How to Make Cake with Strawberry Filling

Making a cake with strawberry filling brings fresh, juicy flavors to any occasion. This recipe creates a moist vanilla cake layered with homemade strawberry filling. It’s perfect for birthdays, parties, or simple desserts. You can bake it at home with basic ingredients.

This guide walks you through every step. You’ll learn to prepare the cake batter, cook the filling, and assemble everything. Expect a tender crumb and bursts of strawberry sweetness. Let’s get started.

Ingredients You’ll Need

Gather these items for the cake layers. They serve 12 people.

For the cake:

• 2 ½ cups all-purpose flour
• 2 ½ teaspoons baking powder
• ½ teaspoon salt
• 1 cup unsalted butter, softened
• 2 cups granulated sugar
• 4 large eggs, room temperature
• 1 tablespoon vanilla extract
• 1 ¼ cups whole milk, room temperature

For the strawberry filling:

• 4 cups fresh strawberries, hulled and chopped
• ¾ cup granulated sugar
• ¼ cup cornstarch
• 2 tablespoons lemon juice
• 1 teaspoon vanilla extract

For the frosting:

• 1 cup unsalted butter, softened
• 4 cups powdered sugar
• ¼ cup heavy cream
• 1 teaspoon vanilla extract
• Pinch of salt

These amounts yield two 9-inch cake layers. Use fresh strawberries for the best taste. Frozen ones work in a pinch, but thaw them first.

Preparing the Strawberry Filling

Start with the filling. It needs time to cool and thicken.

1. Wash and hull the strawberries. Chop them into small pieces. This helps them break down evenly.
2. In a medium saucepan, combine the chopped strawberries, sugar, cornstarch, and lemon juice. Stir well. The cornstarch thickens the mixture as it cooks.
3. Place the pan over medium heat. Bring it to a gentle boil. Stir constantly for 5-7 minutes. The filling will turn glossy and thick. It should coat the back of a spoon.
4. Remove from heat. Stir in the vanilla extract. Let it cool completely. This takes about 1 hour at room temperature. For faster cooling, place it in the fridge for 30 minutes. Cover it with plastic wrap to prevent a skin from forming.

Your filling is ready. It holds its shape well between cake layers.

Baking the Cake Layers

1. Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans. Line the bottoms with parchment paper. This ensures easy release.
2. In a medium bowl, whisk together the flour, baking powder, and salt. Set it aside.
3. Use a stand mixer or hand mixer. Beat the softened butter and sugar on medium speed for 3 minutes. The mixture should turn light and fluffy.
4. Add the eggs one at a time. Beat well after each addition. Scrape down the bowl sides as needed. Mix in the vanilla extract.
5. With the mixer on low, add the dry ingredients in three parts. Alternate with the milk. Start and end with the flour mixture. Mix just until combined. Overmixing makes the cake tough.
6. Divide the batter evenly between the pans. Smooth the tops with a spatula.
7. Bake for 25-30 minutes. A toothpick inserted in the center should come out clean. Cool in the pans for 10 minutes. Then transfer to wire racks. Cool completely, about 1 hour.

Making the Buttercream Frosting

While the cakes cool, prepare the frosting. It provides a smooth finish.

1. Beat the softened butter on medium speed until creamy, about 2 minutes.
2. Add the powdered sugar one cup at a time. Mix on low to avoid a sugar cloud. Scrape the bowl often.
3. Pour in the heavy cream, vanilla, and salt. Beat on high for 3 minutes. The frosting becomes light and spreadable.

Taste it. Add more sugar if you want it sweeter. Set aside until assembly.

Assembling the Cake with Strawberry Filling

Assembly is key for a stunning cake. Work on a cake board or plate.

1. Level the cake tops if domed. Use a serrated knife for even slices.
2. Place one layer on your serving plate. Spread 1 ½ cups of strawberry filling evenly over it. Leave a ½-inch border. This prevents spillover.
3. Top with the second cake layer. Press gently.
4. Apply a thin crumb coat of frosting. Spread it over the top and sides. Chill for 15 minutes. This traps crumbs.
5. Frost the cake generously. Use an offset spatula for smooth sides. Pipe rosettes on top if desired.
6. Spoon extra strawberry filling into a piping bag. Pipe dollops around the edge. Garnish with whole strawberries.

Chill the cake for 30 minutes before serving. It slices cleanly.

Tips for Perfect Results

• Use room-temperature ingredients. They blend smoothly for even batter.
• Do not overbake. Check at 25 minutes.
• Make filling ahead. It stores in the fridge up to 3 days.
• For stability, chill assembled cake before transport.
• Scale up for crowds. Double the recipe for a 3-layer cake.
• Avoid watery filling. Cook it until thick.
• Fresh strawberries shine in summer. Use ripe ones for peak flavor.

Variations to Try

• Add whipped cream between layers for lightness.
• Swap vanilla cake for chocolate. The strawberry contrast pops.
• Make cupcakes. Fill cores with strawberry mixture.
• Go vegan. Use plant-based butter, milk, and egg replacers.
• Infuse filling with basil or mint for a twist.
• Top with chocolate ganache for decadence.

These changes keep it exciting.

Storing and Serving

• Store leftovers in an airtight container. Refrigerate up to 4 days. The filling keeps it moist.
• Freeze slices wrapped in plastic and foil. Thaw overnight in the fridge.
• Serve at room temperature. Flavors bloom best.
• Pair with coffee or sparkling wine.

Frequently Asked Questions (FAQs)

1. Can I use frozen strawberries for the filling?

Yes. Thaw and drain them first. Reduce sugar slightly as they release more juice.

2. How do I fix runny strawberry filling?

Cook longer or add more cornstarch slurry. A slurry is equal parts cornstarch and water.

3. What’s the best flour for this cake?

All-purpose works best. Cake flour makes it softer but less sturdy for filling.

4. Can I make this cake gluten-free?

Yes. Swap for a 1:1 gluten-free flour blend. Add xanthan gum if not included.

5. How far ahead can I assemble the cake?

Assemble a day early. Store covered in the fridge. Let it sit out 1 hour before serving.
