Strawberry Sheet Cake

PREPARATION
Preheat oven to 350º F and lightly grease a 9×13-inch baking dish or a jelly roll baking sheet.
In a medium bowl, whisk together cake flour, baking powder, baking soda and salt.
In a large bowl or mixer, cream together butter and sugar for 3-4 minutes, or until fluffy and lightened in color.
Beat in egg whites, Greek yogurt and vanilla extract, then gradually mix in dry ingredients and milk, being careful not to over-mix.
Fold in diced strawberries, then transfer batter (it will be thick) to 9×13 or baking sheet.
Place in oven and bake for 30-40 minutes (if using 9×13) or 12-16 minutes (if using baking sheet), or until toothpick inserted in center comes out clean.
Remove from oven and let cool completely.
While cake bakes, start frosting by beating cream cheese and butter in a large bowl or mixer for 2-3 minutes, or until fluffy.
Add powdered sugar 1 cup at a time, until fully incorporated, then slowly mix in lemon juice.
Once combined, mix in fresh, diced strawberries until thoroughly incorporated.
Once cake has fully cooled, spread frosting on in a nice, even layer, then slice, serve and enjoy!
