Valentine’s Day Cookie Bars – this festive cookie bar recipe is absolutely delicious and loaded with chocolate chips and red, white, and pink M&M’s.
Valentine’s Day Cookie Bars
These M&M’s Cookie Bars have become an absolute favorite in our house. I made a Christmas version that has been incredibly popular and I wanted to add a Valentine’s Day version as well. These cookie bars are so easy to make and they bake up so nicely. They are a gorgeous golden brown color and the texture of the mini chocolate chips with the crunchy M&M’s is just delicious! These Valentine’s Day M&M Cookie Bars are perfect for a crowd or a classroom. They can be cut smaller to serve more, or cut larger for a pretty presentation.
How to Make Cookie Bars
- Start by mixing the cookie dough. This is a big batch of cookie dough, so a stand mixer is perfect for the job. You can also use a large bowl and a hand mixer.
- Spread the cookie dough into a 9×13 aluminum cake pan lined with foil and sprayed with non stick cooking spray. The foil allows you to lift the bars out for easy cutting after they cool.
- I also like to add M&M’S and more of the mini chocolate chips to the top before baking for a pretty presentation. Just press they lightly in and enjoy the pretty Valentine colors!
I’ve made versions of these cookie bars for every holiday and they are always extremely popular. Here are some of my top tips based on questions people have asked.
- I initially recommended using a 9×13 glass baking dish for these cookie bars, but have found that they actually bake up more evenly in a 9×13 aluminum cake pan.
- I do not recommend using a disposable pan to bake these bars. The dough is very thick and a disposable pan does not conduct enough heat to cook them properly.
- Sprinkle the extra chocolate chips and M&M’s evenly over the top before baking. If there are too many, they fall to the middle and prevent the cookie bars from baking in the center.
- Do not add extra M&M’S or chocolate chips to the recipe for the same reason as above. The cookie bars won’t be able to bake through.
Can I use parchment paper instead of foil?
Yes, you can line the pan with parchment paper instead of foil. The reason I recommend foil is that it stays in place when transferring the cookie dough to the pan. Parchment paper will slip around quite a bit. Parchment paper may also rip when lifting the heavy cookie bars out of the pan for cutting.

Heart Shaped Cookie Bars
For a festive twist on the cookie bars, try making them heart shaped in a 10 inch heart cake pan. The center will be slightly softer than if using a 9×13 cake pan.
