Rice Krispie Treats Recipe With Cinnamon Toast Crunch: Cereal Mashup With Crunchy Swirls

This cereal mashup takes classic Rice Krispie treats to a whole new level with bold cinnamon-sugar flavor. The combination of buttery marshmallow and crispy Cinnamon Toast Crunch creates an irresistible texture contrast that’s impossible to resist.

What makes this version special is how the cereal’s cinnamon coating melts slightly into the marshmallow mixture, while still maintaining its signature crunch. The result is a treat with layers of sweet, spiced flavor in every bite.

These come together in 15 minutes with just a few simple ingredients, making them perfect for last-minute gatherings or satisfying sudden cravings. The cinnamon adds warmth that pairs beautifully with the buttery richness.

Serve warm for gooey perfection or let them set for a firmer, sliceable treat. Either way, they disappear fast.

Ingredients for Rice Krispie Treats Recipe with Cinnamon Toast Crunch

A few pantry staples create this elevated twist on a nostalgic favorite with warm cinnamon notes.

The cereal quality matters here. Kellogg’s Rice Krispies and Cinnamon Toast Crunch deliver the right texture—store brand versions often lack the signature crunch. Use fresh marshmallows (check the date) as stale ones won’t melt properly. For the butter, Land O’Lakes unsalted is a reliable choice, but any high-quality brand works.

Out of Cinnamon Toast Crunch? Apple Cinnamon Cheerios can substitute in a pinch, though the flavor will differ slightly. No mini marshmallows? Large ones cut into quarters work, but melt them first. Want extra spice? Add an extra ½ tsp of cinnamon. The vanilla extract can be omitted, but it adds depth to the marshmallow mixture.

These keep well at room temperature in an airtight container for 3-4 days. For longer storage, freeze for up to 1 month—thaw before serving. Cut into squares once fully set for easy serving.

Step-by-Step Instructions for Rice Krispie Treats With Cinnamon Toast Crunch

This method ensures perfect texture and balanced flavor in every crunchy, gooey square.

Step 1: Melt Butter and Toast Marshmallows

In a large, heavy-bottomed pot, melt the 0.5 cup unsalted butter over low heat. I always use a pot with a light-colored interior so I can monitor the color change as the marshmallows toast.

Once melted, add all 10 cups mini marshmallows and stir constantly with a silicone spatula. After 2-3 minutes, the marshmallows will begin to melt and turn a light golden brown. Remove from heat immediately when you see this color change—this prevents burning and maintains that perfect toasted flavor.

Step 2: Incorporate Flavor Enhancers

Off the heat, stir in the 1 tsp ground cinnamon, 1 tsp vanilla extract, 0.25 tsp salt, and 0.25 cup granulated sugar. The residual heat will help distribute these ingredients evenly throughout the melted marshmallow mixture.

Mix thoroughly for 30-45 seconds until fully combined and the mixture appears uniform in color. The cinnamon should be completely dissolved, and you should see no streaks of vanilla or sugar. This step ensures every bite carries the full depth of flavor.

Step 3: Fold in Cereals for Signature Texture

Working quickly while the marshmallow mixture is still hot, add the 6 cups Rice Krispies Cereal and 3 cups Cinnamon Toast Crunch Cereal. I recommend adding them in two batches to ensure even coating.

Use the silicone spatula to fold gently until every piece of cereal is fully coated with the marshmallow mixture. You’ll notice the Rice Krispies begin to soften slightly while the Cinnamon Toast Crunch maintains its characteristic crunch. The mixture should hold together when pressed but still have visible cereal pieces.

Step 4: Press and Set in Pan

Transfer the mixture to a greased 9×13-inch baking pan. I line my pan with parchment paper for easy removal. Use the spatula or lightly buttered hands to press the mixture evenly into the pan.

Press firmly but don’t compact it too tightly—you want the treats to hold together but maintain some airiness. Let the pan sit at room temperature for 30-45 minutes until completely set and cool to the touch.

Step 5: Cut and Serve

Once fully set, use a sharp knife to cut into 2-inch squares. For clean cuts, I run the knife under hot water between each slice. The treats should have a glossy sheen on the surface with visible flecks of cereal throughout.

Serve at room temperature. Each square should offer the classic chewy-marshmallow base with distinct crunchy bits from the Cinnamon Toast Crunch. The cinnamon flavor will be noticeable but not overpowering, perfectly complementing the buttery sweetness.

Wine and Beer Pairings for This Recipe

Milk Pairings

Cold whole milk is my top choice—the creamy texture balances the sweetness while the cold temperature contrasts beautifully with the warm, gooey treats. A glass of chocolate milk takes it to the next level, creating a dessert experience that feels indulgent. 🥛

Coffee Companions

A hot cup of coffee cuts through the richness with its bitterness, making each bite taste even better. I prefer a medium roast with a splash of cream to complement the cinnamon notes. The warmth of the coffee alongside the treats is pure comfort.

Beer Options

For an adult pairing, try a cream ale like Sixpoint Sweet Action—its light sweetness and smooth finish work surprisingly well. A Brown Ale with caramel notes also enhances the cinnamon and buttery flavors.

Wine Choices

A chilled Moscato d’Asti offers a perfect pairing with its light fizz and honeyed notes. For something richer, a Late Harvest Riesling brings stone fruit flavors that complement the cereal’s sweetness. 🍷

Non-Alcoholic Sparkling

Sparkling apple cider adds a festive touch, with its crisp bubbles cleaning your palate. A vanilla cream soda is another fun option that kids and adults alike will love.
