You don’t need any special equipment for this recipe, but I would recommend using a stand mixer. This dough gets pretty thick, and once you add in the candy mix-ins, it would be VERY hard to stir everything together by hand. Here are some of my favorite kitchen tools I used for this recipe:

Tools

  • 9×13 baking casserole dish – I have this dish and I adore it because it comes with a lid that fits it. No more fooling with aluminum foil or plastic wrap! Plus it keeps the smells of your dish inside the dish and not in your refrigerator as foil and plastic wrap do!
  • Oven Mitts – This is a heavy and hot dish! Make sure you have good oven mitts to protect your hands!
  • Parchment Paper Sheets – This is parchment paper that’s already cut for you! And it is the size of a half-baking sheet pan, which is absolutely perfect!
  • Mixing Bowls – These nesting mixing bowls are fabulous. They store easily and the lids come in so, so handy! I adore them and I love the colors!
  • Spatula Set – This is the greatest set ever. Not only does it have several handy spatulas, it has a few tiny ones too, to help you get every single scrape out of jars and containers!
  • Glass Mixing Bowls – This is a nesting set of glass bowls. I find I can’t have enough glass bowls in my kitchen!

Machinery

Kitchen Aid Stand Mixer – I have used this machine for 15 years. It’s never once failed me and it looks like it’s still brand new. It is worth every single penny I paid for it!

Baking Instructions

Step 1

Spray/Grease a glass 9×13 baking dish and set aside. If you want to really ensure easy removal, you can always line the baking dish with parchment paper.

Step 2

Butter, peanut butter, brown sugar and white sugar in a stainless steel stand mixer bowl

Using a stand mixer, mix your wet ingredients (the butter, peanut butter, sugar, and brown sugar) until they are all incorporated and look light and fluffy.

Step 3

Step 4

Everything Christmas Peanut Butter Oatmeal Bars with flour mixed in

Add in the flour, baking soda, salt, and oats and mix until combined.

Step 5

Everything Christmas Peanut Butter Oatmeal Bars dough with decorative add ins included like m&ms, peanut butter chips, Christmas sprinkles and chocolate chips

Add in the chocolate chips, peanut butter chips, M&Ms (Save a few to sprinkle on top of the bars) and half the sprinkles (save the other half for the top of the bars) and stir until just mixed.

Step 6

Press dough into the baking dish and press down until flat and even in the dish. Sprinkle the remaining M&Ms and sprinkles on the top of the bars.

Step 7

Bake peanut butter oatmeal bars at 350* for 20-25 minutes until the sides look cooked like a cookie. You don’t want to overcook, we want chewy bars that have a ton of gooey flavor.

Step 8

Servings

The serving size for these bars depends on how you cut them! You can have 12 larger size bars or 24 much smaller bite-sized bars. I usually go with the smaller-size bars. They are a delicious treat but they are decadent with all those delicious candy additions!

Storage

You can store these bars in an airtight container at room temperature for up to 5 days. But they usually don’t last nearly that long at our house, as they are eaten up quickly!

Frequently Asked Questions

Can I change what candies and chips are in the mix?

For sure! The important thing is to just maintain the ratio of mix-ins. This recipe calls for 3 cups of mix-ins total, plus 4 Tablespoons of sprinkles. Feel free to substitute the mix-ins to your preference! Adding some nuts would be a great option!

Can I substitute in natural peanut butter?

Sure! Use whatever kind of peanut butter you prefer! If the dough is too dry with natural peanut butter, add in another egg or a few tablespoons of milk to loosen it back up a bit.

Could I make this recipe vegan?

You’d need a substitute for the eggs and butter and then use vegan chocolate as well.

Can I use crunchy peanut butter?

Go for it! It would be a great addition and I bet it would be even more awesome than the original!
