Recipe preparation for M&M Christmas Cookie Bars

How to Make M&M Christmas Cookie Bars

Preheat Your Oven: Start by preheating your oven to 350°F (175°C). Prepare a 9×13-inch baking dish by greasing it lightly or lining it with parchment paper.

Mix Dry Ingredients: In a medium bowl, whisk together flour, baking soda, and salt until combined. The mixture should look fluffy and light as air.

Cream Butter and Sugars: In a large bowl, cream together softened butter, granulated sugar, and brown sugar until smooth and creamy. You want it light in color—about two minutes of mixing should do the trick.

Add Eggs and Vanilla: Beat in eggs one at a time along with vanilla extract. Make sure everything is well incorporated before moving on—this step is key!

Add Dry Ingredients: Gradually mix in the dry ingredient mixture until just combined; avoid over-mixing as this can make your bars tough!

Add M&M’s: Gently fold in the colorful M&M’s using a spatula until evenly distributed throughout the dough. Feel free to save some for topping!

Bake: Spread the dough evenly into your prepared baking dish. Bake for 25-30 minutes or until golden brown around the edges but still slightly soft in the center—trust me on this!

Let these fabulous M&M Christmas Cookie Bars cool completely before slicing them into squares! Enjoy every last bite and share generously (if you can resist).

Enjoy making these delicious treats!

FAQ

Can I use gluten-free flour for M&M Christmas Cookie Bars?

Absolutely! You can substitute regular flour with a 1: 1 gluten-free flour blend without compromising texture too much. Just ensure it contains xanthan gum or another binding agent for best results.

How do I know when my cookie bars are done baking?

Look for golden edges while the center remains slightly soft; it will continue cooking after removing from the oven. A toothpick inserted should come out mostly clean but may have some moist crumbs clinging.
