Once you try this keto breakfast cereal recipe, you’ll never go store-bought again! It comes together using common keto pantry staples, it’s sweet, and it has ALL the crunch. Low carb cereal never tasted so good! (And if you don’t have time to make a homemade recipe, I’ll show you where to find the best options to order, too.) It’s fun to make low carb versions of classic breakfasts (pancakes or bagels, anyone?), but sometimes you need a meal with a little more crunch. This keto friendly cereal fills that craving with lots of sweet flavor and crispy texture. The best keto cereal needs the best ingredients, so I’m relying on Wholesome Yum Erythritol as the sweetener. It’s the perfect choice for recipes that need sweet taste and a crispy bite, with zero net carbs.

Can You Eat Cereal On Keto?

Conventional, store-bought cereal on keto is a no-go, since every one of them uses some form of white flour, sugar, or artificial ingredients. But there’s good news: It’s super easy to make low carb breakfast cereal at home, with real ingredients and safe sugar substitutes.

Low Carb Cereal Ingredients

This section explains how to choose the best ingredients for keto friendly cereal, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

Almond butter – We use this as a binder for the low carb cereal dough, and believe it or not, it also adds crunch when baked. You can use any nut butter you like, as long as it’s sugar-free and only made with keto friendly nuts.Wholesome Yum Erythritol – Adds sweet flavor and helps the keto breakfast cereal stay crunchy. This is one of the rare cases where I don’t recommend allulose-based sweeteners. Erythritol helps the cereal keep its crunch. Use code CEREAL for 10% off your first order of erythritol here. 🙂Vanilla extract – Enhances the sweet flavor in this keto diet cereal.Egg white – Also helps the healthy low carb cereal recipe hold together. Make sure it’s at room temperature.Whey protein powder – Protein powder turns this cereal into keto protein cereal! Use an unflavored powder with no fake ingredients. Check the carb count because some are less pure and the carbs can add up fast in this recipe. I recommend this zero carb whey protein powder.Natural powdered food coloring – Makes this keto approved cereal rainbow-colored! Omit if you prefer a more natural look. If you use a different brand, the amount you need may vary, so just add what you need to get the color you want. Keep in mind that most natural colors fade when baked, but this one keeps its color pretty well.

How To Make Keto Cereal

This section shows how to make keto breakfast cereal with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.

Cream wet ingredients and sweetener. Beat the almond butter, sweetener, vanilla, and egg white in a large bowl.Add protein. Beat in the protein powder.

Color. Beat in the food coloring (you can also knead it in if the dough is too stiff). Knead the dough until smooth, then chill for 1 hour.Form cereal. Roll the dough into small balls with your fingers and place on a parchment lined baking sheet.

FYI: Even after chilling, this dough is sticky. It can help to cover your hands in oil or water to reduce sticking. If the dough starts to warm up and get runny, you may need to chill it again.

Bake. It’s done when the top feels firm and starts to harden. Cool completely to fully crisp up.

Tips For The Best Keto Cereal

This homemade keto cereal recipe is so easy to prepare, but keep a few tips in mind to make sure it bakes up perfectly:

Use room temperature ingredients. Otherwise, they won’t blend uniformly.Use zero carb protein powder. I mentioned this above, but can’t emphasize this enough. The carbs in this keto cereal can be quite high if your protein powder is not zero carb, so stick to this one.Don’t skimp on chilling time. Warm dough will be too sticky to work with.Don’t overcook! Cereal won’t fully harden until it cools, but if you bake it too long, it will be rock hard after cooling. Bake just until firm, but not completely solid in the oven.

Low Carb Cereal Variations

Squares – Instead of rolling into balls, roll the dough into a thin sheet (1/8 inch thick) between two oiled pieces of parchment paper and cut into small squares. This method seems easier, but in my experience it’s actually kind of more work because the dough is very sticky. Feel free to try it though.Chocolate – For “keto cocoa puffs” type cereal, replace 2-3 tablespoons of the whey protein powder with cocoa powder.Peanut butter – Almond butter makes a more neutral tasting cereal, but if you love peanut butter, swap the almond butter with peanut butter instead.Granola – If that’s your cereal preference, use my keto granola recipe.

Storage Instructions

Store low carb cold cereal in an airtight container for up to 2 weeks — no refrigeration needed.
