Need a new summer dessert? Try blueberry Rice Krsipie Treats, filled with juicy, fresh fruit!

All you need to do is add blueberries to our best-ever, 3-ingredient Rice Krispie Treat recipe.

can I add fresh berries to desserts?

Yes! You can. However, it's important to note the shelf life is shorter when you add fresh fruit to a dessert. Refrigerate and serve within 3 days. Blueberry cereal treats are delicious, so this shouldn't be a problem.

If you'd like your treats to last longer, you may substitute 2 ounces of crushed, freeze-dried blueberries instead, just as we did with this delicious strawberry Rice Krispie treat recipe.
