Aren’t these Spring confetti bars so cute?! And perfect for Spring and/or Easter?
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!
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.
- 1/2 cup butter at room temperature
- 1/2 cup white sugar
- 1/4 cup + 1 tablespoon brown sugar
- 1 large egg at room temperature
- 1 teaspoon vanilla extract
- 1 and 1/2 cups white flour
- 1/2 teaspoon baking soda
- 1 teaspoon baking powder
- 1/2 teaspoon cornstarch
- 1/4 teaspoon salt
- 1 and 1/4 cups white chocolate chips separated
- 3 cups miniature marshmallows
- 3/4 cup Spring M&Ms
- 3 tablespoons sprinkles Spring colored
-
Preheat the oven to 350 degrees F.
-
Combine the room temperature butter with the white and brown sugar in a medium sized bowl.
-
Mix the butter and sugars together with hand beaters or in a stand mixer until creamy and fluffy. Mix in the egg and vanilla and beat until just incorporated.
-
In a separate bowl, combine the flour, baking soda, baking powder, cornstarch, and salt. Stir together and slowly add the dry ingredients to the wet ingredients.
-
Mix until combined.
-
With a wooden spoon, stir in one cup of the white chocolate chips. Press the cookie dough into a 9 x 13 pan that has been sprayed with nonstick spray.
-
Bake the cookie dough for 17-22 minutes or until the edges are lightly browned.
-
Remove and immediately top with the miniature marshmallows and M&M's. Return to the oven for 1-2 minutes or until the marshmallows become puffy.
-
Remove and sprinkle the remaining 1/4 cup white chocolate chips and sprinkles over the bars.
-
Let cool completely and then cut with a wet knife.

Wow! They are beautiful. Thanks for sharing.
Thank you!
hey guys one quick question are these good>.
These look amazing!! Do they freeze well? thanks
I haven’t tried, but because of the marshmallows I don’t think they would do well being frozen and then thawed
did you use salted or unsalted butter? Thanks. Can’t wait to make these!
You can use either one. If you use salted just omit the added salt.
can you refrigerate these immediately after baking?
I wouldn’t recommend doing that
These are so adorable and look sooo yummy! Do you think these would be okay on Easter if I made them today (Friday)?
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.
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.
I like them best the day of!
So adorable! Love all the pastels!
Thank you Eden! 🙂
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
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.
These were so delicious and adorable! I made them last year for Easter and shared them on my blog this week! Thanks for the recipe! http://www.happilyfrazzled.com/super-sweet-easter-treats/
Oh this makes my day! So fun to see a review on your blog! Thank you Carrie 🙂
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!
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!!
They are delicious!! Super easy and fun! Love the colors and they are just so yummy!
So happy you enjoyed them! Thank you so much for the comment 🙂
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
So happy this was a hit! 🙂 Thanks for the comment!
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?
The dough sits great overnight! Cover it tightly and you’ll be good to go 🙂 Enjoy!
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.
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!
