Ingredients for 8in cake
These 12 ingredients create a restaurant-quality vanilla bean cake with stunning swirls—all in one pan!
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed, room temp |
| Large Eggs 🥚 | 3 whole | Room temperature preferred |
| Vanilla Bean Paste 🌿 | 2 tbsp | High-quality for authentic flavor |
| Baking Powder 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Milk 🥛 | ½ cup | Whole or 2% preferred |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla extract |
| Powdered Sugar 🍚 | 1 cup | For buttercream (optional) |
| Heavy Whipping Cream 🥛 | ½ cup | Cold for buttercream (optional) |
| Vanilla Bean Seeds 🌿 | 1 whole | Scraped for swirls (optional) |
The vanilla bean paste is the secret weapon here—look for high-quality brands like Nielsen-Massey at specialty stores or online. The paste gives that authentic vanilla flavor without the hassle of scraping seeds. For the butter, use cold, cubed pieces that just start to soften when you touch them. This ensures tender layers instead of dense cake. If you’re feeling fancy, grab a whole vanilla bean from Whole Foods or a gourmet shop to scrape seeds for the swirls—it’s worth the extra touch. The flour? King Arthur or Gold Medal brands work best for that tender crumb.
No vanilla bean paste? Use 1 tbsp pure vanilla extract plus 1 tsp sugar to mimic the depth. Running short on powdered sugar for buttercream? Process granulated sugar in a food processor until fine. The milk can be swapped for almond or oat milk if needed, but whole dairy gives the best texture. For the swirls, if you can’t find a whole vanilla bean, use extra vanilla extract plus a pinch of cinnamon for warmth. The baking powder is critical—don’t substitute baking soda, or your cake will taste metallic. Want to make it gluten-free? Swap the flour for a 1:1 gluten-free blend like Bob’s Red Mill.
This cake keeps beautifully—3 days at room temperature covered loosely, or 1 week refrigerated in an airtight container. For longer storage, freeze the whole cake (unfrosted) for up to 3 months. Thaw overnight at room temperature. Pro tip: Wrap tightly in plastic wrap before refrigerating to keep it moist. The buttercream, if made, stays fresh for 5 days refrigerated—just whip it back up before serving. I always make a double batch of batter and freeze half for next time—saves so much stress when you’re short on time.

Step-by-step instructions for vanilla bean swirl cake
Here’s how to create a showstopping vanilla bean cake with rich swirls and tender layers—all in one pan!
Prepare the Cake Batter
Preheat your oven to 350°F and grease an 8-inch round cake pan with butter, then line the bottom with parchment paper. In a medium bowl, whisk together the 2 cups all-purpose flour, 1.5 cups granulated sugar, 1.5 tsp baking powder, and 0.5 tsp salt. Sift the dry ingredients once more to ensure a light, airy texture—this prevents dense cake layers later.
In a separate large bowl, beat the 1 cup unsalted butter until smooth and creamy, about 3-4 minutes. Add the 3 whole large eggs, one at a time, beating well after each addition. Mix in the 2 tbsp vanilla bean paste and 1 tsp vanilla extract until fully combined. Gradually add the dry ingredients to the wet, mixing on low speed just until incorporated—overmixing develops gluten, which can make the cake tough.
Finally, pour in the 0.5 cup milk and stir until the batter is smooth and glossy. The batter should be thick but pourable. Here’s the thing—don’t worry if it looks slightly under-mixed. The swirls will create their own texture as we fold them in later.
Create the Vanilla Bean Swirls
Scrape the seeds from the 1 whole vanilla bean and set aside. In a small bowl, combine the 1 cup powdered sugar with the 0.5 cup cold heavy whipping cream and the vanilla bean seeds. Whip with a hand mixer until soft peaks form—this will be our swirl filling. The cream should hold its shape when the whisk is lifted, but don’t overbeat or it’ll turn grainy.
Pour half of the cake batter into the prepared pan and spread it evenly. Drop spoonfuls of the vanilla cream mixture over the batter, then use a knife to gently swirl it through the batter in a circular motion. This creates those beautiful marbled patterns. Pour the remaining batter over the swirls and smooth the top with a spatula.
Here’s where it gets fun—run a knife around the edges of the pan to release any air bubbles. Tap the pan gently on the counter a few times to settle the batter. The cake should rise beautifully in the center with those stunning swirls peeking through.
Bake to Golden Perfection
Bake the cake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The cake is done when the edges are golden brown and the top springs back when gently pressed. I know it’s tempting to open the oven early, but resist! The cake needs that full baking time to set properly.
Once baked, let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. This gradual cooling prevents cracking. While it cools, you can make a simple glaze if you like—just mix 0.5 cup powdered sugar with 1-2 tbsp milk and drizzle it over the cooled cake for extra shine.
Slice the cake into 8 equal wedges and serve. Each bite should deliver that perfect balance of tender cake, creamy vanilla swirls, and buttery richness. The secret to this cake’s success lies in the swirl technique—don’t rush the folding, and always use room-temperature ingredients for even baking.
Pro Tips For Making 8in Cake
- Cream Butter Properly: Beat the butter and sugar until it’s pale, fluffy, and holds a ribbon when the beater lifts—about 3-5 minutes. I used to cut corners here, but this step actually lightens the texture and makes the cake tender. Skip it, and you’ll end up with a dense brick.
- Sift That Flour: Sift the flour (and baking powder, if in your recipe) directly over the butter-sugar mix to avoid lumps. I learned this the hard way—mixing dry ingredients into wet ones with a spoon just creates a mess. A fine sift also means a smoother crumb.
- Don’t Overmix the Batter: Stop folding in the flour as soon as it’s just combined—no streaks, but no overworking either. Overmixing develops gluten and turns your cake into a chewy disaster. The moment it looks like cookie dough, call it done.
- Rotate the Pan: Swap the cake pan’s position in the oven halfway through baking (front to back, top to bottom). My first cake had a dark top and pale sides—turning the pan evens the heat and guarantees a golden crust all around. No excuses for uneven baking.
Dietary considerations for this recipe
Gluten-Free Adaptation
For a gluten-free version, replace the 2 cups all-purpose flour with 2 cups Bob’s Red Mill 1:1 Gluten-Free Baking Flour. This blend mimics the texture of wheat flour perfectly, ensuring your cake stays tender and moist.
I’ve tested this substitution with great results—just make sure to sift the flour well to avoid lumps. The gluten-free batter will be slightly thicker, so you may need to add 1-2 tablespoons of milk to reach the right consistency. 🌾
Dairy-Free Options
This cake can easily accommodate dairy-free needs by swapping the 1 cup unsalted butter for 1 cup dairy-free butter (like Miyoko’s or Earth Balance) and using ½ cup unsweetened almond milk instead of regular milk.
For the vanilla cream swirls, replace the ½ cup heavy whipping cream with ½ cup coconut cream (chilled overnight). The texture remains rich and creamy, though slightly lighter. Always use full-fat dairy alternatives for the best results. 🥛
Nut-Free Considerations
If nut allergies are a concern, avoid the vanilla bean paste brands that contain almonds (like some Nielsen-Massey varieties) and opt for a pure vanilla extract instead. For the dairy-free swirls, use oat milk whipped cream (like Oatly Barista) instead of coconut cream if nut-free is a priority.
Double-check all ingredient labels, especially for hidden nut traces in baking powder or powdered sugar. Safety first! 🌿
Lower Sugar Version
To reduce sugar content, decrease the 1.5 cups granulated sugar to 1 cup and replace the 1 cup powdered sugar in the swirls with ½ cup powdered sugar + ½ cup coconut sugar. The cake will still taste sweet but with a more natural depth.
For extra richness, add 1 teaspoon of maple syrup to the batter. This adjustment works beautifully without compromising the cake’s moisture or texture. 🍚
Egg-Free Substitution
Replace the 3 large eggs with 3 tablespoons of ground flaxseed mixed with 9 tablespoons of water (let it sit for 5 minutes to thicken). This flax “egg” works as a binder and adds moisture.
For the vanilla cream swirls, use ½ cup aquafaba (chilled chickpea brine) whipped to stiff peaks—it mimics the texture of whipped cream perfectly. The cake may be slightly denser but still delicious. 🥚

Frequently asked questions
Can I use this recipe for a different-sized cake pan?
This recipe is specifically designed for an 8-inch round pan to achieve the perfect swirl pattern and baking time. For a 9-inch pan, increase baking time by 5-7 minutes and reduce oven temperature to 340°F to prevent over-browning. For smaller pans (6-inch), reduce batter by 50% and bake at 350°F for 20-25 minutes. Always adjust baking time based on your specific pan and oven.
Why does my cake have a dense texture?
Dense cake usually happens from overmixing the batter or using cold ingredients. Make sure to mix the wet and dry ingredients just until combined—30-40 strokes max. Also, ensure your butter, eggs, and milk are at room temperature (around 68°F). Overmixing develops gluten, which makes the cake tough. If your oven runs hot, reduce temperature by 10°F or check for doneness 5 minutes early.
How do I make the swirls look more professional?
For perfect swirls, use a long, thin spatula or knife to create clean lines. Pour half the batter, then drop spoonfuls of the vanilla cream mixture evenly. Use the spatula to make 3-4 even swirls in a circular motion before adding the remaining batter. Tap the pan gently on the counter to release air bubbles, and avoid over-swirling—3-4 rotations max per section. Patience is key!
Can I bake this cake in a glass pan?
Yes, but you’ll need to adjust the baking time and temperature. Glass pans absorb heat differently, so reduce oven temperature to 340°F and bake for 25-30 minutes. Glass pans also require 10-15 minutes less cooling time before removing from the pan. Always use a thermometer to check doneness—205°F at the center indicates it’s fully baked.
What’s the best way to store leftover cake?
For short-term storage (3 days), keep the cake at room temperature in an airtight container with a paper towel underneath to absorb moisture. For longer storage (1 week), refrigerate in an airtight container. To freeze, wrap the whole cake tightly in plastic wrap and aluminum foil, then store for up to 3 months. Thaw overnight at room temperature before serving.
