Ingredients You Will Need

Focus on quality for the best texture. Cake flour ensures fluffiness, buttermilk adds tang, and fresh berries shine brightest.

Vanilla Cake Layers (Makes two 8-inch rounds)

• 2 and 1/3 cups cake flour, spooned and leveled (swap with 2 and 1/4 cups all-purpose minus 2 tablespoons plus 2 tablespoons cornstarch)
• 2 and 1/2 teaspoons baking powder
• 1/2 teaspoon baking soda
• 1/2 teaspoon salt
• 1/2 cup unsalted butter, softened to room temperature
• 1/2 cup vegetable or canola oil
• 1 and 3/4 cups granulated sugar
• 3 large eggs, room temperature
• 1 tablespoon pure vanilla extract
• 1 and 1/2 cups buttermilk, room temperature (or whole milk with 1 tablespoon lemon juice)

Oil keeps the cake moist longer than butter alone. Buttermilk tenderizes for that melt-in-your-mouth crumb.

Fresh Strawberry Filling

• 3 cups fresh strawberries, hulled and chopped (about 1 pound)
• 1/2 tablespoon granulated sugar
• 3 tablespoons fresh lemon juice
• 2 tablespoons cornstarch
• 2 tablespoons water (for slurry)

Cook this down for a thick, spreadable filling that soaks into the cake without sogginess. Lemon brightens the berry flavor.

Strawberry Buttercream Frosting

• 1 and 1/2 cups unsalted butter, softened
• 3 to 3 and 3/4 cups powdered sugar, sifted
• 1/4 cup cooled strawberry filling (from above)
• 1 teaspoon vanilla extract
• Pinch of salt
• 1 to 2 tablespoons heavy cream, if needed

The filling tints the frosting pink naturally. Start with less sugar and add for your preferred sweetness.

Step-by-Step Instructions

Follow these numbered steps for foolproof results. Preheat oven to 350 degrees F (177 degrees C). Grease and flour two 8-inch round pans, line with parchment.

Make the Strawberry Filling First

This needs time to cool, so start here.

1. In a medium saucepan over medium heat, combine chopped strawberries, sugar, and lemon juice. Cook for 5 to 7 minutes, stirring occasionally, until berries soften and release juices.
2. In a small bowl, whisk cornstarch and water into a slurry. Stir into the strawberry mixture. Simmer 2 to 3 more minutes until thickened like jam. Remove from heat.
3. Transfer to a bowl and cool completely in the fridge, at least 1 hour. It thickens more as it chills. Yields about 1 and 1/2 cups.

Pro tip: Taste and add a pinch more sugar if your berries are tart.

Bake the Vanilla Cake Layers

1. Whisk flour, baking powder, baking soda, and salt in a medium bowl. Set aside.
2. In a large bowl, beat butter, oil, and sugar on high speed 2 minutes until light and fluffy. Add eggs one at a time, beating well after each. Mix in vanilla.
3. On low speed, add dry ingredients in three parts, alternating with buttermilk. Begin and end with dry. Mix just until combined, about 20 seconds. Scrape bowl as needed. Batter will be thick.
4. Divide evenly between pans. Smooth tops. Bake 24 to 30 minutes, until toothpick in center comes out clean. Cool in pans 10 minutes, then invert onto wire racks. Peel parchment and cool fully.

Why this method? Alternating wet and dry prevents gluten development for tender cake.

Whip Up the Strawberry Buttercream

1. Beat butter on medium-high 2 minutes until creamy.
2. Add powdered sugar 1 cup at a time, beating on low then high until smooth. Scrape bowl.
3. Mix in 1/4 cup cooled strawberry filling, vanilla, and salt. Beat 2 minutes. If too thick, add cream 1 tablespoon at a time.

Frosting firms up in the fridge but softens at room temp. Perfect piping consistency.

Assemble Your Strawberry Vanilla Cake

1. Level cooled cake layers with a serrated knife if domed.
2. Place one layer on a serving plate or cake board. Pipe a buttercream border around the edge to dam the filling.
3. Spread 3/4 cup strawberry filling inside the dam. Top with second layer.
4. Apply thin crumb coat of buttercream over top and sides. Chill 10 minutes.
5. Frost fully with remaining buttercream. Smooth sides or pipe swirls on top. Garnish with halved strawberries.
6. Chill assembled cake 30 minutes before slicing for clean cuts.

For three layers, multiply cake batter by 1.5 and use 6-inch pans.

Essential Recipe Tips and Troubleshooting

Baking questions answered to save your cake.

Dense cake? Check that oven temp with thermometer; overmixing toughens it.

Runny filling? Simmer longer or add extra cornstarch slurry.

Frosting too soft? Chill beaters and bowl first, or refrigerate frosting 15 minutes.

Flat layers? Ensure baking powder fresh (test in water: bubbles).

Dairy-free version? Swap butter for vegan, buttermilk for almond milk plus vinegar, and skip heavy cream.

Make ahead: Bake/fill up to 2 days ahead (fridge). Frost day of. Or freeze unfrosted layers up to 3 months, thaw overnight.

Storage: Fridge airtight up to 5 days. Serve at room temp for best flavor. Not freezer-friendly once assembled due to fruit.

Delicious Variations to Try

Customize for fun.

Almond twist: Add 1/2 teaspoon almond extract to cake and frosting.

Three-layer drama: Use three 6-inch pans, bake 22 to 25 minutes.

Vegan: Replace eggs with 3/4 cup aquafaba (whipped stiff), use plant-based everything.

Chocolate accent: Drizzle ganache or add cocoa to half the frosting.

Mini cakes: Bake in 12 muffin tins 18 to 20 minutes, fill and frost tops.
