Why you’ll love mint hot chocolate cookie bars

These decadent bars are loaded with minty chocolate goodness. Sweet peppermint and rich cocoa powder flavor these chewy bars. Plus they are speckled with marshmallows that melt in your mouth with every bite!

I’ve always loved this flavor combination in a cookie, and now it’s even easier to make as a bar- you can mix all the ingredients in just one bowl and bake them up in one 8 x 8 inch baking dish! So easy to make and even easier to clean up!

Recipe Tips for the best mint hot chocolate cookie bars

For smooth batter, sift the cocoa powder with a mesh strainer to break up any lumps. This will also make for an easier time mixing it into the batter. Use a spoon or spatula to push the pebble pieces through the mesh strainer.

Do not over bake them. The key to a soft and chewy cookie is to pull them out of the oven as soon as they puff up in the center and turn light golden brown around the edges. The same is true for cookie bars. This is not a secret, but it makes a HUGE difference in the texture of your cookie, and I think it also makes them last a little longer too!

Tips for baking with marshmallows

• Freeze the marshmallows! This is the absolute most important tip for baking with marshmallows. Leave them in the freezer for at least two hours to harden. This will help them bake slower so they don’t burn and melt.

• Place a piece of foil over the top of the dish halfway through the bake. This is also crucial to keep the marshmallows from burning.

• If you leave the dish in the oven a little bit too long, the marshmallows will burn and turn translucent, so make sure you remove the pan when the timer goes off, or at least watch it very carefully at the end of the bake. The marshmallows should still look bright white with just a light golden on top when you remove the pan from the oven.

Recipe Variations

You can customize these to your own personal taste buds in a variety of ways. Switch out the semi-sweet chocolate chips for white or dark chocolate chips. Or, if you prefer less mint flavor, skip the peppermint extract and instead add 1/2 cup peppermint chips mixed into the batter with the semi-sweet chocolate chips. This will ensure you get just a hint of the peppermint flavor. Play around with it and don’t forget to have fun!

FAQ

• So why is it called a cookie bar?

  Cookie bars are actually a bar dessert rather than a cookie. Cookies are shaped or dropped onto a pan in individual serving sizes, while cookie bars are baked in a baking dish as one piece and sliced into individual sized pieces. The flavor outcome is very similar, and I find bar cookies to be even faster and easier than cookies!

• Why are my cookie bars dry?

  You either have too much flour in the recipe

  • Your dough will look crumbly and be hard to compact together. Add 1 tablespoon of melted and cooled unsalted butter at a time until until the dough is just able to stick together.

  Or you left the pan in the oven too long

  • Sorry, there is really no way to fix this. The next time you bake this recipe, set a timer and check the bars five minutes early, then you can watch them closely until they are ready - they should be just lightly golden brown around the edges and puffy in the middle.
