This Trader Joe's-inspired vanilla bean sheet cake delivers ultra-moist layers with a signature bourbon swirl that feels like a bakery secret.

I've perfected this recipe to ensure every slice stays tender and flavorful, with a golden crust that's impossible to resist.

What sets this sheet cake apart is the combination of Trader Joe's vanilla extract and a touch of bourbon, which adds depth without overpowering the delicate vanilla flavor.

The cake batter is designed to be simple yet foolproof, with a focus on achieving that signature moist texture that keeps it fresh for days. The bourbon swirl adds a subtle caramel note that elevates the classic vanilla experience.

By the time you pull this cake from the oven, you'll have a golden, fragrant masterpiece with layers that are impossibly tender and a swirl of bourbon-infused filling that ties everything together.

Serve warm with a dusting of powdered sugar and fresh berries, or drizzle with a vanilla glaze for an extra touch of elegance. The cake's versatility makes it perfect for birthdays, holidays, or simply treating yourself to something extraordinary. Here's how to create this showstopper in your own kitchen.

Ingredients for trader joe's vanilla bean sheet cake

Twelve simple ingredients transform into a showstopping sheet cake with layers so moist they'll have everyone asking for seconds.

The vanilla bean paste is non-negotiable here—Trader Joe's makes the best, and it's worth hunting down if your store doesn't carry it. The bourbon adds depth, so grab a decent bottle (I like Maker's Mark or Buffalo Trace), but don't break the bank—any good bourbon will do. For the butter, full-fat is a must—none of that low-fat nonsense. Room temperature butter mixes better, so take it out 30 minutes before you start. The flour? Sift it—trust me, it makes all the difference in that cloud-like texture.

No bourbon? Dark rum or even more vanilla extract (2 tsp extra) works in a pinch. Fresh out of vanilla bean paste? Double the extract, but it won't be the same—this recipe was built for that rich, swirled flavor. The blueberries are optional but add a pop of color. If you're feeling fancy, make the vanilla glaze (powdered sugar + milk + vanilla extract) or just dust with powdered sugar. For the milk, whole milk gives the best texture, but 2% works too if that's what you've got. The baking powder needs to be fresh—if it's over a year old, toss it.

This cake keeps beautifully—3 days at room temperature covered loosely, or 5 days in the fridge wrapped tight. The bourbon flavor actually improves with a day or two of resting, so make it ahead if you can. For serving, slice with a serrated knife and dust each piece with powdered sugar. Leftovers? Toasted slices are my favorite—just pop them in the toaster for 30 seconds until golden. The glaze sets up nicely, so drizzle it right before serving for that bakery touch.

Step-by-step instructions for Trader Joe's vanilla bean sheet cake recipe

Here's how to create layers so moist they'll make you forget store-bought cakes exist.

Preheat your oven to 350°F and grease a 9x13-inch baking pan with butter, then dust with flour. In a large mixing bowl, cream together the 1 cup unsalted butter and 2 cups granulated sugar on medium speed until light and fluffy—about 3-4 minutes. This step is crucial for airy layers that stay tender.

Add the 3 whole large eggs, one at a time, mixing well after each addition. Stir in the 0.5 cup Trader Joe's vanilla bean paste and 0.5 cup bourbon. The bourbon adds depth and helps keep the cake moist—don't skip it! In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 teaspoons baking powder, and 0.5 teaspoon salt. Gradually add the dry ingredients to the wet mixture, alternating with the 1 cup milk, beginning and ending with flour.

Pour the batter into the prepared baking pan and spread it evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden on top but still slightly springy to the touch. Overbaking dries out the layers, so keep an eye on it—especially if your oven runs hot.

Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. This resting period ensures even slicing and prevents crumbling when you add the swirl later. Patience here makes all the difference for that signature moist texture.

Once the cake is fully cooled, use a serrated knife to cut it horizontally into three equal layers. Place the middle layer on a plate and spread ½ cup of the vanilla glaze evenly over it. This layer will become the heart of your swirl. Stack the remaining two layers on top, pressing gently to keep them in place.

Next, take a sharp knife and make vertical cuts about 1 inch apart through all three layers, but not all the way to the bottom. This creates channels for the bourbon to seep through. Pour the 0.5 cup bourbon evenly over the top of the cake, letting it drip down into the cuts. The alcohol will evaporate during baking, leaving behind rich flavor without overpowering the vanilla.

Spread the remaining ½ cup vanilla glaze evenly over the top and sides of the cake. Use a spatula to smooth it out, creating a glossy finish. Let the glaze set for 10 minutes before slicing. This final step adds sweetness and a professional touch, but it's also what keeps the cake moist for days.

Garnish with 1.5 cups fresh blueberries if desired, arranging them neatly on top for a pop of color. Serve at room temperature for the best texture—each slice should be tender, flavorful, and perfectly moist, just like a bakery classic. Store leftovers covered at room temperature for up to 3 days or refrigerate for up to 5 days (bring to room temperature before serving).

Creative variations of this dish

Bourbon Vanilla Twist

The bourbon swirl isn't just a gimmick—it transforms this vanilla cake into something extraordinary. I like using Maker's Mark or Buffalo Trace bourbon because their caramel notes complement the vanilla beautifully.

For a milder version, reduce the bourbon to ¼ cup and add 1 tsp extra vanilla extract to maintain moisture. The alcohol evaporates during baking, leaving behind a subtle, sophisticated depth that pairs perfectly with the rich vanilla flavor. 🍷

Espresso Infusion

Add 1 tbsp instant espresso powder to the dry ingredients for a mocha twist that cuts through the sweetness. The espresso enhances the vanilla while adding a subtle bitterness that balances the richness.

I recommend Starbucks Via or Nescafé Azera for consistent results. This variation works especially well when paired with a dark chocolate ganache drizzle on top.

Citrus Zest Layers

Zest 1 lemon and 1 orange (about 1 tbsp each) and fold it into the batter for a bright, citrusy contrast. The acidity keeps the cake from tasting too heavy, and the oils in the zest add a lovely aroma.

For extra flair, add 1 tbsp citrus juice to the glaze. This version shines when served with a dollop of whipped cream and a sprinkle of toasted coconut flakes.

Spiced Chai Variation

Warm ½ cup milk with 1 chai tea bag (steeped for 5 minutes) and let it cool before using it in place of regular milk.

Add ½ tsp ground cinnamon, ¼ tsp ground cardamom, and ¼ tsp ground ginger to the dry ingredients for a cozy, aromatic twist. This spiced version pairs beautifully with a caramel drizzle and candied pecans on top for crunch.

Salted Caramel Swirl

Replace half the bourbon with ½ cup caramel sauce (homemade or store-bought) for a decadent twist. After cutting the layers, spread ¼ cup caramel sauce on the middle layer before adding the bourbon. Finish with a sprinkle of flaky sea salt (like Maldon) on top for a sweet-salty balance.

This version feels indulgent enough for a special occasion but still keeps the cake's signature moisture. 💫

Gluten-Free Adaptation

Swap the all-purpose flour for a 1:1 gluten-free baking flour blend (like King Arthur Measure for Measure) and add ½ tsp xanthan gum to the dry ingredients. Reduce the milk to ¾ cup to prevent a gummy texture.

The cake will still be moist, but the crumb will be slightly denser. This version works well with a vanilla bean glaze and fresh raspberries for garnish.
