Preheat the oven to 350°F, and grease a 9x13-inch pan.
In a large mixing bowl, use a hand mixer to combine the cake ingredients. Mix until combined but don’t overmix the batter.
15.25 ounces white cake mix, 1 cup water, 3 large eggs, 3.4 ounces vanilla instant pudding, ¾ cup sour cream, ½ cup vegetable oil, 4 ounces lemonade mix, 2 teaspoons pure vanilla extract
Transfer the batter to the prepared pan, and bake for 30 to 40 minutes. A toothpick inserted in the center should come out clean.
To Make the Lemon Glaze:
Whisk together the sweetened condensed milk and lemon juice. Don't let this mixture sit too long, because it firms up.
1 cup sweetened condensed milk, ½ cup freshly squeezed lemon juice
When the cake comes out of the oven, pour the mixture over the warm cake. Smooth it into an even layer.
Let the cake cool completely before adding the buttercream.
To Make the Strawberry Buttercream:
Place the strawberries into a food processor (or blender) and process until smooth. Pour the puree through a mesh strainer to remove the seeds.
1 cup fresh strawberries
Use a hand mixer to combine the powdered sugar and softened butter. Slowly begin to add in the strawberry puree until the frosting reaches the desired consistency.
4 cups powdered sugar, 1 cup unsalted butter softened
Frost the cooled cake and add lemon or strawberry slices. Enjoy!
