Why You’ll Love This Recipe
- Soft and Chewy Bars: These Christmas cookie bars are like your favorite soft sugar cookie, but in a bar form! The texture is perfect here.
- Simple Decoration: While fancy Christmas cookie decorating can be fun, I think you’ll appreciate the simplicity here. Two colors of icing and some sprinkles are all you need to make these fun and festive.
- Fast and Easy: Bar cookies are the easiest! Mix up the batter, add it to the pan, bake, and decorate. Grinch Cookie Bars are much faster to make than any traditional cookie recipe.
- Flour, Cornstarch, Baking Powder, Salt: These are the dry ingredients for this grinch cookie recipe. The addition of corn starch to cookie recipes keeps them soft.
- Butter: Unsalted butter is preferred when baking, as salted butter can contain varied amounts of salt. We’ll add our own salt to be sure that we aren’t overdoing it.
- Granulated Sugar and Eggs: Two ingredients that are present in just about any good cookie recipe. Leave your eggs on the counter for a bit so that they come to room temperature before mixing them in.
- Vanilla Extract: This is the perfect flavor for Grinch sugar cookies. We will add it to the cookies and to the frosting.
- Green Sprinkles (jimmies) and Food Coloring: to get the pretty green specs inside of the grinch cookies, simple green jimmy sprinkles do the job nicely. Gel food coloring will help us to get the perfect grinch-y shade of green for the frosting.
- Buttercream Frosting: Powdered sugar, more butter, and whole milk start the buttercream frosting party. This stuff is so good, you might have trouble not licking the bowl!

How to Make Grinch Cookie Bars
- Prepare: Preheat the oven to 375°F. Line a 9×13 baking dish with parchment paper and spray the paper with cooking spray. In a large bowl, mix the dry ingredients (flour, baking powder, cornstarch and salt) and set aside.
- Make Cookie Dough: In a large bowl with either an electric hand mixer or a stand mixer, cream the butter with the granulated sugar until light and fluffy. Add the eggs, one at a time, mixing well after each addition. Next add the vanilla and mix until well combined. Add the flour mixture, stirring to incorporate it into the wet mixture. Finally, add the green sprinkles and stir to evenly distribute them.
- Bake: Press the cookie dough into the prepared 9×13 pan, using your hands to be sure that it’s evenly spread. Bake for 25-28 minutes until lightly golden brown. A toothpick inserted into the center of the pan should come out cleanly. Allow to cool completely on a wire rack.
- Make Frosting: Place the butter for the frosting into a large bowl. Using a hand mixer, add in the powdered sugar a little at a time until fully mixed. Next add the salt, vanilla, and milk. Mix until combined. Turn the mixer to medium-high speed, and whip the frosting for 3 minutes until it’s light and fluffy.
- Color Frosting: Separate the icing so that you have about 1/2 cup of frosting in one bowl and the rest in another. Color the smaller amount of frosting red, and color the larger amount using green. Here I used a combination of green and yellow to get the grinch cookies the color that I wanted.
- Frost and Decorate: Use the green frosting to generously ice the top of the cookie bars. Let that set for a bit, then cut the bars into squares. Using a #12 round icing tip, pipe one heart onto each bar.
The Frosting Should Be Fluffy: Make sure you whip the buttercream well to incorporate air into it so that it’s light, fluffy, and amazing.
Use Gel Food Coloring: If all you can find is liquid food coloring, you’ll have a hard time getting these vibrant colors. Gel coloring is a much better option for bright icing colors.
Take a Shortcut: Instead of Piping hearts, use large heart shaped sprinkles instead.
More Flavor: You can add almond, mint, or any other extract to the dough to change the flavor.
Watch out for Powdered Sugar! Don’t add all of the powdered sugar to the bowl at once, you’ll end up creating a Grinch of a snow storm! Add a small amount at a time, and start your mixer at a low speed to incorporate it.
This tutorial makes it super simple! Using a round tip, it’s just two lines in a V shape. If you’re nervous, practice a few on a piece of parchment paper or a plate before piping hearts on your grinch cookies.
You can store leftover cookie bars in an airtight container for up to 5 days at room temperature. Avoid stacking them if you want to keep the decoration nice. Grinch cookie bars can also be stored in the freezer for up to 3 months.
I suggest using jimmy style sprinkles in this recipe because they tend not to bleed. Other types of sprinkles, especially nonpareils (the small, round sprinkles)will likely bleed and turn the cookie bars all green. This is not necessarily a problem, just a different look.
To get this really bright green, I used a few drops of green food coloring with a few less drops of yellow. You should add the gel coloring a little bit at a time to get the right shade. Neon green works well on it’s own, or go a bit less vivid with leaf green.
Don’t let the Grinch steal your Christmas Cookie Bars! You’ll have a hard time giving these away this Christmas, but it will be worth it when you see how much everyone loves the flavor and the decorations on them.
