This 3-Ingredient Blueberry Dessert Is Straight Out of My Grandma’s Recipe Box

Unmold the Jell-O:

To unmold the Jell-O, fill a large bowl of water about halfway with warm (not boiling hot) water, then dip the mold into the water for about 10 seconds. Remove the mold from the water, place a serving plate on top, and carefully flip it over. If the Jell-O doesn’t unmold, try another 10-second dip and attempt to flip it once more. Repeat until the Jell-O slides out easily onto the serving plate.
Simple Tip!

If you’re having trouble releasing the dessert from the mold, you can also gently slide a small offset spatula or butter knife down the side of the mold to break the suction, which should allow it to slide out.
Serve:

Use a cake server to cut the Jell-O mold into slices, transfer to serving plates, and serve right away.

Cover leftovers tightly with plastic wrap and refrigerate for up to 3 days.
