Protein Rice Krispies Treats Ingredients
For the Base
- Rice Krispies or crispy rice cereal – This serves as the backbone of your Protein Rice Krispies Treats, giving them that classic crunch. Any brand works!
- Mini marshmallows – These are the magic ingredient for creating that soft, gooey texture; mini marshmallows melt better than large ones.
- Salted butter – Adds a rich flavor that balances the sweetness; you can also use unsalted butter or coconut oil for a dairy-free version.
For the Protein Boost
- Vanilla protein powder – Enriches the treat with a delightful protein boost; substitute it with an unflavored powder for a less sweet option.
- Milk (regular or almond) – Keeps the mixture moist and helps the treats stay soft; feel free to use any type of milk here.
Flavor Enhancement
- Vanilla extract – Adds an extra layer of flavor, although it’s optional; trust me, it makes a world of difference!
For Decoration (Optional)
- Sprinkles – These are purely for fun and visual appeal; don’t hesitate to use colorful sprinkles to enhance the treats!
Step‑by‑Step Instructions for Protein Rice Krispies Treats
Step 1: Prepare the Pan
Start by lining a 9×9 inch baking pan with parchment paper or aluminum foil, ensuring it extends over the edges for easy removal later. Lightly grease the lining with cooking spray or butter to prevent sticking. This step is essential for creating well-shaped Protein Rice Krispies Treats that won’t break apart when sliced.
Step 2: Mix Milk and Protein Powder
In a small bowl, whisk together your choice of milk and vanilla protein powder until fully smooth and well-combined. This mixture adds a creamy base and enhances the overall protein content of your treats. Set this mixture aside while you prepare the next steps, keeping it within arm’s reach for easy incorporation.
Step 3: Melt Butter
In a large pot, place over medium heat and add salted butter. Stir continuously until the butter is completely melted and starts to bubble slightly around the edges. Pay close attention to avoid browning; you want it just melted for a perfect texture in your Protein Rice Krispies Treats.
Step 4: Melt Marshmallows
Once the butter is melted, reduce the heat to low and add the mini marshmallows into the pot. Stir gently until the marshmallows are fully melted and smooth, which should take about 3-5 minutes. Add the vanilla extract and the milk mixture, stirring well to blend all ingredients into a gooey, cohesive mixture.
Step 5: Combine Cereal
Remove the pot from heat and gradually stir in the Rice Krispies or crispy rice cereal. Mix just until all the cereal is evenly coated with the marshmallow mixture, being cautious not to over-mix which can lead to a denser result. You should see the cereal glimmer with the gooey goodness, ensuring your Protein Rice Krispies Treats will be delightfully chewy.
Step 6: Transfer to Pan
Carefully pour the mixture into the prepared baking pan, using a spatula to spread it evenly. Gently press down on the mixture using your hands or a piece of wax paper, but take care not to pack it too tightly to maintain a soft texture. If desired, sprinkle colorful sprinkles on top for added visual appeal, before letting the mixture rest.
Step 7: Allow to Set
Let the Protein Rice Krispies Treats cool at room temperature for 30-60 minutes. This resting time allows them to firm up a bit, making it easier to cut into squares. Once they seem set and no longer warm to the touch, you can proceed to slice them into your desired shapes and sizes.

Expert Tips for Protein Rice Krispies
-
Gentle Pressing: Avoid pressing the mixture too firmly in the pan; this helps maintain the soft, gooey texture we love in Protein Rice Krispies.
-
Monitor Heat: Always melt marshmallows over low heat to ensure they stay fluffy. High heat can cause them to clump or become hard.
-
Fresh Ingredients: Use fresh mini marshmallows for the best gooeyness. Stale marshmallows won’t provide the desired texture.
-
Customize Wisely: While mixing in add-ins like chocolate chips or nuts, remember not to over-mix, as this can lead to dense treats.
-
Proper Storage: Store slices in an airtight container at room temperature for up to a week. Refrigeration can make them hard and less enjoyable.

When you’re ready to eat them, simply let them thaw in the refrigerator overnight or at room temperature for about 30 minutes.
What can I do if my treats are too dense or hard?
If your Protein Rice Krispies Treats turn out denser than expected, it might be due to pressing too hard when packing the mixture into the pan.

If you encounter hard treats, you can microwave them for 5-10 seconds to soften them up a bit—just be sure to monitor closely to prevent melting!

If you’re making these for kids with gluten or dairy allergies, be sure to use gluten-free crispy rice cereal and dairy-free milk. Also, check that your protein powder is allergen-free. As always, it’s best to consult with a healthcare provider regarding specific dietary restrictions.

Definitely! The beauty of these Protein Rice Krispies Treats lies in their customization.
