Strawberry Seismic Cake

How to Make Strawberry Seismic Cake

Making this cake involves preparing a light and fluffy sponge, a thick strawberry filling, and a smooth buttercream frosting. Follow these steps to assemble the perfect layered cake.

Step 1: Prepare the Strawberry Filling

  1. In a saucepan over medium heat, combine the chopped strawberries, sugar, cornstarch, and lemon juice.
  2. Stir frequently, cooking until the strawberries break down and the mixture thickens (about 10-15 minutes).
  3. Remove from heat and allow to cool completely before using.

Step 2: Bake the Vanilla Sponge

  1. Preheat your oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  3. In a large mixing bowl, beat butter and sugar until light and fluffy (about 3 minutes).
  4. Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
  5. Alternate adding the flour mixture and milk, beginning and ending with the flour. Mix until just combined.
  6. Divide the batter evenly among the prepared cake pans.
  7. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
  8. Let cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Step 3: Make the Buttercream Frosting

  1. Beat the softened butter until creamy and smooth.
  2. Gradually add powdered sugar, mixing on low speed to avoid a sugar cloud.
  3. Pour in heavy cream and vanilla extract, then beat until fluffy.
  4. Mix in ¼ cup of the cooled strawberry filling to give the buttercream a hint of strawberry flavor.

Step 4: Assemble the Cake

  1. Place one cake layer on a serving plate. Spread a generous amount of strawberry filling over the top.
  2. Add the second cake layer and repeat the process.
  3. Place the final cake layer on top and spread a thin crumb coat of buttercream over the entire cake. Chill for 15 minutes.
  4. Apply the remaining buttercream, smoothing it with an offset spatula.
  5. Pipe decorative swirls around the edges and drizzle extra strawberry sauce if desired.
  6. Garnish with fresh strawberries for a beautiful finish.

This cake is now ready to serve, offering layers of soft sponge, rich strawberry filling, and creamy frosting in every bite.

How Long to Bake Strawberry Seismic Cake

The baking time for the vanilla sponge depends on the size of the cake layers and your oven’s accuracy. Follow these general guidelines to achieve perfectly baked cakes:

  • Three 8-inch cake layers – Bake for 25-30 minutes at 350°F (175°C).
  • Two 9-inch cake layers – Bake for 30-35 minutes.
  • Cupcakes – Bake for 18-20 minutes if using the batter for cupcakes.

To check for doneness, insert a toothpick into the center of the cake. If it comes out clean or with a few crumbs, the cake is ready. Avoid overbaking, as it may dry out the sponge.

How to Store Leftovers

If you have any leftovers, store them properly to keep the cake moist and fresh for as long as possible.

  • Refrigerator – Store the cake in an airtight container in the fridge for up to 4 days. Let it sit at room temperature for 15-20 minutes before serving for the best texture.
  • Freezer – Wrap individual cake slices tightly in plastic wrap and place them in a freezer-safe container. Freeze for up to 2 months. Thaw overnight in the refrigerator before enjoying.
  • Make-Ahead Option – You can bake the cake layers in advance and freeze them. Wrap each layer tightly and store for up to 1 month before assembling with frosting and filling.

Tips for the Perfect Strawberry Seismic Cake

To ensure your cake is light, moist, and full of flavor, follow these expert tips:

  • Use Room Temperature Ingredients – Butter, eggs, and milk should be at room temperature for a smooth batter.
  • Chill the Cake Before Frosting – A quick chill in the refrigerator helps prevent the cake layers from shifting while frosting.
  • Level the Cake Layers – Trim the tops of each cake layer for an even, professional-looking stack.
  • Don’t Overmix the Batter – Overmixing can lead to a dense cake. Mix until ingredients are just combined.
  • Enhance the Strawberry Flavor – Add a touch of strawberry extract to the cake batter for an extra burst of berry flavor.

With these tips, your Strawberry Seismic Cake will be a stunning, delicious centerpiece at any gathering. Enjoy every bite of this rich, fruity masterpiece!
