Ingredients

• 4 tablespoons unsalted butter
• 10 cups mini marshmallows
• 2 teaspoons ground cinnamon
• 1 teaspoon vanilla extract
• 6 cups Rice Krispies cereal
• 0.5 teaspoons ground cinnamon (optional for garnish)

Directions

Step 1

Grease a 9x13-inch baking dish with butter or cooking spray and set aside.

Step 2

In a large pot, melt the unsalted butter over medium-low heat.

Step 3

Once the butter has melted, add the mini marshmallows to the pot and stir continuously until fully melted and smooth.

Step 4

Stir in the ground cinnamon and vanilla extract until evenly incorporated.

Step 5

Remove the pot from heat and add the Rice Krispies cereal. Gently fold the cereal into the melted marshmallow mixture until fully coated.

Step 6

Transfer the mixture into the prepared baking dish, using a buttered spatula or your hands (greased with a little butter) to press the mixture evenly into the pan.

Step 7

Optional: Lightly sprinkle an additional 1/2 teaspoon of ground cinnamon over the top for extra flavor and visual appeal.

Step 8

Allow the bars to cool at room temperature for about 30 minutes, or until set.
