Old Fashioned Monster Cookies!

I wish I had some awesome story about how my grandma made them in 1942, but yeah. It was just me tinkering away in my kitchen and putting together what I envisioned an old fashioned cookie would be like.

Old Fashioned Monster Cookies!

Seems like that today cookies are all ooey gooey and soft and loft-house style and not the crispy flakey cookies I remember as a kid.

I cannot believe I am old enough to have eaten old-fashioned food.  Old enough to want to eat old-fashioned food.

It makes sense though.  My favorite TV show is Murder, She Wrote.

Old Fashioned Monster Cookies!

Recipe based on Oatmeal Cranberry Cookies.

Tips for Success:

These cookies spread out considerably so I would press them flat(er) as you set them on the baking sheet.

If you want a higher dough to chip ratio (less chips, more cookie dough), cut the chocolate chips out and decrease peanut butter to 1/2 cup.

Make sure you cream the shortening and sugars until fluffy.  I have used both the whisk attachment and paddle and both seem to work well.

I love making these cookies into “giant” cookies, about 6-inches across.  They hold up very well and kids are absolutely giddy at the idea of the huge cookie.

These cookies are best served right out of the oven with a tall glass of cool milk! #da

  1. I have so many nostalgic childhood memories of monster cookies.. these look awesome and I wish I had a couple to indulge in right now!

  2. This is a different version of monster cookie than I’ve been using for years. My recipe has a touch of corn syrup and no flour – only oats so they are nice and chewy! We love them and make them every Christmas!

  3. I made these today using butter instead of shortening. They turned out thin, crispy, and soooo good! I used Resee’s Pieces instead of peanut butter chips and added 1/2 cup of crushed pretzels because I didn’t have any salt. Awesome recipe and super helpful baking blog…thank you!!
