What Ingredients You Will Need

This fluffy strawberry buttercream cake uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, with fresh strawberries bringing that seasonal, bright note.

• For the Moist Sponge Layers:
  • All-purpose flour – 2 ½ cups (320g), sifted (for the perfect tender crumb)
  • Baking powder – 2 ½ teaspoons (fresh is best for rise)
  • Salt – ½ teaspoon (balances sweetness)
  • Unsalted butter – 1 cup (227g), softened (I recommend Kerrygold for richness)
  • Granulated sugar – 1 ¾ cups (350g), for that sweet, tender bite
  • Large eggs – 4, room temperature (helps batter emulsify)
  • Whole milk – 1 cup (240ml), room temperature (use dairy-free milk like oat milk if needed)
  • Pure vanilla extract – 2 teaspoons (adds warm flavor)
• For the Strawberry Buttercream:
  • Unsalted butter – 1 cup (227g), softened (use high-quality for smoothness)
  • Powdered sugar – 4 cups (480g), sifted (for silky texture)
  • Fresh strawberries – 1 cup (150g), pureed and strained (adds natural sweetness and color)
  • Heavy cream – 2 tablespoons (30ml), optional for creaminess
  • Pure vanilla extract – 1 teaspoon (rounds out flavors)
  • Pinch of salt (balances sweetness)

If you want to switch things up, you can substitute almond flour for a gluten-free version, or swap the heavy cream in the buttercream with coconut cream for a dairy-free twist. Fresh strawberries are best here, but frozen can work in a pinch—just thaw and drain well to avoid watery frosting. I’ve always found that using small-curd cottage cheese or ricotta in some sponge recipes adds moisture, but for this cake, sticking to classic ingredients keeps it fluffy and light.

Equipment Needed

• Two 8-inch (20 cm) round cake pans – nonstick or well-greased
• Stand mixer or hand mixer – essential for whipping buttercream and creaming butter and sugar in the sponge
• Mixing bowls – at least two, medium and large sizes
• Sifter or fine mesh sieve – for flour and powdered sugar (helps avoid lumps)
• Rubber spatula – for folding batter gently and scraping bowls
• Cooling racks – to cool cakes evenly and avoid sogginess
• Offset spatula or butter knife – for frosting the cake smoothly
• Measuring cups and spoons – accurate measurements make all the difference

If you don’t have a stand mixer, a good hand mixer will do just fine—I’ve baked this cake plenty of times with both. For budget-friendly options, silicone spatulas and basic nonstick pans work wonders. Just make sure your pans are well-prepped to prevent sticking. I’ve learned the hard way that investing in a good quality sieve pays off when it comes to smooth batter and frosting.

Preparation Method

1. Preheat your oven to 350°F (175°C) and grease your two 8-inch cake pans. Line the bottoms with parchment paper for easy release. This step saves your cake from sticking and keeps the edges tender.
2. Whisk together dry ingredients: In a medium bowl, sift the flour, baking powder, and salt. Set aside. This ensures your sponge layers rise evenly and stay light.
3. Cream butter and sugar: Using a stand or hand mixer, beat the softened butter and granulated sugar on medium-high speed for about 4-5 minutes until pale and fluffy. This step is crucial for that airy cake texture.
4. Add eggs one at a time: Beat in eggs one by one, making sure each is fully incorporated before adding the next. Add vanilla extract with the last egg. This keeps the batter smooth and stable.
5. Alternate adding dry ingredients and milk: Reduce mixer speed to low. Add one-third of the flour mixture, then half the milk. Repeat, finishing with the flour. Mix each addition just until combined—overmixing can toughen the sponge.
6. Divide batter evenly: Pour the batter into the prepared pans, smoothing the tops with a spatula. Tap pans on the counter a couple of times to release any large air bubbles.
7. Bake for 25-30 minutes: The cakes are done when a toothpick inserted in the center comes out clean or with a few moist crumbs attached. Don’t overbake or the sponge will dry out.
8. Cool completely: Let cakes cool in pans for 10 minutes, then transfer to wire racks. Cooling fully is important before frosting to prevent melting your buttercream.
9. Prepare the strawberry buttercream: Beat softened butter on medium speed until creamy, about 2 minutes. Gradually add sifted powdered sugar, mixing on low until combined.
10. Add strawberry puree: Slowly beat in the fresh strawberry puree, vanilla extract, and salt. If the frosting is too stiff, add heavy cream, one tablespoon at a time, until spreadable but still holds shape.
11. Assemble the cake: Place one sponge layer on your serving plate. Spread a generous layer of strawberry buttercream on top. Add the second sponge and cover the entire cake with a thin crumb coat. Chill for 15 minutes, then apply a final smooth layer of frosting.
12. Optional decoration: Top with fresh strawberry slices or edible flowers for a pretty finish.

Pro tip: If your frosting feels too soft, pop it in the fridge for 10 minutes to firm up before spreading. Also, don’t rush folding the batter—gently is the keyword to keep that sponge ultra fluffy.

Cooking Tips & Techniques

One trick I swear by is using room temperature ingredients—it really helps the batter come together smoothly. Cold eggs or milk can make the batter look curdled, which is scary but fixable by mixing a little longer.

Avoid overmixing once you add the flour. You want to combine just until no streaks remain—overdoing it develops gluten and makes the cake tough, and nobody wants that. When creaming butter and sugar, patience is key; that fluffy, pale mixture traps air which gives you a light sponge.

For the strawberry buttercream, strain the puree to remove seeds; this keeps the frosting silky smooth. If your buttercream turns out too sweet, adding a pinch of salt balances it nicely. I learned that the hard way after a batch that was borderline saccharine!

Timing matters: bake your sponge layers right after mixing, and don’t leave the batter sitting around or it will lose air. While the cake cools, making the buttercream is a great multitasking win. And always cool the cakes completely before frosting—warm cakes melt the buttercream and you end up with a messy disaster.

Variations & Adaptations

• Dietary Swap: Use gluten-free flour blend instead of all-purpose flour for a gluten-free version. Make sure your baking powder is gluten-free too.
• Flavor Twist: Add a tablespoon of lemon zest to the sponge batter for a bright, citrusy note that pairs beautifully with strawberry.
• Dairy-Free Option: Swap butter for vegan margarine and use coconut cream instead of heavy cream in the buttercream. Use plant-based milk in the sponge.
• Seasonal Variation: Replace strawberry puree with raspberry or blueberry puree for a different fruity profile. In summer, fresh berries on top make a stunning garnish.
• Personal Favorite: Once, I folded in finely chopped toasted almonds between the layers for a delightful crunch, and it was a total hit at a family brunch.

Serving & Storage Suggestions

This cake is best served at room temperature to fully enjoy the fluffy sponge and creamy buttercream. Slice it with a sharp, serrated knife for clean edges. Pair it with a cup of freshly brewed tea or a glass of sparkling lemonade for a refreshing combo.

Store leftover cake covered in an airtight container in the refrigerator for up to 3 days. Bring slices to room temperature before serving to soften the buttercream and sponge. You can also freeze the cake (wrapped tightly in plastic wrap and foil) for up to 2 months—just thaw overnight in the fridge.

Fun fact: the flavors actually deepen a bit after a day or two, making it even tastier the next day. So, if you’re not in a rush, baking ahead can be a secret weapon for flavor development.

This recipe can be adapted to be gluten-free or dairy-free, accommodating various dietary needs.
