Ingredients

5 cups Rice Krispies or crispy rice cereal
2 tablespoons milk (regular or almond milk)
1/2 cup vanilla flavored protein powder
4 tablespoons salted butter

Step 5: Remove the pot from heat and stir in the cereal until the marshmallow mixture fully coats it.
Step 6: Transfer the mixture to the prepared pan and gently press it down. Add sprinkles on top if desired. Avoid pressing too hard to keep the treats light and chewy.

Tips & Variations

Use almond or oat milk for a dairy-free option.
Try chocolate protein powder instead of vanilla for a different flavor.
Add chopped nuts or dried fruit for extra texture and nutrition.
Press mixture lightly to maintain a soft, chewy texture rather than dense bars.

Storage

Store these treats in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. To refresh, let them sit at room temperature before serving or briefly warm in the microwave.

How to Serve

This image shows a stack of six square rice crispy treats on a white plate. Each treat has a light golden beige color with visible puffed rice cereal pieces and white marshmallow bits inside, giving a soft and chewy texture. The top of each treat is decorated with many small, colorful sprinkles in red, blue, yellow, pink, green, orange, and purple, adding a playful and festive look. The treats are neatly cut with clear edges, and in the background, a clear glass of milk with a red and white striped straw sits on a white marbled surface, slightly out of focus.

4 tablespoons salted butter
10.5 ounce bag mini marshmallows
1 teaspoon vanilla extract
Sprinkles (optional)

Instructions

Prepare the pan: Line a 9×9 inch pan with foil or parchment paper and grease with butter or nonstick cooking spray to prevent sticking.

Mix in cereal: Remove the pot from heat and immediately stir in the Rice Krispies cereal, ensuring every piece is thoroughly coated with the marshmallow mixture.
Press into pan: Transfer the mixture into the prepared pan and gently press it down evenly. Avoid pressing too hard to keep the treats light and chewy. Optionally, sprinkle with colorful sprinkles on top.
