrigerator overnight, then bring to room temperature before frosting. Reheating: A 10-second zap in the microwave on low can revive a slice, but avoid overheating.
Questions You Might Have
Q: Can I make this dairy-free?
A: Yes. Substitute dairy milk with an unsweetened plant milk and use a vegan butter substitute in both cake and buttercream. Expect slightly different texture but the marbling will shine.
Q: My cake sinks in the middle. Why?
A: Common reasons are underbaking, opening the oven too early, or too much leavening. Check doneness with a toothpick and avoid jostling the oven while it bakes.
Q: How do I get sharp marbling lines?
A: Use thicker dollops of each batter and a few firm swipes with a knife. Thin batters blend more, so keep both batters similar in viscosity.
Q: Can I use a bundt pan?
A: Yes. Reduce baking time slightly and check at 35-45 minutes depending on pan volume.
