Step‑by‑Step Instructions for Sugar Cookie M&M’s Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grab a 9×13-inch baking pan and lightly grease it with butter or non-stick spray. This ensures that your delightful Sugar Cookie M&M’s Bars will come out easily after baking, setting you up for a stress-free preparation!
Step 2: Mix the Dough
In a large mixing bowl, combine the Betty Crocker sugar cookie mix, softened butter, and egg. Use a hand mixer or your trusty wooden spoon to blend the ingredients thoroughly until a soft and cohesive dough forms, about 2-3 minutes. The mixture should be smooth and slightly sticky, indicative of the delicious bars to come!
Step 3: Fold in the Goodies
Now, gently fold in the white vanilla baking chips and M&M’s, ensuring they are evenly distributed throughout the dough. This step adds a touch of sweetness and color to your Sugar Cookie M&M’s Bars. Make sure to mix until you see bits of chocolate and vibrant candy nestled in the dough, ready to bring joy to each bite!
Step 4: Spread into the Pan
Transfer the cookie dough mixture into your prepared baking pan. Using a spatula or the back of a spoon, evenly spread the dough across the bottom of the pan, smoothing down the surface. This will create an even baking layer, ensuring all pieces turn out equally delicious when you indulge in these festive treats!
Step 5: Bake to Perfection
Place the baking pan in your preheated oven and bake for 20-25 minutes. Keep an eye on the edges as they should turn a lovely golden brown. To check for doneness, insert a toothpick into the center; it should come out clean or with a few moist crumbs. This indicates that your Sugar Cookie M&M’s Bars are perfectly baked!
Step 6: Cool and Slice
Once baked, remove the pan from the oven and allow the bars to cool in the pan for about 10-15 minutes. This cooling period helps the bars set before slicing. After they have cooled enough to handle, cut them into squares or rectangles, showcasing the colorful M&M’s that make these bars a festive favorite!

How to Store and Freeze Sugar Cookie M&M’s Bars
Airtight Container: Store the bars in an airtight container at room temperature for up to 7 days, ensuring they stay soft and chewy for all your holiday snacking needs.
Refrigeration: For extended freshness, refrigerate the bars where they can last up to 2 weeks. Just be sure to seal them tightly to prevent drying out.
Freezing: You can freeze Sugar Cookie M&M’s Bars for up to 3 months. Wrap them individually in plastic wrap, then place in a freezer-safe container to preserve their delightful flavor.
Thawing: To enjoy frozen bars, simply transfer them to the fridge overnight to thaw. You can also warm them slightly in the microwave for that fresh-baked taste!
Make Ahead Options
These Sugar Cookie M&M’s Bars are perfect for meal prep, allowing you to enjoy delightful treats with less effort during your busy days! You can prepare the dough up to 24 hours in advance; simply combine the sugar cookie mix, softened butter, and egg, then fold in the white vanilla baking chips and M&M’s. Cover the mixing bowl tightly and refrigerate until you’re ready to bake. To maintain quality, ensure the dough is well-wrapped to prevent drying out. When you’re set to serve these festive bars, spread the dough into the baking pan and bake as instructed. You’ll have fresh, delicious treats with minimal effort that everyone will love!

Sugar Cookie M&M’s Bars Recipe FAQs
What is the best way to choose M&M’s for my bars?
When selecting M&M’s, I recommend using seasonal varieties to enhance the festive spirit! Look for bright, vibrant colors that will beautifully contrast with the golden dough. Ensure the M&M’s are not damaged; avoid any with dark spots, as they may not look appealing in your finished bars.
How should I store my Sugar Cookie M&M’s Bars?
Store your bars in an airtight container at room temperature for up to 7 days—this will maintain their coveted soft and chewy texture! If you need them to last longer, pop them in the fridge where they can stay fresh for up to 2 weeks. Just remember to seal them tightly to prevent them from drying out.
Can I freeze these Sugar Cookie M&M’s Bars?
Absolutely! To freeze your bars, wrap each one individually in plastic wrap. Place them in a freezer-safe container, and they’ll stay delicious for up to 3 months. When you’re ready to indulge, transfer the desired amount to the fridge overnight to thaw. For that freshly baked taste, you can warm them briefly in the microwave right before enjoying!
What if my bars turn out too dry or crumbly?
If your Sugar Cookie M&M’s Bars are too dry, it may be due to overbaking. Keep an eye on them during the last few minutes of baking—remove the bars as soon as the edges are golden and a toothpick comes out clean or with a few moist crumbs. Also, make sure your butter is softened—this moisture is key to achieving that perfect chewy texture!
Are there any dietary considerations for these bars?
If you have concerns about allergies, keep in mind that M&M’s contain milk and may also have traces of nuts. For a lighter version, you can substitute the egg with 1/4 cup applesauce. If you’re baking for pets, remember that chocolate is toxic to them, so be sure to keep these away from furry friends.
