These are some must-have chillout treats on hot summer days:

Yarnell's ice cream sandwich (vanilla ice cream, chocolate cookie crust) at Dollar Tree, $1.

Soft-serve ice cream at Sonic, a giant serving (enough to share) for $1.

Fruit (mostly strawberries and blueberries) and yogurt (regular vanilla yogurt, not frozen, but it's plenty cold and refreshing) parfait, complete with a sprinkling of granola, at McDonald's, $1.

Blue Bunny Big Mississippi Mud ice cream sandwich (chocolate ice cream, chocolate cookie crust) from the Frosty Treats ice cream truck that cruises around town, $2.50

An ice cream float (two scoops and the soda of your choice) from FourSquare Gifts, 405 President Clinton Ave. in the River Market, $3.

A small (five ounces) serving of frozen yogurt -- nonfat, gluten-free, with lots of calcium and protein -- in yummy flavors like pomegranate and Madagascar vanilla from Red Mango, $2.99 (but you can probably find a coupon on the counter for $1 off).
