Homemade Pop Rocks: Sweet, Fizzy Fun You Can Make at Home

Ready to bring some explosive fun into your kitchen? These Homemade Pop Rocks are a nostalgic, fizzy candy treat that crackles and pops in your mouth—just like the store-bought version, but made from scratch! With a few pantry staples and a little science-inspired magic, you can create your own batch of popping candy for parties, desserts, or just for fun. This recipe is perfect for adventurous bakers, science lovers, and anyone who wants to wow guests with an unexpected, fizzy treat.

What Are Pop Rocks?

Pop Rocks are a type of hard candy that contains pressurized carbon dioxide bubbles. When the candy dissolves in your mouth, the bubbles burst, creating that signature crackling sensation. While commercial Pop Rocks are made with advanced technology to trap CO₂, this homemade version mimics the experience using citric acid and baking soda—a classic fizzy combo that delivers a satisfying pop and tang.

Ingredients

To make your own batch of homemade Pop Rocks, you’ll need:

1 cup granulated sugar
1/2 cup light corn syrup
1/4 cup water
1 tsp flavored extract (cherry, raspberry, orange, or your favorite flavor)
2–3 drops food coloring (optional, for a vibrant look)
1/4 tsp citric acid (adds the sour pop)
1/4 tsp baking soda (creates the fizz)

Tip: You can find citric acid at most grocery stores near canning supplies, or order it online.

Equipment You’ll Need

Candy thermometer
Medium saucepan
Parchment-lined baking sheet
Spoon or rolling pin (for crushing)
Airtight container (for storage)

Instructions

Step 1: Prepare the Baking Sheet

Line a baking sheet with parchment paper and lightly grease it with nonstick spray or a thin layer of oil. This prevents sticking and makes cleanup easier.

Step 2: Make the Candy Base

In a medium saucepan over medium heat, combine the sugar, corn syrup, and water. Stir constantly until the sugar dissolves completely. Once it does, stop stirring to avoid crystallization.

Step 3: Monitor the Temperature

Allow the mixture to boil undisturbed until it reaches 300°F (149°C) on a candy thermometer—this is known as the hard crack stage, and it’s essential for the right texture. This process takes about 10–12 minutes.

Step 4: Add Flavor and Fizz

Remove the saucepan from the heat. Immediately and carefully stir in the baking soda, citric acid, flavored extract, and food coloring. The mixture will foam and bubble—this is totally normal.

Step 5: Cool and Set

Quickly pour the bubbling mixture onto your prepared baking sheet and spread it out evenly. Let it cool completely until hardened (about 20–30 minutes at room temperature).

Step 6: Crush into Candy Shards

Once hardened, use a spoon or rolling pin to break the candy into tiny shards. The smaller the pieces, the more fizzy surface area you’ll create.

Step 7: Store and Enjoy

Transfer your homemade Pop Rocks to an airtight container. Store them in a cool, dry place to preserve their fizzy texture.

Note: Humidity will reduce the fizziness over time, so don’t leave them out for too long.

Safety Tip

This recipe involves hot sugar syrup, so always use caution when cooking and pouring. Keep children at a safe distance during preparation.
