These Pastel M&M Easter Cookie Bars are the kind of treat that disappears fast at spring gatherings. They’re soft, chewy, and packed with pockets of chocolate in every bite. The pastel candies make them instantly festive without any extra decorating.
Best of all, they’re easy to mix in one bowl and bake in a single pan. If you’re looking for a no-fuss dessert that still looks special, this recipe delivers.
Pastel M&M Easter Cookie Bars
Ingredients
- 1 cup 2 sticks unsalted butter, melted and slightly cooled
- 1 cup packed light brown sugar
- 1/2 cup granulated sugar
- 2 large eggs at room temperature
- 2 teaspoons pure vanilla extract
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon fine salt
- 1 cup pastel M&M candies plus a handful for topping
- 1 cup semi-sweet or milk chocolate chips optional, but great for extra chocolate
- Flaky sea salt for finishing (optional)
Instructions
- Prep the pan. Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the long sides. Lightly grease the parchment. Preheat your oven to 350°F (175°C).
- Melt the butter. Melt the butter and let it cool for 5–7 minutes until just warm, not hot. This helps achieve a glossy, chewy crumb instead of a greasy one.
- Whisk the sugars and butter. In a large bowl, whisk the melted butter with brown sugar and granulated sugar until smooth and slightly thick, about 30–45 seconds.
- Add eggs and vanilla. Whisk in the eggs and vanilla until the mixture looks creamy and well combined. Don’t overmix.
- Combine dry ingredients. In a separate bowl, whisk flour, baking soda, baking powder, and salt. Add this to the wet ingredients and fold with a spatula just until no dry streaks remain.
- Fold in the chocolate. Gently stir in 3/4 cup of the pastel M&Ms and the chocolate chips. Reserve the remaining M&Ms for the top.
- Spread in the pan. Scrape the dough into the prepared pan. Use an offset spatula or the back of a spoon to spread it into an even layer. Press the reserved M&Ms on top for a colorful finish.
- Bake. Bake for 20–25 minutes, until the edges are set and lightly golden and the center no longer looks wet. A toothpick should come out with a few moist crumbs, not wet batter.
- Cool and finish. Let the bars cool in the pan on a rack for at least 30–45 minutes. If you like a sweet-salty contrast, sprinkle a pinch of flaky sea salt on top while warm.
- Slice and serve. Use the parchment overhang to lift the slab out. Slice into squares or rectangles with a sharp knife. Wipe the blade between cuts for clean edges.
What Makes This Special
These cookie bars are everything people love about chocolate chip cookies but in a thicker, bakery-style square. The edges turn golden and slightly crisp while the center stays gooey and soft. Pastel M&Ms add color, crunch, and creamy chocolate all in one swipe.
You can make them ahead, slice them cleanly, and bring a platter to any brunch or egg hunt. They’re also easy to customize with different mix-ins or gluten-free flour blends.

Storage Instructions
- Room temperature: Store in an airtight container for 3–4 days. Slip in a slice of bread to help keep them soft.
- Refrigerator: Keep up to 1 week. Let bars come to room temp before serving for best texture.
- Freezer: Wrap individual bars in plastic and place in a freezer bag. Freeze up to 2 months. Thaw at room temperature or warm for 10–15 seconds in the microwave.
Health Benefits
These cookie bars are a treat, but there are a few smart choices baked in. Using melted butter allows for even mixing with less need for heavy creaming, and it helps portion control since the bars slice neatly. Dark or semi-sweet chocolate can add flavanols, which are antioxidants, compared with white chocolate.
You can also add fiber by swapping 1/2 cup of the all-purpose flour for white whole wheat flour without changing the texture much. Consider adding 1/3 cup chopped nuts for healthy fats and a little protein if there are no allergy concerns.
Common Mistakes to Avoid
- Overbaking. Pull the bars when the center is just set. They continue to cook as they cool, which keeps them soft.
- Hot butter + eggs. If the butter is too hot, it can scramble the eggs and lead to greasy bars. Let it cool slightly first.
- Packing the flour. Scooping straight from the bag can compact the flour. Spoon it into the cup and level it off for accuracy.
- Skipping the parchment. Lining the pan makes removal and slicing cleaner. It also prevents sticking.
- Mixing the candies too aggressively. Gentle folding prevents cracked candies and streaked color.
Alternatives
- Gluten-free: Use a 1:1 gluten-free baking flour blend with xanthan gum. Check that your candies are GF-friendly.
- Dairy-free: Swap in plant-based butter sticks and use dairy-free chocolate chips. Many candy-coated chocolates contain milk, so choose a dairy-free brand if needed.
- Flavor twists: Add 1 teaspoon almond extract with the vanilla, or stir in 1/2 cup shredded coconut or crushed mini pretzels for sweet-salty crunch.
- Less sweet: Reduce granulated sugar to 1/3 cup and use dark chocolate chips to balance sweetness.
- Mix-in swap: Use pastel sprinkles, chopped mini eggs, or white chocolate chips for a different look and flavor.
FAQ
Can I make these in an 8×8 or 9×9 pan?
Yes, but the bars will be thicker and need more time. Start checking around 28–32 minutes and look for set edges and a barely set center.
Do I need to chill the dough?
No.
This recipe is designed for immediate baking. Chilling isn’t required, though a 20-minute chill can make slicing even cleaner.
Why did my bars turn out crumbly?
You may have added too much flour or overbaked. Measure flour carefully and pull them when the center still looks soft.
They firm up as they cool.
Can I double the recipe?
Yes. Bake in two 9×13 pans or a rimmed half sheet pan. For a sheet pan, begin checking at 18–20 minutes since the layer may be thinner.
How do I get neat slices?
Cool completely, then use a long, sharp knife.
Wipe the blade between cuts and use a gentle sawing motion to avoid smashing the edges.
What if I don’t have M&Ms?
Use any candy-coated chocolates, chopped chocolate bars, or a mix of chocolate chips and pastel sprinkles for a similar look.
Can I make them less rich?
Swap 1/2 cup of flour with oats pulsed into coarse meal and use 3/4 cup chocolate chips instead of a full cup. The texture stays soft with a slightly lighter feel.
How do I keep the M&Ms from sinking?
Reserve a handful to press onto the top right before baking. This keeps the candies visible and evenly distributed.
Are these safe to ship?
Yes.
Wrap bars tightly in plastic, then in foil, and pack in a snug tin. They ship well for a few days without drying out.
Can I add frosting?
Sure. A thin layer of vanilla or cream cheese frosting is delicious.
Let the bars cool fully first, then add sprinkles or extra candies on top.
