Why you’ll love this recipe
These cookies are great just for munching, but they also provide a boost of the nutrients a runner (or enthusiastic spectator) needs to keep going. They are like flourless monster cookies with nutritional punch.
Because these aren’t intended as protein bars, but scrumptious treats with protein, I used only a small amount of protein powder in the recipe.
Feel free to double the amount if you don’t mind the slight aftertaste and need more protein. The protein powder can also be left out completely.
These cookies are good to eat before a long run, after a long run, or while standing along a race route, waiting to cheer as your runner passes by. They are also an irresistible, nutritious after school snack.
- In the bowl of an electric mixer, cream together butter and peanut butter. Add granulated and brown sugars. Mix to combine.

My recipe inspiration
I am not a runner. For me, the thrill of endorphins coursing through the body is completely overshadowed by the potential for sweat, bad weather, and leg cramps.
My father was an avid runner, but the running gene skipped a generation. My daughter, Meira, is a runner.
She actually enjoys the challenge. Last weekend, Meira completed a half-marathon for the second time. That’s 13.1 miles!
I think she is amazing. So, I baked her Marathon Cookies.
