Delicious Confetti Cookie Bars with Spring M&M's and lots of gooey marshmallows!Aren’t these so cute?! And perfect for Spring slash Easter?

I don’t know if you can tell, but there are little bunny sprinkles on these bars. I just about died when I saw them! So cute!

And the Easter or Spring M&M’s are my favorite. I love those pretty pastel colors and the occasional little M&M bunny or chick printed on the candies.Delicious Confetti Cookie Bars with Spring M&M's and lots of gooey marshmallows!Growing up my mom always made confetti bars for my siblings and me. They were definitely my favorite dessert.

She would use a chocolate chip cookie base, loads of marshmallows, colorful sprinkles, miniature chocolate chips, and chocolate covered pretzels. PS. Mom are you impressed I remember all those ingredients?!

Yeah they were the richest & best dessert bars! We’d always get excited when my mom would buy miniature chocolate chips or when chocolate covered pretzels would go on sell. Because that meant lots of confetti bars! My mom would hide the miniature chocolate chips and forbid us to eat them. They were only for these confetti bars.

Which was fine by us. As long as she kept good on her word to make these!

Easy Sugar Cookie Confetti Bars

These confetti bars are similar, but a bit different. The base is a white chocolate chip cookie dough that is baked for about 13-15 minutes. Then marshmallows, white chocolate chips, and M&M’s are thrown on top and these bars get baked for another 2-3 minutes. Everything gets all sorts of gooey and delicious. And then comes the time for sprinkles!

I used white chocolate to make these a lighter and more Spring-like dessert. You can definitely change out the white chocolate for milk, dark, or semi-sweet chocolate. Just make sure to change the chocolate chips in the base and in what is sprinkled on top.

      I haven’t tried, but because of the marshmallows I don’t think they would do well being frozen and then thawed

  10. Heather says

    These are so adorable and look sooo yummy! Do you think these would be okay on Easter if I made them today (Friday)?

    • chelseamessyapron says

      I believe they are the best the day of because of the marshmallows. The day after is okay but I wouldn’t stretch them too much longer than that.

  11. says

    These are so cute! I’m making them as an Easter treat for the kids. I make white chocolate chip bars all the time- the confetti addition will be fun! With the marshmallows on top, are they best made and served on the same day or are they fine to to make a day ahead? Thanks.
