These are very easy to make and even easier to devour. Just stir everything in a small bowl and freeze overnight, then cut into bars, sandwiched between graham crackers. With the fat-free yogurt and large dose of fruit, these could be a healthy snack, a healthy dessert, or even a treat at breakfast. You can skip the graham crackers and eat the bars on their own, too — though your fingers will get cold and you won’t get the fun crunch of the crackers.

I adapted the recipe from this one at WW. I used a larger pan, because it made for thinner pieces that were easier to bite into. I added the graham crackers on a whim.

Makes 6 sandwiches

1 lemon
1 cup fat-free vanilla yogurt (I have used both Greek yogurt and a mixture of Greek with regular yogurt)
1 Tbsp. agave syrup
1 cup fresh blueberries
13-14 graham cracker rectangles

Line an 8×8-inch pan with parchment paper that hangs off the sides, so you can easily lift the yogurt out later.

Zest and juice the lemon. You need 1/2 tsp. of zest and 1/2 tsp. of juice. Mix the zest and juice into the yogurt with the agave syrup and blueberries.

Crush 1-2 graham cracker rectangles (amount depends on your preference). Spread half the crumbs onto the parchment, then spread the yogurt mixture evenly on top. Scatter the rest of the crumbs over the yogurt, pressing down gently, if possible, to make sure it all adheres.

Freeze overnight. When ready, lift it out of the pan and cut into six bars. Sandwich each bar between two graham cracker rectangles. Enjoy.
