Ingredients You’ll Need

The image shows a top view of 10 baking ingredients neatly arranged on a white marbled surface. There are two large clear glass bowls at the top, one with white flour on the left and one with white sugar on the right. Below them, a medium clear bowl holds a white liquid, likely milk or cream. To the right of this bowl are three brown eggs, arranged closely. Surrounding the larger bowls are smaller clear glass bowls, each holding different ingredients: a golden yellow liquid (oil) on the left bottom, a light beige liquid below the oil, white salt, white baking powder, dark brown vanilla extract, and two other small bowls with white powders, all evenly spaced. The overall look is clean and organized. photo taken with an iphone --ar 4:5 --v 7

Don’t let the list fool you—these ingredients are simple pantry staples, but they each play a vital role in building this cake’s irresistible flavor and texture. From tender cake crumbs to smooth cream filling, every component complements one another beautifully.

Cake flour: 2 ¼ cups – This gives the sponge that soft, delicate crumb you want in a perfect vanilla cake.
Granulated sugar (for cake): 1 ½ cups – Sweetens the cake just right without overpowering the vanilla.
Baking powder: 2 teaspoons – Helps the cake rise to fluffy perfection.
Baking soda: ½ teaspoon – Adds lift and enhances browning.
Salt: ½ teaspoon – Balances the sweetness and intensifies flavor.
Buttermilk: 1 cup – Keeps the sponge moist while adding a subtle tang.
Milk: ¼ cup – Lightens the batter for tender crumb texture.
Vanilla extract: 1 tablespoon – Infuses the cake with warm, classic vanilla aroma.
Vegetable oil: ½ cup – Ensures the sponge stays moist and soft for days.
Eggs: 3 large, room temperature – Provide structure and richness to the cake.
Granulated sugar (for cream): 1 ½ cups – Sweetens the creamy filling for that signature Twinkie taste.
Flour (for cream): ½ cup – Thickens the filling into a smooth, pudding-like texture.
Milk (for cream): 2 cups – Creates the luscious base for the custard filling.
Unsalted butter: 2 cups, room temperature – Whipped into fluffy perfection, it creates the silky cream layer.
Vanilla extract (for cream): 2 tablespoons – Brightens the flavor and ties the cake and filling together.
Salt (for cream): 1-2 dashes – Just enough to enhance sweetness and balance flavors.

How to Make Twinkie Cake with Vanilla Sponge and Cream Filling Recipe

Step 1: Preparing the Vanilla Sponge Cake

Start by preheating your oven to 350 degrees Fahrenheit and greasing a 9×13 inch baking pan with a quick spray. The baking pan choice ensures an even bake and a beautiful rectangular shape reminiscent of classic Twinkies. Combine your dry ingredients—cake flour, sugar, baking powder, baking soda, and salt—in a medium bowl and whisk them together until evenly mixed for an airy crumb.

Step 2: Mixing Wet Ingredients

In a separate large bowl, whisk the buttermilk, milk, vanilla extract, vegetable oil, and eggs until well combined. The combination of buttermilk and oil is what keeps this sponge incredibly tender and moist, far surpassing any box mix you might have tried before. Slowly add the dry ingredients to the wet and stir gently but thoroughly until just combined—avoid overmixing for the fluffiest cake!

Step 3: Baking and Cooling

Pour the batter evenly into your prepared pan and bake for 35 to 40 minutes. You’ll know it’s ready when a toothpick inserted in the center comes out clean. Let the cake cool thoroughly before removing it from the pan—patience here pays off, as it helps the cake hold its shape when layering. Once cooled, carefully slice the cake horizontally into two even layers to prepare for that dreamy cream filling.

Step 4: Making the Cream Filling (Ermine Frosting)

Combine the flour, sugar, and milk in a saucepan over medium heat. Whisk continuously to prevent lumps, cooking until the mixture thickens like pudding—this usually takes about 10 minutes. Remove it from heat and transfer to a shallow dish, covering with plastic wrap pressed directly on the surface to avoid a skin forming. Chill in the refrigerator for at least 40 minutes. Meanwhile, whip your room temperature butter in a stand mixer using a whisk attachment for about 8 minutes until it’s light and fluffy.

Step 5: Assembling the Cream Filling

With your butter whipped to perfection and the pudding mixture chilled, gradually add spoonfuls of the pudding to the butter, mixing continuously. Swap to the paddle attachment and add vanilla extract plus a pinch of salt, then beat on medium-high speed for 10 to 13 minutes until the frosting is luxuriously smooth and fluffy—the hallmark of a perfect cream filling that elevates this cake from good to unforgettable.

Step 6: Assembling the Cake

Spread a generous, even layer of the cream filling between the two vanilla sponge layers. For that classic Twinkie cake look and clean taste, smooth the sides and top edges carefully. Chill the cake for at least an hour to let the flavors meld and the frosting firm up before serving. This extra step ensures every slice stays intact, showcasing the beautiful layers you’ve created.

The image shows a light golden square cake cut into nine even pieces, with two pieces slightly pulled out to show the inside. The cake has two layers separated by a thick, smooth white cream filling. The texture of the cake is soft and slightly porous, and the surface is evenly baked with a light brown top. The cake rests on white parchment paper on a surface with a white marbled texture, and a blue fringed cloth is partially visible on the left side. One piece is held by a metal spatula at the bottom right corner, slightly lifting it from the rest. Photo taken with an iphone --ar 4:5 --v 7

Garnishes

A light dusting of powdered sugar or a few fresh berries can add a subtle touch of elegance without distracting from the cake’s nostalgic charm. A sprinkle of toasted coconut or flaky sea salt on top can bring unexpected texture and flavor contrasts that guests will love discovering.

Side Dishes

Pair this cake with a simple side of fresh fruit or a small scoop of vanilla bean ice cream to keep the focus on the cake’s creamy, tender layers. For an adult twist, a drizzle of berry coulis or a cup of rich coffee complements the sweetness perfectly.

Creative Ways to Present

Try serving the Twinkie Cake with Vanilla Sponge and Cream Filling Recipe as individual mini portions by cutting into bite-sized squares. You can also pipe the cream filling between layers before assembling for a polished look or top with edible flowers for a stunning presentation at parties.

Make Ahead and Storage

Storing Leftovers

Store leftover cake covered tightly with plastic wrap or in an airtight container in the refrigerator to keep the cream filling fresh. It will stay moist and flavorful for up to 4 days—perfect if you want to savor it slowly or share with friends.

Freezing

This cake freezes wonderfully for longer storage. Wrap each slice individually in plastic wrap and place in a freezer bag or airtight container. When frozen properly, it will maintain quality for up to 2 months. Thaw overnight in the fridge before enjoying.

Reheating

Because of the cream filling, reheating is best avoided as it may affect texture. Instead, remove slices from the fridge and let them come to room temperature for about 20 minutes to bring out optimal flavor and softness.

FAQs

What makes this Twinkie Cake different from a regular vanilla cake?

This cake uniquely combines a delicate vanilla sponge with an ermine-style cream filling, which is less sweet and incredibly smooth compared to traditional buttercream, mimicking the classic Twinkie snack in cake form.

Can I make the cream filling ahead of time?

Absolutely! The cream filling can be made a day in advance and stored in the refrigerator. Just be sure to bring it to room temperature and re-whip briefly before assembling the cake.

Is there a substitution for buttermilk in the sponge?

If you don’t have buttermilk on hand, you can make a substitute by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of milk and letting it sit for 5 minutes. This helps replicate the acidity and tenderness buttermilk provides.

How do I get even cake layers when slicing?

Use a serrated knife and cut slowly using a sawing motion. For extra precision, chill the cake for a bit beforehand, so it firms up to reduce crumbling while slicing.

Can I use another frosting instead of the ermine filling?

You can, but part of what makes this Twinkie Cake with Vanilla Sponge and Cream Filling Recipe so special is the unique lightness and flavor of the ermine frosting. Substitute with whipped cream or a light buttercream if needed, but the original filling is highly recommended.
