This strawberry sheet cake is soft, tender, and full of fresh strawberry flavor. With an easy batter and a creamy strawberry-speckled frosting, it’s a simple dessert that’s sure to impress!
Preheat oven to 350°F (175°C). Grease a 9"x 13"x 2" baking pan.
Whisk together the flour, sugar, baking powder, and salt. Make a well in the center.
In a separate bowl, whisk together the buttermilk, preserves, butter, eggs, and vanilla. Pour into the well in the flour mixture, and stir to combine. Stir in strawberries.
Pour the batter into the prepared pan and spread evenly. Bake 25 to 30 minutes, or until a pick inserted into the center comes out clean. Cool the cake completely on a wire rack.
To make the frosting:
Using an electric mixer on medium speed, beat the cream cheese and butter until thoroughly mixed and smooth. Gradually add the confectioners' sugar, mixing until combined. Stir in the strawberries.
Spread the frosting on top of the cooled cake. Refrigerate for at least 1 hour before serving. Refrigerate any leftovers.
Notes
*Add up to another 3/4 cup confectioners' sugar if you want a sweeter frosting.
Store tightly covered in the refrigerator up to a week.
