Does baking soda make a difference in Cracker Jacks-Style caramel corn? Yes, but not in the way you might expect. While caramel corn made with and without baking soda looks nearly identical, the textures differ. Baking soda creates a lighter, more aerated coating, while omitting it produces a more cohesive, crisp texture found in Cracker Jacks.
There are some recipe ingredients that you add without thinking, and baking soda in the caramel mixture is one of them. For years, I've made caramel corn the same way: pop the corn, make the caramel, stir in baking soda, coat, bake, and enjoy. It works, it's reliable, and frankly, I never questioned it.
But then, I started wondering, what would happen if I simply left the baking soda out? Not change anything else - just change that one variable. So I ran a side-by-side test: same popcorn, same caramel base, same process, but one with baking soda and one without.
The results were not what I expected!

Chula's Test Kitchen
This was a controlled, single-variable test:
What stayed the same:
- Mushroom popcorn (for that Cracker Jacks look)
- Dark brown sugar (for color and depth)
- Dark corn syrup (for color and depth)
- Spanish redskin peanuts (used in Cracker Jacks)
- Baking method and temperature
What changed:
Baking soda was added to one batch of caramel and omitted from the other.
What Baking Soda Does in Caramel Corn
When baking soda is added to hot caramel, it reacts, creating tiny air bubbles. This lightens the caramel, creates a more porous coating, and produces a slightly "sand-like" texture.
Without baking soda, the caramel remains denser, coats the popcorn more smoothly, and produces a more cohesive crunch.
Test Results
Texture
- With baking soda: Lighter, slightly airy, more delicate
- Without baking soda: More cohesive, slightly denser, crisp
Appearance
- Surprisingly, almost identical. Both versions had similar color, similar coating, and similar visual appearance.
Taste
- The baking soda version seemed sweeter, likely due to the texture difference
- The no-baking-soda version tasted slightly more balanced
Baking Time
- The batch without baking soda required 15 minutes longer in the oven, likely due to a higher moisture retention in the denser coating.
Comparison to Cracker Jacks
- Cracker Jacks had significantly fewer peanuts (by design, I added significantly more peanuts to both versions)
- The flavor of Cracker Jacks was noticeably milder, almost bland
- The texture of the Cracker Jacks-style caramel corn was closer to commercial Cracker Jacks with the no-baking-soda version
Which Version Is Better?
As with many things, it depends on what you're looking for:
- If you want a lighter, more traditional caramel corn texture, use baking soda in the caramel.
- If you want something closer to the Cracker Jack-style texture, skip the baking soda in the caramel.
Ingredients for Cracker Jacks-Style Caramel Corn
- Popcorn: Mushroom popcorn popped in peanut oil versus the traditional store-bought butterfly-style popcorn for the Cracker Jack signature look.
- Peanuts: Redskin Spanish Peanuts for the Cracker Jack signature look - but I used a lot because this is my favorite part of Cracker Jacks!
- Caramel: Dark brown sugar, dark Karo syrup, unsalted butter, Kosher salt, and vanilla extract.
How to Make Cracker Jacks-Style Caramel Corn - Step-by-Step
- Pop the Corn: Use your favorite method to pop the corn. I used my Dash SmartStore Stirring Popcorn Maker with 2 tablespoons of oil and around ½ cup of mushroom popcorn.
- Popcorn and Peanuts: Add the popped corn to a large bowl, then place the peanuts on top. Do not stir at this point. Leaving the peanuts on tops is best for good coverage of the caramel.
- Make the Caramel: Melt the brown sugar, butter, corn syrup, and salt in a small to medium saucepan over medium-high heat, stirring occasionally. Once the mixture reaches a boil, reduce the heat to medium-low and cook, undisturbed, for 5 minutes. Remove the pan from the heat and stir in vanilla. Be careful because the mixture will bubble up.
- Coat the Popcorn and Nuts: Pour the caramel over the popcorn and nuts, and toss to coat.
- Transfer and Bake: Transfer the coated popcorn and nuts to a large disposable aluminum baking pan and spread them in an even layer. Bake at 250°F for 1 hour and 15 minutes, tossing every 15 minutes.
- Cool: After 1 hour and 15 minutes, remove the caramel corn from the oven and transfer it to a piece of parchment paper. Allow it to cool completely - the caramel corn will crisp up as it cools. Store in an airtight container.
This was one of those experiments that changed how I think about a "standard" Ingredient. Before, I had assumed that baking soda was a key ingredient in making the caramel for caramel corn. However, based on this experiment, it isn't required. Rather, it's a choice.
Depending on the texture that you're aiming for, skipping the baking soda will likely get you closer to the result you want.
Whatever your preference, this Cracker Jack-style caramel corn is addictively delicious, especially with the extra peanuts, so judge for yourself. Yum!
Tips for Success
- Use a large bowl to mix the popcorn and peanuts with the caramel for even coating.
- Stir the popcorn and peanuts with the caramel thoroughly, but don't worry if some of the popcorn isn't well coated. The baking and stirring will continue coating the popcorn.
- Bake low and slow for best texture.
- Don't judge by appearance alone - the difference is in the bite.
Frequently Asked Questions
No. Baking soda changes the texture, but it is not required. Caramel corn without baking soda will be denser and more cohesive.
Baking soda creates bubbles in the caramel, making the coating more porous and airy and resulting in lighter caramel corn.
The no-baking-soda version more closely matches the texture and flavor of Cracker Jack-style caramel corn.

Tips/Notes
- Mushroom popcorn is a variety that pops into large round balls as opposed to the "winged or butterfly" style of store-bought kernels. Based on appearance, commercial Cracker Jacks likely uses mushroom popcorn.
- I popped the kernels in my Dash Stirrig Popcor Maker with 2 tablespoons of peanut oil, but feel free to use your favorite method of popping popcorn.
- Based on appearance, commercial Cracker Jacks likely uses redskin Spanish peanuts. The peanuts are my favorite part of Cracker Jacks, so I added significantly more than the commercial variety uses.
- Dark brown sugar and dark Karo syrup produce a darker color and a flavor with more depth than light brown sugar and light Karo syrup.
- Not stirring the peanuts into the popcorn initially results in a better distribution during coating.
- The caramel mixture will bubble up when the vanilla is added, so be careful.
- Don't worry if not all of the popcorn is coated at this point. The baking and stirring during baking will take care of this.
- The reason that I like to use a large disposable aluminum pan is that it minimizes cleanup. This is a personal preference.
- The caramel corn will crisp up as it cools.
