Tips for Success:
- Read through all the ingredients and instructions so you can get a better idea of how much time and what you need to make this cake.
- A single batch of this cake recipe makes three, 6-inch round cake layers or two 8-inch round cake layers. Double the cake recipe to make enough cake batter for three, 8-inch cake layers.
- In this cake recipe, you need ½ cup buttermilk; if you don’t have any buttermilk on hand, you can easily use ½ cup whole milk mixed with 2 teaspoon lemon juice or white vinegar to make your own.
- To make cake flour at home, mix 2 ¾ cups all-purpose flour and ¼ cup cornstarch. Sift or whisk together to get rid of any lumps.
- Be careful not to overmix this cake batter, or else the cake will come out dense. Mix until all ingredients are well incorporated.
- You can bake the cake layers ahead of time. Wrap the cake layers in plastic wrap and freeze up to one month.
- You can make the buttercream, lime curd filling, and tequila syrup a day ahead and refrigerate them overnight. Then take them out to come back to room temperature. Make sure the buttercream is at room temperature before re-whipping.
- Serve at room temperature and enjoy!

Here’s how to make this sweet and decadent strawberry margarita cake!
Let’s Get Started!
Light & Fluffy Strawberry Cake
- Preheat the oven to 325 °F. Spray three 6-inch round cake pans with non-stick spray, line the bottom of each pan with parchment paper and spray again. Set aside.
- In a food processor, pulse fresh or frozen strawberries for 1 minute until cut into small pieces, then add strawberry jam and buttermilk, pulse until combined. Set aside.
- In a medium-size bowl, whisk and stir together the cake flour, baking powder, and salt. Set aside.
- In the stand mixer bowl fitted with a paddle attachment, beat the butter, oil, and sugar on medium-high for 5 minutes.
- Add the eggs, one at a time to the stand mixer bowl and beat on medium until well incorporated.
- Turn the mixer on low and add half of the flour mixture to the butter mixture then add buttermilk. Add in the remaining flour mixture and until fully incorporated.
- Pour in the strawberry mixture, vanilla extract, lemon juice, and zest. Mix on medium for another 30 seconds and add a few drops of super red gel food coloring. Mix until combined, then scrape down the sides of the bowl.
- Evenly distribute the cake batter among the three cake pans and bake for about 40-45 minutes or until a toothpick inserted into the center of each cake comes out clean or with just a few moist crumbs.
- Remove cakes from oven and let cool in pans for 10 minutes before inverting onto cooling racks to cool completely — wrap cakes in plastic wrap and place in the freezer to chill for at least 30 minutes.
How to Make Zesty Lime Curd
- In a medium saucepan, whisk together the eggs, egg yolks, sugar, lime zest, and lime juice. Continue whisking over low-medium heat until the sugar has dissolved.
- Add the cold butter cubes pieces at a time, stirring with a rubber spatula until each addition is melted and incorporated.
- Continue cooking the mixture for 4-5 minutes until it is thickened and coats the back of a spatula. Press plastic wrap directly onto the surface to prevent a skin from forming. Set aside to fully cool.
How to Make Tequila Syrup
- In a small saucepan, combine the sugar and water over medium heat. Continue to heat for 5 minutes until the sugar has fully dissolved. Remove from the heat and add the tequila. Set aside to cool.
Strawberry Lime Gel for Flavorful Buttercream
- In a small saucepot, add the fresh or frozen strawberries. Place pot over medium heat for 5-10 minutes to bring to a boil and break down the berries occasionally stir to prevent from burning on the bottom.
- In a small bowl, combine the cornstarch and water. Mix with a spoon until the mixture is lump-free. Add the mixture to the boiling strawberries, stirring constantly.
- Add lime zest to the strawberry mixture should be opaque and thick. Once thick, remove from the heat and place into the freezer to cool quickly.
Creamy Strawberry Lime Buttercream
- In the stand mixer bowl fitted with the paddle attachment, beat the butter until light and fluffy, about 2 minutes.
- Turn the mixer to low and add the cold strawberry gel, lime juice, salt, and vanilla.
- Next, gradually add powdered sugar, followed by the tequila. Mix on medium-high speed for about 5 minutes, until light and fluffy. Scrape down the sides of the bowl.
- Before using, turn the mixer on low and mix for 2 minutes to push out any air bubbles or use a rubber spatula to push out the air bubbles. (You may need to repeat this step when frosting the outside of the cake).
Putting It All Together
- Remove the cake layers from the freezer and unwrap the cake layers. Next, use a serrated knife to cut off the dome of the cakes to make the layers flat and even.
- Add a small amount of buttercream onto the center of the cake board.
- Layer a chilled strawberry cake, cut side up onto the cake board. Place a thin layer of buttercream on top of the cake then pipe a ring of buttercream. Add 1/4 cup of lime curd inside the circle of buttercream.
- Place another cake layer cut side down over the top. Repeat the process for another layer—Crumb coat and freeze for 30 minutes.
- Then add a thicker layer of frosting and smooth the sides out using an offset spatula and cake scraper.
- While turning the cake, use an offset spatula press and move your offset spatula from the bottom to the top holding the offset spatula perpendicular to the cake.
- Finally, add the strawberries, lime wedges, and sprinkle sea salt on top.
