Easy Sugar Cookie Confetti Bars

Aren’t these Spring confetti bars so fun?! And perfect for Spring and Easter-time?

Growing up my mom often made these confetti bars for my siblings and me. They were definitely one of the favorite desserts (along with these carmelitas).

She would use a chocolate chip cookie base, loads of marshmallows, colorful sprinkles, miniature chocolate chips, and chocolate covered pretzels.

They are the 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 wouldn’t let us to eat them because they were ONLY for confetti bars.

Which was fine by us; as long as she kept good on her word to make them!

These confetti bars are similar, but a little bit different. The base is a white chocolate chip cookie dough that is baked for about 17-22 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 for 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

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

    Reply

    • 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.

  35. 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.

  37. How well do these keep? Do they stick together due to the marshmallow? Can they be individually wrapped or will they stick to the plastic? Sorry for so many questions. I’m a bus driver and like to make my kiddos holiday treats.
    Thank you

    Reply

    • You sound like the best bus driver ever! They unfortunately don’t keep too well, kind of past there prime even by the end of the second day unfortunately 🙁 They do wrap pretty well though and don’t stick too bad to plastic because of the M&M’s and sprinkles on top kind of push down the marshmallows.

  39. These are so cute! Is the cookie bar supposed to be doughy or more of a crisp cookie?

    So fun for kids to help decorate!

    Reply

    • We prefer it more doughy, but bake longer for a more well done cookie. They shouldn’t be crisp 🙂 Yes so fun for kids to get involved!!

  41. I made this in a pie dish as a second birthday cake for brother yesterday. Everyone loved it. I loved the chewy cookie texture. I will surely be hitting the gym hard this week. Lol

  42. These look amazing and perfect for Easter!! Would be so easy to make the dough the night before and pop in the oven the next day! Does anyone know if the dough sits well overnight?

    Reply

  43. I couldn’t get the dough to stretch into a 9×13 pan :/ just wasnt enough to stretch it without there being gaps. it didnt look like the video lol. used an 8×8, hope its okay.

    Reply

    • I hope you were able to get it to work out ok in the 8 x 8 pan 🙂 It does stretch very thin in the 9 x 13 pan!

  44. These weren’t a love for me. The brownie base was kind of bland and most of the marshmallow separated from the brownie when I went to cut them up.

    Reply

  45. I noticed you said that the base would bake for 13-15 minutes but the recipe says 17-22 minutes so which time is correct?
