(Hint: Check out the full list of ingredients and measurements in the recipe card below.)

Directions

I start by preheating my oven to 350°F. Then, I lightly grease a 9×13 casserole dish with nonstick cooking spray and set it aside.
In a large bowl, I combine the yellow cake mix, eggs, vegetable oil, and vanilla extract. I mix it all together until smooth and well-blended.
Once the batter is ready, I fold in the Easter M&M candies and semi-sweet chocolate chips for that extra burst of color and flavor.
Next, I spread the dough evenly into the prepared dish.
I bake the bars for 20-25 minutes or until a toothpick inserted in the center comes out clean. Once baked, I let them cool completely before slicing them into squares and serving.

Servings and Timing

Servings: 12-16 bars (depending on the size of the squares)
Prep Time: 10 minutes
Cook Time: 20-25 minutes
Total Time: 30-35 minutes

Variations

Add-ins: I sometimes switch up the mix-ins depending on what I have at home. You can try using white chocolate chips, peanut butter chips, or even a handful of chopped nuts for some added crunch.
Cake Mix Flavors: If I want a change, I swap out the yellow cake mix for a chocolate or funfetti mix. Each flavor brings its own twist to these cookie bars.
Seasonal Variations: If it’s not Easter, I still love to mix in other candy like regular M&Ms, Reese’s Pieces, or mini chocolate bars. It makes these bars versatile for any time of year.

Storage/Reheating

To store my cake mix cookie bars, I place them in an airtight container at room temperature. They’ll stay fresh for up to 4-5 days, making them great for snacking throughout the week. If I want to keep them for longer, I can store them in the fridge for up to a week. To reheat, I simply pop a square in the microwave for about 10-15 seconds to warm it up, and it’s like they were freshly baked!

FAQs

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

I check for doneness by inserting a toothpick into the center of the bars. If it comes out clean or with a few crumbs, the bars are ready to be taken out of the oven.

Can I use a different type of cake mix for this recipe?

Absolutely! I love experimenting with different cake mix flavors. Chocolate cake mix works wonderfully for a richer treat, and funfetti cake mix adds a festive touch.

Can I freeze the cake mix cookie bars?

Yes, I can freeze them! I wrap the bars tightly in plastic wrap or foil and store them in a freezer-safe bag or container. They’ll last up to 3 months in the freezer. When I’m ready to enjoy them, I just let them thaw at room temperature.

Can I make these cookie bars gluten-free?

To make these bars gluten-free, I’d recommend using a gluten-free yellow cake mix. Be sure to check the other ingredients to make sure they are also gluten-free.

How do I prevent the bars from being too dry?

I make sure not to overbake the cookie bars. I check them at the 20-minute mark, and if they look golden and a toothpick comes out clean, I take them out right away. Overbaking can lead to dry bars, so it’s important to stay vigilant!
