Cereal is one of the most nostalgic and comforting breakfast foods, but let’s be honest—it’s often loaded with sugar and lacking in protein. While protein cereals are gaining popularity in stores, many of them either taste like cardboard or come with a hefty price tag. That’s why making your own protein cereal at home is a game-changer.

This recipe is a high-protein take on a classic favorite: Cinnamon Toast Crunch. It delivers that satisfying crunch, the perfect blend of cinnamon sweetness, and the protein boost you need to fuel your day—all without unnecessary additives or excessive sugar.

Why Make Your Own Protein Cereal?

With the growing popularity of high-protein diets, many people are looking for ways to increase their daily intake without relying solely on shakes and bars. This homemade protein cereal is an excellent way to incorporate more protein into your diet while still enjoying a delicious, crunchy breakfast.

1. Control Over Ingredients

Store-bought cereals often contain preservatives, artificial flavors, and excess sugar. When making your own, you have complete control over what goes into it—whether you prefer natural sweeteners, different types of flour, or a specific protein powder.

2. Balanced Macros for a Satisfying Breakfast

A typical serving of this protein cereal provides 10 grams of protein with only 155 calories, making it a well-balanced option for those looking to stay full longer. Pair it with milk or yogurt, and you’ve got a powerhouse breakfast with even more protein.

3. Stays Crunchy in Milk

One of the biggest disappointments in cereal is when it turns into a soggy mess after a few minutes in milk. This recipe has been tested and perfected to maintain its crunch, making every bite just as enjoyable as the first.

Ingredients – The Muscle-Building Mix

Main Dough:

120g (1 cup) All-Purpose Flour
56g (1/2 cup) Almond Flour (can substitute with more all-purpose flour)
45g (1.5 scoops) Cinnamon or Vanilla Protein Powder
50g Granulated Sugar Substitute (or regular sugar)
2 tsp Cinnamon
1/4 tsp Salt
5-6 Tbsp Milk of Choice (adjust based on protein powder type)

Cinnamon Sugar Topping:

1 tsp Cinnamon
40g Granulated Sugar Substitute (or regular sugar)

Directions – Your Roadmap to Crunchy Goodness

Mix the Dry Ingredients: In a large bowl, whisk together all-purpose flour, almond flour, protein powder, sugar substitute, cinnamon, and salt.
Form the Dough: Add milk gradually, one tablespoon at a time, mixing until a firm dough forms. (Whey protein may need 5 tbsp; a whey/casein blend may need 6 tbsp.)
Chill for Success: Refrigerate the dough for 30-60 minutes to make it easier to work with.
Preheat & Prep: Heat oven to 350°F (175°C). Divide the dough in half and place each portion between two sheets of parchment paper.
Roll It Out: Sprinkle extra flour on top and roll the dough as thin as possible. Thinner dough leads to crunchier cereal.
Flavor Boost: Lightly spray the dough with cooking spray, then sprinkle the cinnamon sugar mixture evenly over the top. Press gently to help it stick.
Cut Into Cereal Shapes: Use a pizza cutter to slice the dough into small squares. No need to separate them before baking.
Bake to Perfection: Place the parchment paper onto a baking sheet and bake for 16-18 minutes (16 minutes for whey protein, 18 minutes for a blend).
Cool & Crunch: Allow the cereal to cool for 30 minutes—this is when it hardens and becomes crispy. If it’s not crunchy enough, let it sit for another hour.
Break & Enjoy: Once fully cooled, break apart the pieces and store them in an airtight container for up to two weeks.

Customizing Your Protein Cereal

One of the best things about this recipe is how versatile it is. Whether you want to adjust the flavor, change the flour base, or experiment with different toppings, there are plenty of ways to make this cereal your own.

1. Protein Powder Choices

The type of protein powder you use can affect both the texture and taste of the cereal.

Whey Protein: Works well but may require slightly less liquid.
Whey/Casein Blend: Provides a great texture and holds up well in baking.
Plant-Based Protein: While not tested extensively, it may work with some adjustments.

2. Sweetener Options

If you’re avoiding artificial sweeteners, you can use coconut sugar, honey, or maple syrup instead of a sugar substitute. Just note that this will slightly increase the calorie count.

3. Flour Substitutions

Oat Flour: A good gluten-free alternative, though it may change the crunchiness.
More Almond Flour: If you want a higher fat and protein content, you can increase the amount of almond flour, but expect a slightly softer texture.

4. Flavor Variations

While this recipe mimics the cinnamon-sugar goodness of Cinnamon Toast Crunch, you can easily switch up the flavors:

Chocolate Protein Cereal: Add unsweetened cocoa powder to the dry mix.
Vanilla Almond Crunch: Use vanilla protein powder and almond extract for a nutty twist.
Pumpkin Spice Cereal: Replace cinnamon with pumpkin spice for a fall-inspired version.

Storage and Shelf Life

Homemade cereal doesn’t contain the preservatives found in store-bought options, but it still has a decent shelf life when stored properly.

At Room Temperature: Store your cereal in an airtight container in a cool, dry place for up to two weeks.
In the Refrigerator: While not necessary, refrigerating it can help keep it fresh longer.
Freezing Option: If you make a large batch, you can freeze it in an airtight container for up to a month. Just let it sit at room temperature before eating.

Frequently Asked Questions

1. Can I Make This Without Protein Powder?

Yes, but the protein content will be lower. If you omit the protein powder, you may need to adjust the amount of flour and milk slightly to achieve the right dough consistency.

2. Will This Work With Dairy-Free or Plant-Based Protein?

Plant-based protein powders tend to absorb more liquid, so you may need to experiment with the amount of milk. Some plant-based proteins also have a grittier texture, which could affect the crunchiness of the cereal.

3. How Do I Ensure the Cereal Stays Crunchy?

The key to a crunchy texture is rolling the dough as thin as possible and baking it until the edges turn golden brown. If your cereal isn’t crispy enough after cooling, let it sit out for another hour or bake it for an additional 1-2 minutes.

4. What’s the Best Way to Eat This Protein Cereal?

This cereal is delicious on its own as a crunchy snack, but it’s even better when served with milk or yogurt. You can also sprinkle it over smoothie bowls or mix it with nuts for a high-protein trail mix.

5. Can I Double the Recipe?

Absolutely! If you want to make a larger batch, simply double all the ingredients. Just be sure to roll out the dough in separate portions to maintain even baking.

6. Is This Recipe Kid-Friendly?

Yes! While it’s designed for those looking to increase protein intake, kids will love the sweet cinnamon flavor. You can use regular sugar instead of a sugar substitute if preferred.
