How to Make M&M Cookie Bars?
1. Preheat the Oven 🕒
Start by preheating your oven to 350°F (177°C). Line a 9×13-inch pan with parchment paper, leaving some edges hanging over the sides. This will help you lift the cookie bars out easily later.
2. Mix the Dry Ingredients 🥣
Grab a bowl and whisk together your flour, cornstarch, baking soda, and salt. Set it aside for now.
3. Combine the Wet Ingredients 🧈
In a separate bowl, whisk the melted butter, brown sugar, and granulated sugar until smooth. Add the eggs and vanilla extract, whisking until fully combined.
4. Mix Everything Together 🍪
Slowly add the dry ingredients into the wet mixture. Use a spatula or a large spoon to mix until the dough is thick and shiny. Fold in your M&Ms and chocolate chips (don’t worry if some don’t stick perfectly).
5. Spread and Bake 🎉
Transfer the dough to your prepared baking pan. Smooth it out evenly, making sure to get into the corners. Bake for about 26–30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out mostly clean with a few moist crumbs.
6. Cool and Slice 🔪
Once done, allow the pan to cool on a wire rack for at least an hour. Use the parchment paper overhang to lift the bars out, and then cut them into squares. Enjoy your warm, gooey goodies!
Tips for Making the Recipe
- Don’t Skip the Parchment Paper: It makes removing the bars from the pan much easier, so don’t skip this step.
- Avoid Overbaking: Start checking the bars around 24 minutes to make sure they don’t dry out.
- Press Extras on Top: For a pretty finish, add some extra M&Ms and chocolate chips to the top of the dough before baking.
- Melted Butter Warm, Not Hot: Cool the butter slightly before mixing, or it could cook the eggs.
How to Serve M&M Cookie Bars?
These cookie bars are incredibly versatile when it comes to serving. Stack them on a plate for casual presentation, or arrange them on a cake stand for a party-ready look. For extra decadence, drizzle them with melted chocolate or serve them with a scoop of vanilla ice cream. Fresh fruit or whipped cream also make elegant additions. Don’t forget to sprinkle a little extra candy on top for added color!
Make Ahead and Storage
Make Ahead:
You can prepare the dough up to three days in advance. Store it in the fridge in an airtight container. Just bring it to room temperature before baking.
Storage Tips:
- Room Temperature: Store leftover bars in an airtight container for up to a week.
- Freezer: Cookie bars freeze wonderfully! Wrap them individually in plastic wrap, then place in a zip-top bag. They’ll stay fresh for up to three months. Thaw at room temperature when ready to enjoy.
