Who doesn't love a whoopie pie or an ice cream sandwich?! We've put them together for a fun and mouthwatering treat! Tender lemon poppy seed whoopie pies are filled with tangy lemon ice cream swirled with blueberry puree. They are so refreshingly delicious, especially on a hot summer day. Find out below the two easy ways we fill our ice cream sandwiches!

You can, of course, use (a good quality) store-bought ice cream to fill these whoopie pies, but we love using this homemade lemon-blueberry ice cream whenever possible.
