DIY: AMERICA CUBED by @RuthlessCrafts

The 4th of July is this weekend and I wanted to share this tasty cubed treat with you that’s simple to make and fun to eat. My mom only ever made 2 flavors; grape juice and orange juice and they were delicious! I had fun picking out different colored juices to use with this DIY and I also picked up some orange and grape juice for old times’ sake. Let’s get started!

Here’s what you’ll need:

Skill Level: Beginner
Time: 2.5-3 hours

4 envelopes Knox Gelatine per batch
12 oz Fruit juice (frozen concentrate preferred) per batch
9×9 pan/s
Measuring cup
2 cups water per batch
Cooking spray
Mixing bowl/s

The recipe for Knox Blox is on the back of the box; my mom used a variation of their recipe. Essentially she removed 1 cup of water from the Knox version of the recipe so there is more concentrated flavor.

Thaw the frozen juice. I forgot to pull mine out as planned but I set it in the sink and it fully thawed in about 20 minutes. Boil 2 cups water in a saucepan. In your mixing bowl, combine the thawed juice along with 4 envelopes of Knox Gelatine; stir to immerse the gelatin and then let it sit while your water comes to a boil.

Lightly grease your 9×9 pan and set near the saucepan for convenience. Make sure there’s room in your fridge to place the 9×9 pan once full. Once the water is boiling, combine the fruit juice-gelatin mixture and stir until the gelatin is dissolved. Using this method it took about 1-2 minutes to fully dissolve. I poured the fruit juice and gelatin into my saucepan as I wasn’t sure if my mixing bowl could handle boiling water. Once fully dissolved, carefully pour the mixture into the pan. Pour slowly and there won’t be any splash-back; gelatin is sticky but can be cleaned with a hot, wet rag. Place the pan in your fridge and let it set; about 2-3 hours.



Once set, cut into cubes and lay on your serving tray. I put some parchment paper down first.


For the non-frozen juices, follow the same instructions. I chose strawberry cocktail for red, coconut puree (in the drink mix aisle!) for white and Sunny D Blue Raspberry. I was hoping to find blueberry juice but no dice. Sadly, the Sunny D cubes didn’t turn out so much in flavor but the strawberry and coconut were amazing! Funnily enough, the coconut puree settled at the top and the syrup in the can settled at the bottom creating a two-toned Knox Blox. If you want a pineapple flavor, my mom advises to use canned juice as fresh pineapple juice contains an enzyme that will break down the protein in the gelatin causing it not to gel (she’s well-versed when it comes to food chemistry!)

I meant to pick up a star cookie cutter but forgot so I cut the stars out by hand. The 1st ones weren’t so great but I got much better as I went along. The two-toned gelatin made it much easier for me to split them in half! Place the cubes in your desired pattern and refrigerate until served.


There are so many different kinds of cubes you could make; let your imagination run wild! Have any great ideas on ways you can make this DIY your own? Tell me in the comments below!
