Cinnamon Toast Crunch Bar Ingredients

  • Marshmallows: You’ll need both jumbo marshmallows (to melt with the butter) to bind the bars and miniature marshmallows for delightful pockets of gooeyness.
  • Unsalted Butter: Butter might seem like a simple ingredient, but it’s essential for flavor and richness, preventing the bars from being overly sweet.
  • Cinnamon Toast Crunch Cereal: The star of the show! A store-brand cereal is fine, or you can experiment with variations like Chocolate Toast Crunch or Dulce de Leche Toast Crunch. Avoid Cinnamon Toast Crunch Churros, as the shape doesn’t work well for bars.

How to Make Cinnamon Toast Crunch Cereal Bars: Step-by-Step

Step 1: Prep the Pan

Lightly coat a 9 x 13 inch pan with non-stick cooking spray, making sure to cover the corners and sides.

Step 2: Melt Butter and Marshmallows

In a large pot, combine the jumbo marshmallows and butter. Heat over medium-low heat.

Why Are My Cereal Bars Hard?

A common mistake is cooking the marshmallow mixture at too high a temperature. Always melt the butter and marshmallows over medium-low heat. Slow and steady is key; avoid increasing the heat to speed things up.

Another mistake is pressing the mixture too firmly into the pan. Avoid packing the mixture tightly to prevent hard bars.

Step 4: Combine and Stir

Remove the pot from the heat and add the Cinnamon Toast Crunch cereal. Keep stirring until the cereal is fully coated. Then, add the mini marshmallows. Note: It’s important to add the mini marshmallows after the cereal has been stirred in. Adding them earlier can cause them to melt due to the mixture’s warmth.

Step 5: Press and Cool

Pour the mixture into the prepared pan immediately. Gently press down to flatten it. Consider spraying your hands with non-stick cooking spray for easier handling, or use the butter wrapper (butter-side down) to press the bars. Avoid pressing too hard to prevent tough bars.

Tips for Perfect Cinnamon Toast Crunch Treats

Here are a few secrets to help you achieve the best marshmallow-based bars, including these Cinnamon Toast Crunch bars, as well as the best Rice Krispie treats and Fruity Pebbles treats!

  • Tip #1: Grease your pan and your hands. This will make pressing the bars easier and prevent sticking. And if you don’t grease your hands, you’ll have to lick them—which is also a win!
  • Tip #2: Don’t press the bars too firmly. Gently press down to create an even layer, but avoid packing them tightly. This will prevent the bars from becoming tough.
  • Tip #3: Extra marshmallows are key! Adding mini marshmallows to the cereal provides fun pockets of marshmallow and contributes to the bars’ lightness, preventing them from becoming too dense.

Follow these steps, and you’ll achieve no-bake perfection every time!

Variations on Cinnamon Toast Crunch Bars

  • Add Caramel: Incorporate caramel bits (the kind sold near the chocolate chips) into the cereal and marshmallows for added gooeyness.
  • Muffin Tin Bars: Instead of making bars in a pan, make individual portions by using a well-greased muffin pan.
  • Elevate with Chocolate: Drizzle melted white chocolate over the cut bars for an extra touch of deliciousness.

Storage & Reheating Suggestions

Room Temperature: Cinnamon Toast Crunch bars tend to harden over time. Enjoy them as soon as possible! Store them wrapped in plastic wrap or in an airtight container for up to 3 days.

Freeze: Surprisingly, you can freeze cereal bars! Wrap the bars in plastic wrap, then place them in an airtight container or freezer bag. They’ll keep for up to 3 months in the freezer. Thaw at room temperature before eating. (You can also eat them straight from the freezer—trust me on this.)
