Protein Cereal Bars

We’re back with another cheap and simple protein bar recipe! These 5 ingredient Protein Cereal Bars only take around 5 minutes to make and can be made a million different ways with your favorite cereal.

To make this, all you’ll need is a large enough stovetop pan to fit your entire recipe and something to press your mix into.

Start your cereal bars by turning your burner on low heat. Add right into your pan 1 tablespoon of butter, 8 tablespoons of nut butter, and 5 tablespoons of a sweetener like brown rice syrup, honey, or even a sugar free syrup if that would work better for your macros.

I’ll include the nutritional information for multiple variations down below in the recipe card.

Mix those ingredients together as they heat up until everything is smooth and combined. Don’t let them sit long enough to burn!

Allergic to peanut butter? For a nut butter alternative, SunButter both works and tastes great! It’s a bit pricier than peanut butter but not too bad, I think I paid $6.

Once those ingredients are combined, add in 2 scoops of your favorite good tasting protein powder. I’m using a vanilla one today but any flavor will work as long as it compliments the nut butter.

Mix your powder in until “smooth“. It shouldn’t look too wet and it shouldn’t be too dry or your protein cereal bars will likely fall apart. If it does appear to be too dry you can add a little sugar free syrup in.

Last, mix in 1-2 cups of your favorite cereal. This can literally be anything, even granola! The most important part to this step is to make sure that all of your cereal is coated by the time you’re done mixing it.

Cereal Macros

For the overall macros you can add the cereal in separately which will give you flexibility (however I do give multiple options/examples below). The reason I suggest doing this is that the type of cereal you’re using can completely change them. These can be a pretty balanced bar, one higher in carbs, or one higher in fat depending on what you use.

Also remember that since some cereal is denser than others, you’ll have to eyeball this step. I usually use around 100 grams depending on the cereal. It’s better to start out by not putting enough than to put too much so start out on the low end.

Onto the next step! Take out something to put your mix into it, optionally line it, and dump your mix in. Press and pack down your protein cereal bars mix evenly across whatever you’re using, I find using my hands makes this step easier. 

Put that into the fridge or freezer for a few or until everything hardens up then cut your bars up. In the end they should look like this…

A couple tips for these?

Protein Cereal Bars

  1. If you have questions regarding cooking protein powder we have a video and article that goes over it if you’d like to check that out here.
  2. Melt some sugar free chocolate or nut butter and drizzle or pipe it over the top!
  3. If you did it right, once they harden in the fridge they’ll be good to go and won’t fall apart.
