**Recipe Adjustment** I’ve adjusted the basil filling recipe just slightly from my video recipe!

Strawberry Basil Flavor

Strawberry and basil together is the newest culinary flavor twist. I previously made Strawberry Basil Eclairs and Strawberry Basil Cupcakes and both times I was blown away with the flavor! It’s so unique and different, yet it works so well for desserts! To add the most basil flavor, I use a whole bunch of fresh basil for the filling combined with confectioner’s sugar. It makes for a sweet and herbaceous filling!

Strawberry Cake Layers

For the strawberry cake layers, I used my ‘Basic Vanilla Cake’ recipe, then added the strawberry flavor. This basic vanilla cake recipe is great for so many different recipes – just add extracts, fruit preserves, chocolate or other fillings. For my strawberry basil cake, I used chunky strawberry preserves and a bit of strawberry emulsion. This concentrated extract also includes color, which is perfect for this recipe. I use this Lorann Oils Strawberry Emulsion (affiliate link).

Strawberry Buttercream

The strawberry emulsion is also great for adding tons of strawberry flavor to the buttercream. Adding certain flavors to buttercream can be tricky and this is especially true with fruity buttercream recipes. Adding too much liquid or acid to a buttercream can cause it to break or separate. For this strawberry buttercream, I added just enough strawberry preserves to add the appearance of strawberry, then added the emulsion to add the flavor. It’s important to add the preserves at the very end of the recipe. First, make the buttercream super light and fluffy, then add the preserves and mix just until combined, about 15 to 20 seconds.

Making the Basil Filling!

This unique and herbaceous filling is the perfect complement to the berry cake layers! The basil filling is best if used right away; I recommend waiting to make it until the layers are cooled. Place the basil and confectioner’s sugar into a food processor. Pulse the basil and sugar together for a few minutes, until a thick paste forms. In a separate bowl, whisk the chilled heavy cream until stiff peaks form, about 4 minutes. Add the basil paste and whisk again for 20 to 30 seconds, until well incorporated.

16 servings
Delicate strawberry basil cake with strawberry cake layers, basil cream filling and strawberry buttercream!

Ingredients 

For Strawberry Cake:

  • 1 cup unsalted butter, softened
  • 1 cup white granulated sugar
  • 2 tsp vanilla extract
  • 6 egg whites, or 4 large eggs
  • 1 cup whole milk, or buttermilk
  • 2 cups all-purpose flour
  • 4 tsp baking powder
  • 1/4 tsp salt
  • 3/4 cup chunky strawberry preserves
  • 1 tsp strawberry extract or emulsion

For Basil Filling:

  • 1 medium bunch basil
  • 1 cup confectioner's sugar
  • 1/2 cup heavy whipping cream, chilled

For Strawberry Buttercream:

  • 2 cups unsalted butter, softed
  • 2 cups confectioner's sugar
  • 2 tbsp strawberry preserves
  • 1 tsp strawberry extract or emulsion

For White Chocolate Ganache:

  • 1/4 cup whole milk or cream
  • 3/4 cup white chocolate chips
  • 1 tsp shortening
  • fresh strawberries, for garnish

Instructions

For Strawberry Cake:

  • Preheat the oven to 350F/177C and line two, 8-inch (20-cm) cake rounds with parchment paper.
  • In a large mixing bowl, beat together softened butter, sugar and vanilla until fluffy. Add the egg whites or eggs and beat again until creamy and smooth. Using only egg whites yields a more 'white' cake; using whole eggs will give the cake a soft yellow color. Next, pour in the milk (I recommend using warm milk).
  • In a separate bowl, combine all the dry ingredients: flour, baking powder and salt. Sift the dry ingredients into the cake batter and whisk by hand to avoid over-mixing the batter.
  • To the finished batter, add the strawberry preserves and the strawberry emulsion. Fold the preserves gently into the batter, then divide it evenly between the two prepared pans. Bake the layers in the preheated oven for 28 to 30 minutes. Allow the layers to cool completely before assembling the cake.

For Strawberry Buttercream:

  • For the strawberry buttercream, place the softened butter into a mixer bowl and whisk on high speed for 5 to 6 minutes, until the butter is light and white in color. Add the confectioner's sugar and whisk again for a few minutes. Once the buttercream has reached the perfect consistency, add the strawberry preserves and emulsion. Whisk again but just until the strawberry is incorporated, about 20 seconds. Transfer 1 cup of the frosting into a pastry bag tipped with any star tip.

For Basil Filling:

  • The basil filling is best if used right away; I recommend waiting to make it until the layers are cooled. Place the basil and confectioner's sugar into a food processor. Pulse the basil and sugar together for a few minutes, until a thick paste forms. In a separate bowl, whisk the chilled heavy cream until stiff peaks form, about 4 minutes. Add the basil paste and whisk again for 20 to 30 seconds, until well incorporated.

Assembling the Cake:

  • To assemble the cake, use a long serrated knife to slice each layer in half, creating 4 layers total. Spread a few tablespoons of the strawberry buttercream onto each layer, then pipe a barrier ring of frosting around the edge of the layer. Fill the center with a generous amount of the basil whipped cream. Repeat this process for the remaining layer, then frost the outside with the remaining strawberry buttercream. Place the cake into the refrigerator to set while preparing the white chocolate glaze.
  • For the white chocolate ganache, combine the milk/cream, 1/2 cup of the chocolate and the shortening in a microwave-safe bowl or measuring cup. Heat for 1 minute, then stir until the chocolate is melted. Add the remaining 1/4 cup chocolate chips to help cool down the ganache. Allow the ganache to cool for about 15 to 20 minutes, until it's thick enough to pour onto the cake.
  • Pour the glaze over the chilled cake, nudging it gently over the side with a spatula. Garnish the top of the cake with fresh strawberries, dollops of cream and silver pearls. Keep cake refrigerated if not serving the same day. Remove the cake at least 1 hour prior to serving to allow the cake to thaw.
