Monster cookie mix in a jar is a great way to shortcut making some of our absolute favorite cookies. Make up several jars to keep in your pantry or give them as gifts to teachers, neighbors, family and friends.

I couldn’t do a series on making homemade mixes in a jar and not include our favorite cookies. We LOVE our big batch monster cookie recipe.
Of course, it is WAY to large to fit into a reasonable sized jar. So, we had to scale it down a bit. Luckily if 32 cookies isn’t enough, you can just make more than one jar!
We just love the chewy texture the peanut butter and oatmeal give to Monster cookies. You can use holiday M&Ms to make them even more festive if you want.
Assembling the jars is super simple. I like to stir the baking powder, baking soda, and salt into the sugar in order to reduce the risk of getting a clump in the actual cookies later.
We tried filling up the jars a couple of different ways. Obviously, the order you put the ingredients in the jar doesn’t really affect what the cookies taste like.
However, we decided it looked best if you broke the oatmeal up into two sections. Otherwise the oatmeal layer is very thick and the jar isn’t quite as visually pleasing.


If you are giving the jars as gifts, you can use cute ribbons or even add some festive fabric over the lid. If you are keeping them for your pantry, you are done.

Just make sure to include the baking instructions. We like to write them on little brown cardboard tags so that they are cute and easy.
There are so many reasons that making your own mixes is a great idea. Whether you are looking for a hostess gift or a little something to pass out at Christmas time, there is no bad time for cookies.
Filling The Jars
- Using wide mouth jars makes both loading them and emptying them a little bit easier.
- Canning funnels usually only cost a couple of dollars and they can make getting everything in the jar so much easier.
- The jar will be really full, so you may have to pack the layers down a bit as you go.

Monster Cookie Mix In A Jar
Ingredients

- ½ cup granulated sugar

- Pour in the contents of the jar and stir until the mixture is uniform. It should form a thick dough.
- Scoop a rounded Tablespoon of dough onto a cookie. Continue scooping the dough, leaving 2 inches between each mound of dough until the sheet is full. Bake for 9-11 minutes.
