Instructions

1
Preheat your oven to 350°F (175°C).
2
Grease a 9x13 inch baking dish with cooking spray.
3
Place the cubed butter evenly on the bottom of the dish.
4
Drizzle the vanilla extract over the butter.
5
Pour the entire bag of marshmallows over the butter in an even layer.
6
Top the marshmallows with 8 cups of the crispy rice cereal.
7
Bake for 15-20 minutes, until the marshmallows are puffed and melted around the edges.
8
Carefully remove the dish from the oven. Grease a spatula with cooking spray.
9
Stir the mixture together directly in the pan, bringing the melted ingredients from the bottom up to coat the cereal.
10
Add the remaining 1 cup of crispy rice cereal and stir to combine.
11
Once everything is mixed, use the greased spatula to press the mixture evenly and firmly into the pan.
12
Let the treats cool completely before cutting into squares and serving.

Tips & Notes

Pro tips

Spread cereal evenly in the dish and press gently after baking to ensure uniform texture and adhesion.
Cube the butter before adding so it melts evenly across the marshmallows and cereal without hot spots.
Watch the final 2 minutes closely—the top will go from light golden to burned quickly once marshmallows caramelize.
Let cool in the pan for 5 minutes before cutting; this helps the treats set and prevents them from falling apart.

Substitutions

Large marshmallows → mini marshmallows (reduce bake time by 1–2 minutes; watch for uneven melting)
Crispy rice cereal → Cocoa Krispies or Frosted Flakes (changes flavor; bake time remains the same)
Butter → coconut oil (use 6 tbsp; flavor will be subtly different but texture works well)

Storage & make-ahead

Store in an airtight container at room temperature for up to 3 days; reheat gently in a 275°F oven for 2–3 minutes if desired.

Common Questions

Can you bake Rice Krispies treats instead of using the stovetop method?

Yes. This recipe bakes them in a single dish instead of melting on the stovetop, resulting in a toastier, more caramelized texture with less stirring required.
