Sugar cookies have always been a favorite treat for those who love a simple, sweet, and buttery dessert. However, rolling and cutting out sugar cookie dough can be time-consuming. That is where M&M Sugar Cookie Bars come in. These bars take the classic sugar cookie recipe and transform it into an easy, no-fuss dessert that does not require individual shaping or decorating. Instead, you simply press the dough into a pan, bake, and cut it into squares for a delicious and colorful treat.
These bars are soft, chewy, and packed with M&Ms, making them a fantastic option for anyone who enjoys a bit of crunch and chocolate in their desserts. The golden edges and melt-in-your-mouth texture make them irresistible. Whether you are baking for a holiday, a party, or just craving something sweet, this recipe delivers every time.
One of the best things about this recipe is how versatile it is. You can switch out the M&Ms for different flavors or colors depending on the occasion. For example, pastel M&Ms work perfectly for Easter, red and green for Christmas, and classic colors for a year-round treat. You can even mix in chocolate chips, sprinkles, or chopped nuts to add extra flavor and texture.
Because these bars are so easy to make, they are perfect for beginners and experienced bakers alike. There are no complicated steps or special equipment needed, just basic pantry ingredients that come together to create a buttery, chewy dessert with a delightful crunch from the M&Ms.
Why You’ll Love This Recipe
There are many reasons why M&M Sugar Cookie Bars deserve a place in your baking rotation. They are fun, colorful, and packed with the classic flavors of a sugar cookie, all in an easy-to-make bar format. Here are a few reasons why you will love this recipe.
1. No Rolling or Cutting Dough
Traditional sugar cookies require rolling out the dough and using cookie cutters, which can be time-consuming and messy. With this recipe, you simply press the dough into a pan and bake. This makes the entire process much faster and easier, perfect for when you want a sweet treat without extra effort.
2. Soft, Chewy, and Buttery Texture
These bars are thick, soft, and slightly chewy in the center, with a lightly golden crust on the edges. The butter and sugar create a rich, melt-in-your-mouth texture, while the M&Ms add a slight crunch that enhances every bite.
3. Perfect for Any Occasion
These bars are great for any event or celebration. Whether you are making them for:
- Birthday parties
- Bake sales
- Holidays like Christmas, Easter, or Halloween
- School lunches or snacks
- Potlucks and gatherings
They are always a hit. You can customize the M&Ms to match the colors of the season or special occasion.
4. Simple and Foolproof Recipe
Even if you are a beginner baker, this recipe is straightforward and easy to follow. The dough comes together in just a few minutes, and because you bake it all in one pan, there is less risk of overbaking or burning individual cookies.
5. Customizable to Your Taste
This recipe is highly adaptable, allowing you to experiment with different flavors and textures. Here are some fun variations you can try:
- Mix in chocolate chips or white chocolate chips for an extra layer of sweetness.
- Add sprinkles for a fun and festive touch.
- Use peanut butter or crispy M&Ms for a different crunch.
- Drizzle melted chocolate or caramel over the top for a more decadent version.
6. Stores Well and Stays Fresh
Unlike traditional sugar cookies that can dry out quickly, these bars stay soft and fresh for several days when stored in an airtight container. This makes them a great make-ahead dessert that you can enjoy throughout the week.
7. Kid-Friendly and Fun to Make
Kids love anything with M&Ms, and these bars are no exception. They can help mix the dough, press it into the pan, and decorate with extra M&Ms before baking. It is a great recipe for family baking days or introducing kids to the joy of homemade treats.
Now that you know why this recipe is a must-try, let’s explore the health benefits of the ingredients used in these bars.
Health Benefits
While M&M Sugar Cookie Bars are a sweet indulgence, they contain several ingredients that offer nutritional benefits when consumed in moderation. Here are some of the key benefits of the ingredients used in this recipe.
1. Butter: A Natural Source of Healthy Fats
Butter provides richness and flavor to baked goods while also supplying healthy fats and fat-soluble vitamins like A, D, E, and K. Using real butter instead of margarine ensures a more natural and wholesome treat.
2. Eggs: A Great Source of Protein and Vitamins
Eggs are packed with protein, healthy fats, and essential vitamins such as vitamin B12 and choline, which support brain function and energy levels. They also help bind the ingredients together, creating a smooth and uniform dough.
3. Flour: Provides Fiber and Energy
All-purpose flour supplies carbohydrates for energy, and using whole wheat flour as a substitute can increase fiber content and make these bars a bit more nutritious.
4. M&Ms: A Fun Source of Antioxidants from Cocoa
While M&Ms are mostly sugar, they do contain real cocoa, which provides antioxidants that support heart health. Choosing dark chocolate M&Ms can boost these benefits slightly.
5. Sugar: A Quick Source of Energy
Sugar provides a quick energy boost, making these bars a great option for an occasional sweet treat. To reduce sugar, you can substitute part of the white sugar with coconut sugar or honey.
Now that we have covered the benefits of the ingredients, let’s look at the preparation time, servings, and nutritional breakdown.

Ingredients List
- ½ cup butter, softened (1 stick)
- ¾ cup white sugar
- 1 large egg
- 1½ teaspoons vanilla extract
- 1¾ cups all-purpose flour (7.4 ounces)
- ½ teaspoon baking powder
- ¼ teaspoon salt
- ¼ cup M&Ms, plus extra for topping
Step-By-Step Cooking Instructions
1: Gather Your Ingredients
For a 8×8-inch pan of M&M Sugar Cookie Bars, you’ll need:
Dry Ingredients:
- 1¾ cups all-purpose flour (7.4 ounces)
- ½ teaspoon baking powder
- ¼ teaspoon salt
Wet Ingredients:
- ½ cup butter (1 stick), softened
- ¾ cup white sugar
- 1 large egg
- 1½ teaspoons vanilla extract
Mix-Ins:
- ¼ cup M&Ms (plus extra for topping)
🔸 Tip: Want an extra festive touch? Use seasonal M&Ms (pastel for Easter, red and green for Christmas, etc.).
2: Prepare Your Baking Pan
- Preheat your oven to 350°F (175°C).
- Grease an 8×8-inch baking pan with butter or non-stick spray.
- Line the pan with parchment paper for easy removal.
🔸 Tip: If you want thinner bars, use a 9×9-inch pan and reduce the baking time by 2-3 minutes.
3: Cream the Butter and Sugar
- In a large mixing bowl, beat the softened butter and sugar together using a hand mixer (or stand mixer) until the mixture is light and fluffy (about 2 minutes).
- Add the egg and vanilla extract, then continue mixing until smooth.
🔸 Tip: Make sure your butter is softened but not melted for the best texture.
4: Mix in the Dry Ingredients
- In a separate bowl, whisk together the flour, baking powder, and salt.
- Slowly add the dry ingredients into the wet mixture, stirring until just combined.
- Avoid overmixing, as this can make the bars denser rather than soft and chewy.
🔸 Tip: If the dough feels too dry, add 1-2 teaspoons of milk to help it come together.
5: Add the M&Ms
- Gently fold in the M&Ms using a spatula, distributing them evenly.
- For a more decorative look, press a few extra M&Ms on top of the dough before baking.
🔸 Tip: Want extra crunch? Add chopped nuts or white chocolate chips along with the M&Ms!
6: Press the Dough into the Pan
- Transfer the dough to the prepared baking pan.
- Press it evenly into the pan using your hands or a spatula.
- Smooth the top so the bars bake evenly.
🔸 Tip: Lightly grease your hands with butter or spray them with non-stick spray to prevent the dough from sticking while pressing it down!
7: Bake to Perfection
- Place the pan in the preheated oven and bake for 18-20 minutes, or until the edges are lightly golden.
- Test for doneness by inserting a toothpick in the center—if it comes out clean or with a few moist crumbs, it’s ready.
- Let the bars cool in the pan for 10-15 minutes before transferring to a wire rack to cool completely.
🔸 Tip: If you prefer soft, gooey bars, bake for closer to 18 minutes. For firmer, slightly crispy bars, bake for 20-22 minutes.
8: Cut and Serve
- Once completely cooled, lift the bars out using the parchment paper.
- Cut into squares or rectangles, depending on your preference.
- Enjoy immediately or store for later!
🔸 Tip: Want extra sweetness? Drizzle with melted white chocolate or top with buttercream frosting!

Common Mistakes to Avoid
Making M&M Sugar Cookie Bars is easy, but a few common mistakes can lead to dry, overly dense, or unevenly baked bars. Here’s what to avoid:
1. Overmixing the Dough
Overmixing can cause the cookie bars to become dense and tough instead of soft and chewy.
✔ Solution: Mix just until the flour is incorporated—no need to keep stirring once combined.
2. Using Cold Butter
Cold butter doesn’t cream well with sugar, leading to uneven texture and dense bars.
✔ Solution: Use softened butter (let it sit at room temperature for 30 minutes or microwave for 10 seconds).
3. Measuring Flour Incorrectly
Too much flour makes the bars dry and crumbly, while too little makes them thin and greasy.
✔ Solution: Use the spoon and level method—scoop flour into the measuring cup and level it with a knife.
4. Baking Too Long or at the Wrong Temperature
Overbaking results in dry, hard cookie bars, while underbaking makes them doughy in the center.
✔ Solution: Bake at 350°F for 18-22 minutes and check with a toothpick—it should come out with a few moist crumbs, not wet batter.
5. Not Lining the Pan
Skipping parchment paper can make removing the bars difficult.
✔ Solution: Line the baking pan with parchment paper or grease it well for easy removal.
6. Adding M&Ms Too Early
Mixing M&Ms into the dough before baking can cause them to sink.
✔ Solution: Reserve some M&Ms and press them onto the top halfway through baking for a better look.
7. Cutting Too Soon
If cut while warm, the bars may crumble or lose shape.
✔ Solution: Let them cool completely before slicing for clean, even squares.
Pro Tips for the Best M&M Sugar Cookie Bars
1. Make Them Extra Chewy
✔ Slightly underbake (about 18 minutes) for soft, chewy bars. They will continue setting as they cool.
2. Use Different M&Ms for Variety
✔ Swap regular M&Ms for:
- Peanut Butter M&Ms for extra richness.
- Mini M&Ms for better distribution.
- Seasonal M&Ms (red and green for Christmas, pastels for Easter).
3. Enhance the Flavor with Add-Ins
✔ Try mixing in:
- ½ teaspoon almond extract for a bakery-style flavor.
- ½ cup white or dark chocolate chips for extra sweetness.
- A sprinkle of sea salt on top to balance the sweetness.
4. Make Them into Blondies
✔ Swap white sugar for ½ cup brown sugar + ¼ cup white sugar to create a caramel-like, blondie texture.
5. Double the Recipe for More Servings
✔ Use a 9×13-inch pan and double all ingredients for a bigger batch. Bake for 25-30 minutes.
6. Store Properly for Freshness
✔ Store bars in an airtight container at room temperature for up to 4 days or freeze for up to 3 months.
7. Serve with Ice Cream for a Next-Level Dessert
✔ Warm a bar in the microwave for 10-15 seconds and serve with vanilla ice cream for a decadent treat.
Frequently Asked Questions (FAQs)
1. Can I Use Salted Butter Instead of Unsalted?
✔ Yes, but reduce the added salt to just a pinch to balance the flavors.
2. What If I Don’t Have Baking Powder?
✔ Substitute ¼ teaspoon baking soda + ½ teaspoon vinegar to help with leavening.
3. Can I Make These Bars Gluten-Free?
✔ Yes! Use a 1:1 gluten-free baking flour for best results.
4. Can I Make These Without Eggs?
✔ Yes! Substitute:
- ¼ cup unsweetened applesauce
- ¼ cup mashed banana
- 1 tablespoon ground flaxseed + 3 tablespoons water (flax egg)
5. How Do I Prevent the Bars from Being Too Hard?
✔ Don’t overbake—remove from the oven when the edges are golden but the center is slightly soft.
6. Can I Freeze M&M Sugar Cookie Bars?
✔ Yes! Wrap individual bars in plastic wrap and store in a freezer-safe bag for up to 3 months.
7. Can I Make These Bars Dairy-Free?
✔ Use vegan butter and dairy-free chocolate candies.
