Lemon is definitely a flavor of summer. Just think of sipping a glass of lemon on a nice hot summer day. I remember as a young girl coming in from being outside on a hot summer day for lunch. My mom would have lemonade made from concentrate waiting for me. I would lie on the floor near our swamp cooler to feel the cool air and sip my lemonade.

One of my favorite flavors is lemon and I usually have a lemon week each year just to focus on lemon recipes. I do have that coming up but had to include this cake recipe in my treats for a crowd week.

This lemon sheet cake is moist and flavorful. It is also topped with a sweet yet tangy lemon frosting! It is loaded with luscious lemony goodness that makes my mouth smile! Top it with some berries to make it even more amazing. If you serve it for the 4th of July top some with strawberry halves and some with blueberries to give it a festive look!
