Preheat oven to 350°F. Prepare a half sheet pan (18x13") with nonstick spray.
In a large bowl or stand mixer, cream the butter and sugar together until light and fluffy, about 3-4 minutes.
Add the eggs one at a time, beating well after each addition.
Mix in the lemon juice, lemon zest, and vanilla extract.
Gradually add the dry ingredients to the wet ingredients, alternating with the milk and mixing until just combined. Pour the batter into the prepared baking dish and smooth it out with a spatula.
Drop fresh blueberries evenly over the top. Bake 20-25 minutes or until a toothpick inserted in the center comes out clean. Cool completely.
Gather ingredients for the icing.
In a large mixing bowl, cream the butter and cream cheese together until light and fluffy, about 3-4 minutes.
Gradually add the lemon juice, lemon zest, milk, and powdered sugar, 1 cup at a time, mixing until smooth and creamy.
If the frosting is too thick, add a little more lemon juice or milk to thin it out. If it's too thin, add more powdered sugar until it reaches the desired consistency.
Once the cake is cool, spread the frosting over the top of the cake using a spatula or knife.
Decorate the cake with additional lemon zest or fresh blueberries, if desired. Serve and enjoy your delicious lemon blueberry sheet cake with lemon cream cheese frosting.
