Making this strawberry vanilla cake is effortlessly straightforward and perfect for bakers of all skill levels. Start by preheating your oven to 350°F and greasing and flouring two 8 or 9-inch cake pans to facilitate easy release after baking.
Prepare the 1 (18 1/4 ounce) box French vanilla cake mix exactly as directed on the package—this typically involves combining the mix with eggs, oil, and water, then beating until smooth. Divide the batter evenly between your prepared pans and bake according to the box instructions until a toothpick inserted in the center comes out clean.
Once your cake layers have cooled completely, the assembly process creates the signature strawberry-vanilla flavor combination. Place one cake layer on your serving platter, then transfer 1/4 cup of the 1 (15 ounce) can vanilla frosting into a piping bag or zip-top baggie with a corner snipped off.
Pipe this frosting around the outer edge of the bottom layer, creating a border that will contain the filling. Fill the center space with the 1/3 cup strawberry jam, spreading it evenly within the frosting border. Carefully place the second cake layer on top, pressing gently to secure.
Finish by spreading the remaining vanilla frosting generously over the top and sides of the assembled cake, creating smooth, even coverage. Complete your masterpiece by arranging fresh strawberries on top as garnish—you can slice them, leave them whole, or create decorative patterns depending on your preference.
The contrast between the white frosting and vibrant red berries makes for a stunning presentation that’s as beautiful as it is delicious.
