There is so much holiday cheer in these Christmas peanut butter cookie bars! Filled with creamy peanut butter, oats, peanut butter chips, m&m's and festive Christmas sprinkles.
Today is day 6 of the '12 days of Christmas Cookies' here on Modern Crumb!
We're switching gears a bit and making a really festive, fun holiday cookie today. These Christmas peanut butter bars are a really close recipe to my chewy oatmeal peanut butter chocolate chip bars.
You know what a fan I am of cookie bars, because of just how easy they are to make. In the pan they go, bake, done.
The peanut butter chips really add an extra peanut butter oomph. I eat way too many whenever I make these!
Since these are holiday cookies, these peanut butter bars get red and green m&m's and a generous amount of Christmas sprinkles. This is a definitely a kid approved recipe! What kid doesn't love sprinkles?!
Christmas Peanut Butter Cookie Bars Tips
Before you start baking, check out my tips for success! I can't be the only person who thinks peanut butter cookies can be tricky. Here's a few of my best suggestions.
Use close to room temperature ingredients. This will ensure a smooth, creamy batter and even baking.
Line the baking pan with parchment paper. Using parchment paper makes it easy to pull the cookie bars out of the pan. No sticking, easy clean up.
Press the cooking dough down in to the baking pan firmly. It should be a nice even layer to all sides.
For extra festive cheer, prior to baking you can sprinkle a few of the m&m's and sprinkles on top of the cookie dough, press them in slightly.
These cookie bars are slightly under baked, so that they can be extra chewy. If you like a bit more bite, add a few extra minutes. In general, a cookie bar will be chewier than a traditional cookie.
Here are a few ingredients that make these cookies just so special! Don't skip these.
- peanut butter - for this recipe, I use a creamy peanut butter
- oats - traditional oats, not the instant oats
- m&m's - the basic milk chocolate m&m's, just the green and red ones or you can buy an actual bag of holiday m&m's and those only have green and red
- peanut butter chips - I love the extra peanut butter taste from these, these are just like chocolate chips but instead of chocolate they are peanut butter
- Christmas sprinkles - any Christmas themed sprinkles will work, I use roughly two tablespoons
Here are the answers to some of your most frequently asked questions.
I use an 8x8 square metal baking pan.
I haven't tested it with chunky peanut butter, I wouldn't be able to say what the outcome would be.
You may not have baked them long enough, oven temperatures and heat can vary, put them back in the oven for a few more minutes.
This recipe is for a more chewy cookie bar, but you can check the temperature if you want to be sure, the guideline is a cookie should have an internal temperature of 185 degrees.
