Homemade Cereal
One of the first things that I missed after first going gluten-free and then keto, was cereal. Sometimes, there is nothing more satisfying than a quick and delicious bowl of cereal.
Once I started making homemade dairy-free Keto Granola as well as this super easy 5-Minute Skillet Keto Granola, my cereal cravings were temporarily satisfied!
But as we all know, only having granola as cereal in the morning is just not an option. So I decided to embark on a high protein breakfast cereal that had all the flavour of Reese's Puffs without all the sugar!
Why this Keto Cereal Works
- Healthy - By incorporating healthy high protein and fat wholesome ingredients, this homemade cereal is so healthy (but so delicious!), you won't mind if your kids ask for a second bowl!
- Easy - With a simple melting of some of the ingredients in the microwave, a quick stir and then some time baking in the oven, this keto peanut butter protein cereal comes together quickly with minimal effort.
- Versatile - If you are at all like me, you end up with small containers filled with leftover seeds and nuts. This recipe can be modified to add any variety (or no variety at all!) which makes it a great recipe for odds and ends of nuts and seeds.
- Taste - This high protein breakfast tastes exactly like a bowl of Reese's pieces - what is there not to like???!!
- Texture - Even after adding milk and letting it sit for 5 minutes, this keto peanut butter protein cereal was still nice and crispy. Plus after the keto cereal has all been eaten, you end up with a delicious bowl filled with protein milk!

Ingredients
The list of ingredients below is what I specifically used to make my homemade cereal but feel free to modify or adapt this recipe to whatever quantity of nuts and seeds you have on hand.
- Nuts and Seeds - Walnuts, sliced almonds, pumpkin, sunflower seeds and both shredded and flaked coconut or any combination of nuts can be used
- Protein powder - I use Orgain Pea Protein Powder. For this particular recipe, I used Orgain Chocolate Peanut Butter but vanilla or any other flavour will work.
- Peanut butter - You can use almond butter, tahini or cashew butter
- Sugar-free liquid sweetener - I am in LOVE with ChocZero's Sugar-free Honey and let's face it, there is nothing better than the combination of peanut butter and honey!
- Coconut oil - Filled with healthy fats, coconut oil is used to help add some crispiness to the granola
See the recipe card for quantities.
Instructions
Making homemade cereal is a quick high protein breakfast recipe that the entire family will love!

Add all the nuts and seeds to a bowl and mix them together. Set the bowl to the side.

Add the peanut butter, coconut oil, liquid sweetener and salt to a microwave-safe bowl and microwave for 30 seconds. Stir to incorporate the ingredients.

Pour the peanut butter mixture over the seeds and nuts and stir. Sprinkle the protein powder over the mixture and stir again.

Spread the mixture in a single layer on a parchment-lined baking sheet. Bake at 375 degrees F for 10-15 minutes.

Allow the mixture to cool and crisp before storing in an airtight container for up to 2 weeks.

Hint: If you are using large nuts, such as pecans, walnuts, Brazil nuts or whole almonds, you may want to chop them into smaller pieces or pulse them in a food processor to break them down into smaller pieces.
Substitutions
One of the best things about his keto protein cereal recipe is just how easy you can subsitute ingredients for one's that you already have in your pantry!
- Nuts - if you do not like walnuts, use almonds, pecans or any other type of nut
- Coconut - you can replace the coconut with equal amounts of sliced almonds
- Seeds - You can use any type of seeds or varity of seeds - you can also replace the seeds with more nuts (but I would chop the nuts down slightly) or vice versa and only use seeds and no nuts.
Please realize that the nutritional information will vary if you alter the recipe. This recipe is naturally Vegan but to make it Paleo, use almond or cashew butter instead of peanut butter.
Variations
You can easily convert the flavour of this keto peanut butter protein granola simply by changing out some ingredients
- Chocolate - add chocolate protein powder instead of vanilla
- Deluxe - add some sugar-free chocolate chips or white chocolate chips after the mixture has fully cooled.
- Spices - You can always change the flavour by simply adding some cinnamon, pumpkin pie spice, or cardamom which all make a great addition to this high protein keto granola

Equipment

Storage
Store the cooled keto peanut butter protein cereal in an airtight container for up to 2 weeks or in the freezer for up to 3 months.
Top tip
This keto cereal is best served with milk or yogurt. It is NOT a granola recipe so it is not meant to be chunky.

Can I use a different brand of protein powder?
Yes. You can use pea, egg white or casein protein powder. If you protein powder is not very sweet (or unsweetened), you may want to add 2-4 tablespoons of sweetener, such as erythritol.
Do I have to add protein powder?
No. If you want a higher fat to protein ratio, simply omit the protein powder.
How do I add more protein to my breakfast?
You can add more protein by simply stirring in an additional scoop of portein powder into the cereal before adding your milk. It will add about 10 grams more of protein per serving.
Can I use salted roasted nuts and seeds?
Yes. However, omit the added salt in the recipe.
