Lemonade Crumb Bars

If you love my Lemon Crumb Bars, you’re going to love this fun variation! These Lemonade Crumb Bars use frozen lemonade concentrate for an extra punch of bright, tangy flavor. They’re simple to make, with a creamy lemon filling and a soft, crumbly oat crust and topping. Great for summer or anytime you’re craving something sweet and citrusy.
