These Protein Rice Krispie Treats are a fun and tasty twist on the classic snack! Made with crispy rice cereal and a protein-packed twist, they’re perfect for a quick treat.
They’re super easy to whip up, and who doesn’t love a gooey marshmallow treat? I enjoy these after a workout or as a sweet pick-me-up. They’re crunchy, chewy, and oh-so-delicious!
Key Ingredients & Substitutions
Crispy Rice Cereal: This gives the treats their classic crunch. If you’re looking for a healthier alternative, try brown rice cereal or even a puffed quinoa for a unique twist!
Mini Marshmallows: They provide that gooey texture. If you’re avoiding refined sugar, consider using all-natural marshmallows or making a homemade version with gelatin and sweetener.
Protein Powder: Vanilla or chocolate is recommended, but feel free to use your favorite flavor! If you’re vegan, plant-based protein like pea or soy works well. I often use a chocolate flavor for an extra boost of taste.
Chocolate Chips: Semi-sweet or milk chocolate chips are great. For a dairy-free option, look for vegan chocolate chips. You can skip the chocolate topping or use nut butter for a different flavor.
Rainbow Sprinkles: They add a fun touch, but omitted if you’re keeping it simple. For a healthier alternative, use crushed nuts or coconut flakes.
How Do I Get the Perfect Texture for My Treats?
Achieving the right texture is all about the mixing and cooling process. Start by melting the butter and marshmallows gently, avoiding high heat to prevent them from burning.
- Mix in the protein powder while the marshmallows are still warm to ensure a smooth blend.
- Once you add the crispy rice cereal, fold gently to avoid breaking the rice too much. It keeps that light, airy feel!
- When pressing the mixture into the pan, use a lightly greased spatula or wax paper. This prevents sticking and helps achieve that nice flat surface.
- Let the treats cool completely before cutting. This gives them time to set and hold their shape.
Following these steps will help you create delicious, chewy, and crunchy Protein Rice Krispie Treats every time!

Protein Rice Krispie Treats
Ingredients You’ll Need:
- 4 cups crispy rice cereal
- 1 1/2 cups mini marshmallows
- 2 tbsp unsalted butter
- 1/4 cup vanilla or chocolate protein powder (whey or plant-based)
- 1/2 tsp vanilla extract
- 1 cup semi-sweet or milk chocolate chips
- Rainbow sprinkles (for topping)
Time Needed:
This recipe will take about 15 minutes of preparation time, plus an additional 30 minutes to chill in the fridge. In total, you’ll need about 45 minutes, which includes cooling time for the treats to set nicely. Perfect for a quick snack that packs a protein punch!
Step-by-Step Instructions:
1. Prepare the Baking Pan:
Start by lightly greasing or lining an 8×8 inch square baking pan with parchment paper. This will help the treats come out easily when they’re set.
2. Melt the Butter:
In a large pot or saucepan, melt the unsalted butter over low heat. Be patient and keep the heat low to avoid burning the butter.
3. Melt the Marshmallows:
Add the mini marshmallows to the melted butter and stir them continuously until they are fully melted and smooth. This should take a few minutes—make sure they’re completely melted to avoid any lumps!
4. Combine Ingredients:
Once the marshmallows are melted, remove the pot from heat and stir in the vanilla extract and your choice of protein powder. Mix well until everything is combined and smooth.
5. Mix in the Cereal:
Now, add the crispy rice cereal to the marshmallow mixture. Gently fold the cereal into the mixture, ensuring that all the cereal is evenly coated without crushing it too much.
6. Press into the Pan:
Transfer the mixture into the prepared pan, pressing it down evenly with a spatula or a piece of wax paper. Make sure the surface is nice and flat for even cutting later.
7. Melt the Chocolate:
In a microwave-safe bowl, melt the chocolate chips in 20-second increments, stirring after each interval until smooth. Take care not to overheat the chocolate!
8. Top with Chocolate:
Pour the melted chocolate over the pressed cereal mixture in the pan. Use a spatula to spread it evenly across the surface.
9. Add Sprinkles:
Before the chocolate sets, sprinkle the rainbow sprinkles over the top for a burst of color and fun!
10. Cool and Set:
Allow the treats to cool at room temperature or pop them in the fridge for about 30 minutes until the chocolate is firm and set.
11. Cut and Enjoy:
Once everything is set, cut the treats into squares and serve. Store any leftovers in an airtight container for your next snack attack!
Enjoy your protein-packed, colorful, and delicious Rice Krispie Treats!
Can I Use Different Types of Protein Powder?

How Do I Prevent My Marshmallows from Burning?
To avoid burning the marshmallows, always melt them over low heat and stir continuously. This not only helps achieve a smooth consistency but also prevents them from sticking to the bottom and burning.

Yes! To make this recipe vegan, use plant-based butter and vegan marshmallows. Many brands offer great alternatives that work perfectly in this recipe!
How Should I Store Leftover Rice Krispie Treats?
Store any leftovers in an airtight container at room temperature for up to a week. If you need to keep them longer, you can refrigerate them, but they may become a bit firmer. To enjoy them at their best, bring them to room temperature before serving.
