Ingredients for chex powdered sugar chocolate
Six crispy cups of cereal meet two cups of velvety chocolate magic—textures that shouldn't mix but do perfectly.
| Ingredient | Amount | Notes |
|---|---|---|
| Corn Chex Cereal 🍞 | 6 cups | Original flavor, not honey-nut |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for even baking |
| Granulated Sugar 🍚 | 1 cup | White or light brown |
| Powdered Sugar 🍬 | 1 cup | Confectioners' sugar, sifted |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality |
| Semisweet Chocolate Chips 🍫 | 2 cups | High-quality, 60% cocoa |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat for richness |
| Salted Butter 🧈 | ¼ cup | Melted for chocolate layer |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain for balance |
| Unsweetened Cocoa Powder 🍫 | ¼ cup | Natural, not Dutch-processed |
The cereal is non-negotiable—Corn Chex (not Honey Nut) gives that signature crunch. Grab the original flavor from any grocery store; it's the same stuff that's been winning hearts since the '50s. For the chocolate, Ghirardelli or Guittard chips make all the difference—avoid the grocery store generic brands. The powdered sugar? Confectioners' sugar is a must; it dissolves smoothly and adds that signature sweetness without graininess. If you're in a pinch, Duncan Hines works fine, but your local bakery supply store will have the good stuff.
No vanilla extract? Almond extract at half the amount works in a bind, but trust me—pure vanilla is worth the splurge. Swapping chocolate chips? Dark chocolate bars (70% cocoa) melt beautifully—just chop them finely. The cocoa powder is optional, but it deepens the chocolate flavor if you're feeling fancy. For the butter, European-style (like Plugrá) has more fat, so you might need slightly less. And if you're watching calories? Light butter works, but the texture won't be quite as rich. The cream? Full-fat only—this isn't the time for skim.
Prep the cereal base ahead—it keeps well for 2 days in an airtight container. The chocolate layer? Make it the night before and refrigerate; it'll be easier to spread. Once baked, these bars stay fresh for 5 days at room temperature if you keep them sealed. For gifting, wrap individual bars in parchment paper and tie with twine—looks fancy, takes 2 minutes. Freezing? Not recommended—the cereal loses its crunch. But if you must, freeze for up to 1 month in a single layer before transferring to a container.

Step-by-step instructions for Chex powdered sugar chocolate bars
Here's how to create the perfect balance of crispy cereal and rich chocolate layers.
Prepare the Crunchy Cereal Base
Preheat your oven to 350°F and line an 8x8-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. In a large bowl, combine the 6 cups Corn Chex Cereal with the 1 cup Granulated Sugar and 0.75 cup Unsalted Butter, which should be cold and cubed. Mix gently until the butter begins to melt and evenly coats the cereal.
Spread the mixture into the prepared baking pan, pressing down firmly and evenly with a spatula. Bake for 12-15 minutes until the cereal is golden and crispy. Keep an eye on it—it should be just starting to turn golden brown, not dark brown. Let the base cool completely in the pan before proceeding. This step ensures your bars have that perfect crunchy foundation that holds up to the gooey layers.
Create the Powdered Sugar Layer
While the cereal base cools, prepare the powdered sugar mixture. In a medium bowl, whisk together the 1 cup Powdered Sugar, 2 whole Large Eggs, 1 tsp Vanilla Extract, and 0.25 tsp Diamond Crystal Kosher Salt until smooth and fully combined. The batter should be thick but pourable—if it looks too stiff, whisk in a splash of milk or water to loosen it.
Once the cereal base has cooled completely, pour the powdered sugar mixture evenly over the top. Use a spatula to spread it out smoothly, making sure it reaches all the edges of the pan. Return the pan to the oven and bake for an additional 15-18 minutes until the top is set and lightly golden. You'll know it's ready when the center no longer looks wet and the edges pull away slightly from the pan. Let this layer cool completely before moving on.
Prepare the Chocolate Ganache
In a heatproof bowl, combine the 2 cups Semisweet Chocolate Chips and 1 cup Heavy Whipping Cream. Place the bowl over a pot of simmering water, ensuring the bottom of the bowl doesn't touch the water. Stir gently until the chocolate and cream melt together smoothly, creating a glossy, thick ganache. Remove from heat and let it cool slightly, but keep it warm enough to pour.
While the ganache cools, melt the 0.25 cup Salted Butter in a small saucepan over low heat. Once fully melted, stir it into the ganache along with the 0.25 cup Unsweetened Cocoa Powder. Mix until fully incorporated and smooth. The ganache should be thick but still pourable—if it sets up too much, gently reheat it for a few seconds. This step is crucial for achieving that rich, velvety chocolate layer that ties everything together.
Assemble and Set the Bars
Pour the chocolate ganache evenly over the cooled powdered sugar layer, spreading it out smoothly with a spatula. Use the overhanging parchment paper to lift the entire pan out of the baking dish and transfer it to the refrigerator. Let it chill for at least 2 hours, or until the chocolate is completely set and firm to the touch. This chilling time ensures the chocolate hardens properly and the layers stay intact.
Once fully set, use the parchment overhang to lift the bars out of the pan. Cut into 16 equal squares and serve at room temperature. The contrast of the crispy cereal base, the light powdered sugar layer, and the rich chocolate top creates a perfect bite every time. Store any leftovers in an airtight container in the refrigerator for up to 1 week, or freeze for up to 3 months for maximum freshness.
Pro Tips For Making Chex Powdered Sugar Chocolate
- TOAST THE CHEX FIRST: Pop the Corn Chex in a dry skillet over medium heat for 3-4 minutes—just until they smell nutty and toasted. I learned this the hard way after making a batch that tasted flat; the raw cereal soaks up too much butter and stays bland. Skip this, and your bars will lack that crunchy depth.
- USE ROOM-TEMP EGG WHITES: Let your eggs sit out for 30 minutes before separating them—whipped egg whites fold in smoother when they’re not cold. I used to rush this and ended up with dense, gummy bars. Trust me, the extra time makes the texture light and airy, especially when mixed with powdered sugar.
- STOP WHEN IT LOOKS DONE: Pull your bars out of the oven when the edges are set but the center still jiggles slightly—it’ll firm up as it cools. Overbaking turns them dry and crumbly. I used to leave them in until the center was firm, and they’d crack or taste like cardboard.
- SWAP POWDERED SUGAR HALFWAY: Mix half the powdered sugar into the wet ingredients first, then fold in the rest after baking. This keeps the bars from getting gummy while maintaining that signature sweetness. (Yes, it’s an extra step, but your future self will notice the difference.)

Frequently asked questions
Can I make these bars without an oven?
Unfortunately, this recipe requires baking to achieve the crispy cereal base and set powdered sugar layer. The chocolate ganache can be made stovetop, but the cereal foundation needs oven time to develop its signature crunch. For a no-bake alternative, try pressing the cereal into a pan with melted chocolate and refrigerating, though the texture won't be identical.
How do I prevent the cereal base from getting soggy?
Bake the cereal layer until it's golden brown but not dark—12-15 minutes at 350°F—and let it cool completely before adding the powdered sugar mixture. If your kitchen is humid, chill the pan for 10 minutes after baking to help it set faster. The key is ensuring the base is fully crisp before adding wet ingredients.
Can I use a different type of cereal instead of Corn Chex?
While Corn Chex is ideal for its neutral flavor and perfect crunch, you can experiment with other small, crispy cereals like Rice Chex or Corn Flakes. Avoid larger flakes (like Wheat Chex) or honey-nut varieties—they won't create the same texture. If substituting, reduce baking time slightly to prevent over-browning.
Why did my chocolate layer crack?
Cracking usually happens when the chocolate sets too quickly during chilling. To prevent this, let the ganache cool slightly before pouring (it should be warm but not hot) and avoid placing the pan in the freezer. If cracks appear, simply drizzle extra melted chocolate over the top before serving—it'll look intentional and delicious!
How can I make these bars nut-free for allergies?
This recipe is naturally nut-free, but if you're using store-bought chocolate chips, check the label for cross-contamination warnings. For extra safety, use a dedicated baking pan and utensils that haven't touched nuts. The powdered sugar layer and cereal base are both inherently nut-free, making this a great option for nut allergy concerns.
