If you want a cute, Pinterest-worthy holiday treat without doing a ton of work, these Santa Nutter Butter Cookie Bars are it. They look adorable enough to impress anyone, but they’re honestly so easy that the kids can help without turning the kitchen into a full-blown Christmas disaster. Simple, sweet, and totally doable, which is pretty much the exact kind of holiday magic I need as a busy mom of three.😅

How To Decorate Santa Nutter Butters

To decorate the Nutter Butter’s to look like Santas, I used this post from Taste of Home as a reference but here’s how I did mine:

  1. Melt white chocolate (I love using Ghirardelli melting wafers . They melt smoothly and set up with a nice, glossy finish).
  2. Dip one end of each cookie into melted chocolate and allow the excess to drip off. Then place the cookies on a wire rack and sprinkle red sugar on the top part (for Santa’s hat). Then press a white chocolate chip as the pom pom for the hat.
  3. Next, dip the other end of each cookie into melted chocolate for the beard (leave the center of the cookie uncovered for the body). Then, finally, attach two mini chocolate chips for the eyes and a red mini M&M for the nose.

Ingredient Notes

(For the full recipe, scroll down to the recipe card below)

Santa Nutter Butter Cookie Bars - 6
  • All-purpose flour: As always, it’s essential to make sure you’re using the spoon and level method to measure your flour when baking (you can also use a kitchen scale to weigh your ingredients).
  • Peanut butter : Make sure to use a peanut butter like Skippy or Jif for the right consistency. Don’t use a natural peanut butter.
  • Unsalted butter: Melt the butter, then let it cool slightly before mixing it in. This helps keep the eggs from cooking and gives your cookie bars the perfect, chewy thickness.
  • Eggs + egg yolk: The extra egg yolk adds additional richness and helps to make these cookie bars super soft. Make sure both your egg and egg yolk are at room temperature.
  • Nutter Butters: You’ll use 5 Nutter Butters to fold into the dough (I like to place them in a plastic zip-top baggie and chop them into small pieces), then use the rest to decorate into Santas to top the bars with!

Expert Tips

  • Prepare your pan: I like to spray my 9×13 baking pan with nonstick spray, then line it with parchment paper, so when you spread the batter onto the parchment paper, it’s stable in the pan and doesn’t slide around everywhere.
  • Use the proper peanut butter: Make sure to use a peanut butter like Skippy or Jif for the right consistency. Don’t use a natural peanut butter. The creamy texture of the peanut butter helps to keep these cookie bars soft and chewy.
  • Properly measure the flour: As with any baking recipe, make sure to spoon the flour into your measuring cup and use the back of a knife to level off the top. Do not scoop the flour out of the container/bag with your measuring cup because you could end up with 50% more than you need. See this baking tip video for an easy tutorial.
  • Allow the melted butter to cool: Allow the melted butter mixture to cool before adding it to the eggs (or it will cook the eggs and we don’t want that!).
  • Do not over-mix: Gently fold the dry ingredients into the wet. You want to mix just until a soft dough forms, and there are no streaks of flour left. Over-mixing can lead to tough coffee bars.
  • Don’t over-bake: Make sure to pull the bars from the oven when the edges look lightly golden but the center still looks a tiny bit underdone. They’ll finish setting as they cool in the warm pan.
  • For the cleanest cuts: If you want really nice, clean cuts, pop the bars into the refrigerator to chill for a bit. Then run your knife under hot water, wipe dry, slice, and repeat. It makes every bar look bakery-perfect.

Variations / Substitutions

Storage / Freezing

  • Store these cookie bars in a sealed container at room temperature for up to 5 days. Try to store the bars in a single layer to avoid smudging or flattening the decorated Santas on top.
  • Freeze (undecorated bars): For best results, freeze the bars without the decorated Santa Nutter Butters on top. Bake and cool completely, then wrap the whole slab tightly in plastic wrap and a layer of foil. Freeze for up to 3 months. Thaw overnight in the fridge, then add the decorated Santa Nutter Butters on top when ready to eat.
  • Freeze (decorated bars): Place the bars on a sheet pan and freeze uncovered for 1–2 hours to set the decorations. Once frozen solid, wrap each bar individually and store in a freezer-safe bag. Thaw in the refrigerator overnight or at room temperature for 1-2 hours. Just be aware that the decorated Santas may soften slightly as they thaw.

Of course! Feel free to totally skip decorating the Santas (I just think it adds a cute touch) and place plain Nutter Butters on top of the baked cookie bars. Or you can skip the extra Nutter Butters completely and just include the chopped ones inside the cookie dough.

Can I bake these bars in a smaller pan?

Yes. A 9×9-inch pan will make thicker bars. Add 5–10 extra minutes of bake time.

How do I keep the Santa decorations from smearing?

I recommend storing/transporting the bars in a single layer so the faces stay neat.
