These high protein chocolate crispy cakes are a no bake treat made with just three main ingredients, and each one packs around 18 grams of protein. As a dietitian, what I love most is that the protein comes from food, high protein crisps and peanut butter, with no protein powder, which makes them a great option for kids and grown-ups alike.

⭐ Why You'll Love It: A childhood treat made higher in protein, no baking and no powder needed.
Chocolate crispy cakes made with Rice Krispies were one of my favorite treats as a child, and honestly I still love them just as much now. But as an adult and a dietitian, I do try to make most of my snacks a little more balanced where I can. So after making my healthier rice krispie treats, I started experimenting with a high protein version too and these turned out so good.
The trick is swapping the usual rice cereal for high protein crisps. I get mine on amazon and you can choose either soy protein or pea protein based varieties. You still get that crunchy chocolatey texture, but with a lot more protein and without needing to add protein powder.
If you struggle to find soy protein crisps or pea protein crisps where you live, my chocolate quinoa crisps are another great option. They have a very similar crunchy chocolate texture and are made using puffed quinoa instead.
And if you enjoy easy homemade snacks like this, you might also like my soy protein crisp bars or my chocolate peanut butter protein balls for another simple high protein treat.

Why You'll Love These Healthier Chocolate Crispy Cakes
Most high protein treats lean on protein powder. These do not.
- 18.6 grams of protein per cake, all from the high protein crisps and peanut butter. Protein helps you feel full and keeps your energy steady, and it is the part of a snack most of us miss. If you are curious how much you actually need, I break it down in my guide on how much protein you need.
- Family friendly. Children generally should not be consuming protein powders or supplements making these a good option for everyone.
- 2-3 grams of fiber per cake, which is a nice bonus from a chocolate treat.
- No bake and only three main ingredients, so they come together in about ten minutes.
Dietitian note: these are still a treat. At around 275 calories and just under 5 grams of sugar each, they are a more balanced choice than a shop-bought crispy cake, but they are not a low calorie or low sugar food. Enjoy them as part of a balanced day.
What Are Protein Crisps/Crispies?
Despite the name, protein crisps are not like potato chips or “crisps” like Taytos. They are actually much closer to puffed rice cereal or Rice Krispies in texture. They are small crunchy puffed pieces usually made from pea protein or soy protein and are commonly used in homemade protein bars, chocolate snacks, and high protein desserts.
In this recipe, they work as a higher protein alternative to classic rice cereal. You still get that crispy chocolate cake texture, but with much more protein in each serving.
I personally love using them because they make it easy to increase protein without always relying on protein powder. They also blend really well into recipes and do not have a strong flavor.
You can usually find protein crisps online, in health food stores, or on Amazon. I used unflavored pea protein crisps for this recipe, but soy protein crisps work really well too.
Key Ingredients
The complete ingredient list with measurements can be found in the recipe card below.
- Chocolate: This is the main flavor, so use one you would happily eat on its own. Dark chocolate (70% and up) keeps the sugar down and balances the sweetness, while milk chocolate makes them sweeter and more kid-friendly. For dairy-free or vegan, use a dairy-free chocolate. Most dark chocolate already is, but it is worth checking the label.
- High protein crisps: The star of the show, and where the protein comes from. Pea or soy protein crisps both work well. If you are avoiding soy, go for pea. If you need these gluten-free, check the packet, as some brands are certified gluten-free and some are not.
- Smooth peanut butter: This binds everything together, so it needs to be runny. If yours is stiff from the fridge, warm it for fifteen to twenty seconds first so it coats the crisps properly. For a nut-free version, swap in sunflower seed butter or another smooth seed butter.
- Coconut oil (optional): A tablespoon helps the chocolate melt smoothly and set firm. Use refined coconut oil if you would rather not taste any coconut.
- Sea salt (optional): Just a pinch lifts the chocolate and stops the cakes tasting flat.

Recipe Variations
Dark and white swirl: Drizzle a little melted white chocolate over the tops before they set.
Salted crunch: Press a few extra crisps and a little flaky salt on top of each one.
Berry hit: Stir a spoon of crushed freeze-dried raspberries through the mix for a fruity edge.
Equipment
A 12-cup muffin tray plus paper liners, or a silicone muffin tray. I find a silicone tray easiest, as the cakes pop straight out with no sticking.
Expert Tips for Making This Recipe
Measure the crisps by the cup if you can. Different brands weigh differently, so going by cups keeps the ratio right.
Pick a chocolate you would happily eat on its own, since it carries most of the flavor.
Melt the chocolate slowly and gently to avoid it becoming grainy or overheated. If needed, you can add a tablespoon of coconut oil to help loosen the mixture and create a smoother coating.
Storage
Fridge: Store in an airtight container for up to 2 weeks.
Freezer: Freeze in an airtight container or bag for up to 3 months. If eating straight from the freezer let them sit at room temperature for about 5 minutes before eating for the best texture.
FAQs
Yes. They are a nice option for children precisely because the protein comes from food ingredients rather than a protein supplement, and most kids generally do not need huge amounts of protein in the first place. Most children can meet their protein needs quite easily through regular foods like milk, yogurt, eggs, meat, beans, nut butters, and whole grains across the day.
That said, these are still a sweet treat, so I would serve them as a snack rather than a free-for-all. I also like pairing them with something else like fruit or a glass of milk to make the snack a little more balanced and filling.
Yes. Press the mixture into a lined 8x8 inch (20x20 cm) tin instead of muffin cases, chill until set, then slice into squares. You will get a slightly different shape but the same crunch.

Notes
- If needed, add 1–2 teaspoons of coconut oil to help the chocolate melt more smoothly. This is more useful if using dark chocolate, as milk chocolate melts more easily.
- If using a different brand of crispy rice cereal, e.g., Rice Krispies or puffed rice cereal please measure using cups, as cereals can vary quite a bit in weight.
- Press the mixture firmly into each cup so the treats hold their shape.
- Don't rush the melting. Low and slow prevents the chocolate from seizing.
- These are best eaten after a few minutes at room temperature rather than straight from the freezer.
