They’re chewy, crispy, and irresistible—perfect for both kids and adults who grew up loving the cereal. Let’s dive into the easiest way to turn your favorite breakfast cereal into a crave-worthy dessert bar.

Ingredients Overview

Here’s a closer look at what makes these bars so simple and satisfying:

• Cinnamon Toast Crunch Cereal (6 cups)
  The star of the show. Provides cinnamon flavor and crunch. Lightly press—not crush—the cereal for the best texture.

• Mini Marshmallows (1 10-oz bag / about 5 1/2 cups)
  Melted marshmallows bind the bars and give that classic gooey chew. Mini marshmallows melt faster and more evenly.

• Unsalted Butter (4 tbsp / 1/2 stick)
  Adds richness and helps melt the marshmallows smoothly. Salted butter can be used for a sweet-salty contrast.

• Vanilla Extract (1 tsp)
  Boosts flavor and pairs beautifully with the cinnamon sugar.

• Optional Add-ins:

  • White chocolate chips for a creamy touch

  • Cinnamon chips for extra spice

  • A pinch of salt to balance the sweetness

  • Crushed cereal on top for texture and presentation

Ingredient Substitutions

• Vegan Version: Use vegan marshmallows and dairy-free butter.

• Nut-Free Option: This recipe is naturally nut-free—just check marshmallow brand labels to be sure.

• Lower Sugar: Reduce marshmallows slightly and press cereal into the pan loosely for a lighter bite.

Step-by-Step Instructions

1. Prepare Your Pan

Grease a 9×13-inch baking dish with butter or nonstick spray. For easy removal, line with parchment paper and leave a little overhang on the sides.

2. Melt Butter and Marshmallows

In a large nonstick pot, melt the butter over low heat. Add mini marshmallows and stir continuously until fully melted and smooth.

Tip: Stir gently to avoid stiff, rubbery bars later.

3. Add Vanilla

Remove from heat and stir in the vanilla extract.

4. Mix in Cereal

Immediately add Cinnamon Toast Crunch cereal to the marshmallow mixture. Use a silicone spatula or buttered spoon to gently fold until the cereal is fully coated.

Don’t over-stir—this helps preserve the crunch.

5. Press Into Pan

Transfer the mixture into your prepared pan. Lightly press the mixture into an even layer using greased hands, a buttered spatula, or wax paper. Don’t compact it too tightly or the bars will be hard.

Optional: Sprinkle a handful of cereal on top for texture and visual appeal.

6. Cool & Cut

Let the bars cool at room temperature for 30–45 minutes. Once set, lift from the pan and slice into squares or rectangles with a sharp knife.

Tips, Variations & Substitutions

Pro Tips

• Use fresh marshmallows: Stale marshmallows don’t melt well and can affect the texture.

• Low heat is key: Melting slowly prevents the marshmallows from becoming tough or sticky.

• Grease everything: Your spoon, your hands, even the parchment—this is a sticky recipe!

Flavor Variations

• S’mores Style: Mix in mini chocolate chips and drizzle with melted chocolate after pressing into the pan.

• Spicy Kick: Add a dash of cayenne or use a cinnamon-spice cereal blend.

• Fall-Inspired: Add a pinch of pumpkin pie spice and top with crushed graham crackers.

Make-Ahead Tips

• Make these up to 3 days ahead. Store tightly covered at room temperature.

• Avoid refrigerating—this can dry them out or make them overly hard.

Serving Ideas & Occasions

Cinnamon Toast Crunch bars are ideal for:

• Back-to-school snacks – Quick to pack and easy to make in big batches.
