I baked a batch for my friends to enjoy one morning while we decided our arena was too muddy and slippery to risk running our horses. We were sad. Cookies totally make up for being cold and caked in mud though. After I shared these I had requests all around for my recipe.
Monster Cookies are just what is needed on a cold and dreary day when you can’t go outside to play.
Visions of (Monster) Cookies
Something about the phrase “Monster Cookie” always conjures up an image of the Cookie Monster from sesame street. Am I the only one who has ever thought that these are the cookies Cookie Monster should be eating? Anyone else? They are his namesake after all.
Even though I add extra sugar and candy to this recipe ( it is a cookie, not a health food) I don’t add butter. Why? Because I forgot to add it once and everyone raved about my monster cookies! Now it is part of my recipe. Maybe you could call them “healthier” – I don’t think anything with that much sugar can be considered healthy though . You may burn a few calories by stirring in all the oatmeal .

Be prepared to stir in the oatmeal by hand. You will appreciate all the work your mixer can do.
Be prepared to shuttle a number of cookies in and out of the oven – or use a giant sheet pan if you have one and it fits in your oven. The batch size and cook time are dependent on your definition of a large scoop. I use an ice cream scoop – if you have something else you like better, use it.
Time to get your hands dirty and make some cookies.

Notes
If you want chewy cookies, They do not look golden brown when taken out of the oven. It always takes a bit of faith on my part to pull the. Out of the oven at that point. if you want crunchy cookies wait until the tops are golden brown
