Strawberry Boston Cake Recipe
Ingredients
For the Sponge Cake:
- 1 ½ cups all-purpose flour (sifted)
- 1 ½ tsp baking powder
- ¼ tsp salt
- ½ cup unsalted butter (room temperature)
- ¾ cup granulated sugar
- 2 large eggs (room temperature)
- 1 tsp vanilla extract
- ½ cup whole milk
For the Strawberry Filling:
- 2 cups fresh strawberries (chopped)
- ⅓ cup granulated sugar
- 1 tbsp lemon juice
- 1 tbsp cornstarch
- 2 tbsp water
For the Cream Layer:
- 1 cup heavy whipping cream (cold)
- 2 tbsp powdered sugar
- 1 tsp vanilla extract
For Garnish (Optional):
- Whole strawberries
- Mint leaves
Instructions
1. Prepare the Sponge Cake
Step 1: Preheat the oven to 350°F. Grease and flour two 8-inch round cake pans or line them with parchment paper.
Step 2: In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
Step 3: In a large mixing bowl, beat butter and sugar on medium speed until light and fluffy, about 3 minutes. Add eggs one at a time, beating well after each addition. Mix in the vanilla extract.
Step 4: Gradually add the dry ingredients to the wet mixture, alternating with the milk. Begin and end with the dry ingredients. Mix until just combined.
Step 5: Divide the batter evenly between the prepared cake pans. Smooth the tops with a spatula and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean. Allow cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
2. Make the Strawberry Filling
Step 1: In a saucepan, combine strawberries, sugar, and lemon juice over medium heat. Cook until the strawberries release their juices and soften, about 5-7 minutes.
Step 2: In a small bowl, mix cornstarch and water until dissolved. Stir the mixture into the saucepan with the strawberries.
Step 3: Cook for another 2-3 minutes, stirring constantly, until the filling thickens. Remove from heat and let it cool completely.
3. Whip the Cream Layer
Step 1: In a large mixing bowl, whip heavy cream with an electric mixer on high speed until soft peaks form.
Step 2: Add powdered sugar and vanilla extract, then continue whipping until stiff peaks form. Be careful not to overmix.
4. Assemble the Strawberry Boston Cake
Step 1: Place one of the cooled sponge cakes on a serving plate. Spread an even layer of strawberry filling over the top.
Step 2: Gently place the second cake layer on top. Spread the whipped cream evenly over the top and sides of the cake for a smooth finish.
Step 3: Garnish with whole strawberries and mint leaves, if desired.

Directions
Follow these step-by-step instructions to create your Strawberry Boston Cake. Each step ensures a perfect balance of sweetness, freshness, and indulgence.
Prep
- Preheat the Oven: Set your oven to 350°F (175°C). Grease two 9-inch round cake pans with butter or cooking spray, and line them with parchment paper.
- Prep Ingredients: Measure out all the ingredients. Sift the all-purpose flour to ensure a light and airy cake texture. Wash, hull, and finely dice fresh strawberries for the filling.
- Organize Tools: Gather essential tools, like the mixing bowls, electric mixer, and whisk, making them easily accessible during the process.
Bake The Cake
- Mix the Wet Ingredients: In a large mixing bowl, beat together unsalted butter (½ cup softened), granulated sugar (1 cup), and 2 eggs until light and fluffy, about 2-3 minutes using an electric mixer on medium speed.
- Incorporate the Dry Ingredients: Combine 1 ½ cups all-purpose flour, 1 ½ tsp baking powder, and a pinch of salt in a separate bowl. Slowly add the dry ingredients into the wet mixture, alternating with ¾ cup whole milk and 1 tsp vanilla extract. Mix until just combined.
- Divide and Bake: Pour the batter evenly into the prepared pans. Smooth the tops with a rubber spatula. Bake in the preheated oven for 25-28 minutes, or until a toothpick inserted in the center comes out clean.
- Cool Completely: Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack. Let cool completely before assembly.
Prepare The Filling
- Cook the Strawberry Mixture: In a medium saucepan, combine:
- 2 cups fresh strawberries (diced, about 10-12 berries),
- 1 tbsp lemon juice,
- ¼ cup granulated sugar, and
- 1 tbsp cornstarch dissolved in 2 tbsp water.
Stir over medium heat until the mixture thickens, about 5-7 minutes. Remove from heat and let it cool to room temperature.
2. Consistency Tip: Ensure the strawberry mixture is thick and jam-like to prevent it from seeping out of the cake layers.
Make The Frosting
- Whip the Cream: In a chilled mixing bowl, pour 1 ½ cups heavy cream and add ½ cup powdered sugar. Whip using an electric mixer on high speed until medium peaks form—about 3-4 minutes.
- Optional Additions: Add 1 tsp vanilla extract or a dash of strawberry puree for additional flavor, if desired. Chill the frosting until ready to use.
Assemble The Cake
- Level the Cakes: Use a serrated knife to level the tops of the cake layers for even stacking.
- Add Strawberry Filling: Place the first cake layer on a cake turntable or serving plate. Spread the cooled strawberry mixture evenly over the top, leaving a small border around the edges.
- Layer and Frost: Place the second cake layer on top. Spread the whipped cream frosting generously over the top and sides of the cake using an offset spatula for a smooth finish.
- Decorate: Garnish with whole or halved fresh strawberries. Dust with powdered sugar or add a few mint leaves for an elegant touch.

Make-Ahead Instructions
When it comes to planning ahead, the Strawberry Boston Cake offers remarkable versatility. Preparing certain components ahead of time not only simplifies the process but also ensures that flavors deepen, resulting in an even more delightful dessert. Below, we’ll outline exactly what and how far in advance you can prepare each element of the cake.
Components You Can Make Ahead
1. Sponge Cake Layers
- Bake the sponge cake layers up to 2 days in advance.
- Once cooled completely, wrap each layer tightly in plastic wrap to prevent drying out.
- Store them at room temperature or in the freezer for up to 1 month if you need extra time. When freezing, wrap in an additional layer of aluminum foil for added protection.
2. Strawberry Filling
- Prepare the strawberry filling up to 1 week ahead.
- Store it in an airtight container in the refrigerator. This will allow the flavors to deepen while staying fresh.
- Pro Tip: If the filling thickens too much during storage, stir in a teaspoon of water or lemon juice before using to restore its spreadable consistency.
3. Whipped Cream Frosting
- The whipped cream frosting is best made fresh for optimal texture and stability. However, you can prepare it up to 1 day ahead and store it in the refrigerator in a sealed container.
- Before using, give it a quick whisk to restore its fluffy texture.
Assembly Scheduling
Below is a timing guide to help you organize your assembly:
| Task | Prep Time Ahead | Storage Tips |
|---|---|---|
| Sponge Cake Layers | 2 days / 1 month | Room temp (wrapped) or freezer (plastic + foil wrap) |
| Strawberry Filling | 1 week | Fridge (airtight container) |
| Whipped Cream Frosting | 1 day | Fridge (sealed container, whisk before use) |
Pro Tips for Make-Ahead Success
- If freezing the sponge cake layers, thaw them at room temperature for about 2-3 hours before assembling the cake.
- To reduce assembly day stress, we recommend completing the layers and filling in advance while leaving the frosting and full assembly for the day of serving.
- Use the freshest strawberries for garnishing right before serving to maintain their vibrant color and juiciness.
Tips For Success
Creating the perfect Strawberry Boston Cake takes careful attention to detail, and we are here to ensure you achieve bakery-quality results. With these essential tips, you’ll elevate your baking game and craft a show-stopping dessert every time.
1. Measure Accurately
For flawless results, use a kitchen scale to measure ingredients whenever possible. Baking is a science, and slight measurement errors can impact the texture of your sponge cake and the consistency of your filling. Stick to precise quantities as listed in the recipe.
2. Room Temperature Ingredients Are Key
Ensure your eggs, milk, and butter are at room temperature before you begin. Room temperature ingredients emulsify better, leading to a smoother batter and more tender cake layers.
3. Prepare Your Cake Pans Thoroughly
Grease and line your 9-inch round cake pans with parchment paper, ensuring even baking and easy removal. Overlooking this can lead to sticking, ruining the perfection of your cake layers.
4. Use Fresh, High-Quality Strawberries
Fresh strawberries are essential for the best flavor and vibrant color in your filling. Overripe strawberries may result in a mushy texture, so aim for firm, ripe berries when making your filling and garnishes.
Pro Tip: Taste your strawberries before using them. If they are not sweet enough, balance the filling by adding additional sugar – 1 to 2 teaspoons, depending on preference.
5. Do Not Overmix or Undermix the Batter
When combining wet and dry ingredients, mix gently until just incorporated. Overmixing develops too much gluten, resulting in a dense cake, while undermixing can leave flour pockets.
6. Cool Cakes Completely Before Assembly
Allow the cake layers to cool completely on a wire rack before assembly. Any warmth in the layers can melt the whipped cream frosting or make the strawberry filling too runny during layering.
7. Whip Cream to Stiff Peaks
To achieve a firm and fluffy whipped cream frosting, whip your heavy cream until stiff peaks form. This ensures the frosting holds its shape during assembly and presentation.
| Whipping Stages | Visual Cues |
|---|---|
| Soft Peaks | Peaks curl back onto themselves slightly. |
| Stiff Peaks | Peaks stand upright without collapsing. |
8. Level Cake Layers for Stability
Use a serrated knife to trim any domed tops from the baked cake layers. Flat layers ensure balanced stacking and prevent an uneven final result.
9. Chill the Cake Before Serving
Once assembled, chill the cake for at least 1 hour before slicing. This allows the flavors to meld, layers to set, and ensures a clean cut when serving.
10. Decorate Strategically
For a polished presentation, garnish the cake with whole strawberries, powdered sugar, and fresh mint leaves just before serving. This maintains their freshness and enhances the visual appeal.
By following these pro tips and tricks, we can guarantee your Strawberry Boston Cake will be the centerpiece of any occasion.
