Monster Cookies are a favorite for my family. They're chewy, peanut buttery, chocolatey, and easy to make. They're made with oats instead of flour!
Today I bring you another recipe redo. I first posted my recipe for Monster Cookies way back when I was first starting my blog.
In fact, it was exactly the third recipe I ever posted. Back when I had no idea what I was doing, and still using my old point-and-shoot camera to take my photos (not that there is anything wrong with point-and-shoot, but mine in particular was really terrible).
Definitely make these monster cookies. They are truly one of my family's favorites. I make them most often for hiking or camping trips or picnics. They disappear very quickly.
You can even make them for friends or family who follow a gluten-free diet, as they are made with only oats - no flour at all. (Just make sure that your friends can tolerate oats. Not everyone who needs to follow a gluten-free diet can).
How to make Monster Cookies:
Making monster cookies is very easy. In fact, as long as you're comfortable getting a bit of an arm workout, no mixer is required. Simply stir together the eggs, sugar, vanilla, salt, peanut butter, and softened butter. Then stir in the oats, baking powder, and chocolate.
As soon as the dough is mixed, you can portion it onto your baking sheets. No chilling is required for these cookies either.
Monster Cookies Ingredients:
This is one time when I will recommend using a more processed ingredient. The peanut butter you use in these cookies should be the smooth, processed type (think Kraft, JIF or Skippy).
While I love the natural kind that is nothing but peanuts, it won't give you a good result in these monster cookies.
- Large eggs
- Light brown sugar
- Granulated sugar
- Vanilla extract
- Smooth peanut butter: Make sure to use the processed kind that doesn't separate - you will get better results than with natural peanut butter
- Unsalted butter: Use a dairy-free butter alternative to make these cookies dairy-free
- M&M's: Skip these and add extra dairy-free chocolate chips to make these cookies dairy-free
- Chocolate chips: Use dairy-free chocolate chips to make these cookies dairy-free)
- Baking powder
- Rolled oats NOT instant or steel-cut oats: They might also be called old-fashioned oats.
