In a medium-size bowl, combine strawberries, lemon juice, cornstarch and sugar. In a separate bowl, combine oats and Cheerios™ with brown sugar. Add butter and use your hands to mix it in. Distribute the strawberries evenly into 4 individual molds. Add the oats on top. Bake for 350ºF for 15-20 minutes or until the strawberries are caramelized and the oats are golden. Serve and enjoy!
