Spring Confetti Bars start with a white chocolate cookie base and are topped with gooey marshmallows, spring-colored M&M’s, pastel sprinkles, and more white chocolate! These easy dessert bars are sure to please a crowd! For more cookie recipes, try these Lemon Curd Cookies, M&M Cookies, or Bakery-Style Chocolate Chip Cookies. Confetti Bars Growing up, my mom often made these Funfetti bars* for my siblings and me. They were definitely one of our favorite desserts (along with her famous Carmelitas). For her confetti bars, she’d use a chocolate chip cookie base, loads of marshmallows, colorful sprinkles, miniature chocolate chips, and chocolate-covered pretzels. I’m putting a fun twist on her bars by adding springtime M&M’s*, white chocolate chips, and pastel sprinkles. They’re every bit as good as her original confetti bars, but perfectly festive for springtime! These Confetti Bars would make the perfect Easter dessert! *Funfetti and M&Ms have trademarked brand names which we’re using to illustrate the appearance of the recipe. Any similar product will also work. How to make Spring Confetti Bars The step-by-step photos in the collage above this text correlate to the numbered descriptions below. Cream butter and sugars together. Mix until smooth, creamy, and light. Add one egg, one egg yolk, and vanilla extract. Discard the whites of the one egg or use them in this egg wrap recipe. Add dry ingredients. Mix until a thick dough forms and then add in the white chocolate chips. Stir the chips in to finish the Confetti Bars dough. Press dough into a parchment paper-lined 9×13-inch pan. Bake until no longer glossy on top and lightly browned at the edges. (Process photos shown below:) Add marshmallows immediately after removing from the oven, and then return to the oven for 1 and 1/2 minutes. Remove from the oven, sprinkle on M&M’s, white chocolate chips, and finally sprinkles. Let Confetti Bars sit until firm before cutting. QUICK TIP These Spring Confetti Bars are easy to adapt to different holidays, or for everyday use. You can vary the colors in the M&M’s to reflect Memorial Day, Christmas, Thanksgiving or St. Patrick’s Day–or use multi-colored M&Ms for every day! Quick tips If you have a food scale, I highly recommend weighing the flour for an accurate measurement. With too much flour packed into a measuring cup, the cookie base on these confetti bars becomes dense (less cookie-like). No food scale? No problem, just be sure to spoon and level the flour into the measuring cup. Let bars completely cool: Confetti Bars need at least an hour (or two) to cool before cutting them into individual pieces. If you cut too soon, the marshmallow layer tends to separate from the cookie layer. Use fresh marshmallows: The newer and softer the marshmallows, the better the topping on these bars will taste. If you’re concerned about the sweetness of these Spring Confetti Bars, leave off the top layer of white chocolate chips and the sprinkles.

Course Dessert, Snack Cuisine American Keyword confetti bars Prep Time 25 minutes Cook Time 24 minutes Allow bars to set 1 hour Total Time 1 hour 49 minutes Servings 24 bars Calories 206kcal Cost $6.32 Ingredients12 tablespoons (170g) unsalted butter, at room temperature1 cup (205g) white granulated sugar1/2 cup (100g) light brown sugar, lightly packed1 large egg1 large egg yolk2 teaspoons vanilla extract2 cups + 2 tablespoons (300g) white all-purpose flour1/2 teaspoon baking soda1/2 teaspoon fine sea salt1 and 1/4 cups white chocolate chips, divided (1 cup is 160g)3 cups (137g) miniature marshmallows3/4 cup (152g) spring-colored M&M's1-3 tablespoons spring-colored sprinkles (See Note 1) InstructionsPREP: Preheat the oven to 350 degrees F. Grease a 9x13-inch pan with cooking spray and line with parchment paper (I don't recommend lining with foil). These bars are sticky so you do want the parchment paper.WET INGREDIENTS: In a large bowl, combine 12 tablespoons room-temperature butter with the 1 cup white sugar and 1/2 cup light brown sugar in a medium sized bowl. Beat with hand mixer (or in a stand mixer) until light and creamy. Add in the egg, egg yolk, and 2 teaspoons vanilla. Mix until combined.DRY INGREDIENTS: In a separate large bowl, combine the 2 cups + 2 tablespoons white flour, 1/2 teaspoon baking soda, and 1/2 teaspoon salt. Stir. Add wet ingredients to dry ingredients and stir until just combined. With a wooden spoon, stir in 1 cup of white chocolate chips and stir until combined. BAKE: Press the cookie dough into the prepared 9x13-inch pan. Bake the bars for 22-26 minutes or until the top is no longer glossy and edges are ever-so-slightly browned. Remove from the oven and immediately top with the miniature marshmallows. Return to the oven for 1 minute and 30 seconds.FINISHING: Gently press the marshmallows down a little. Sprinkle the remaining 1/4 cup white chocolate chips evenly over the bars. Sprinkle the 3/4 cup M&M's evenly over the bars. Scatter the sprinkles evenly over the bars. SERVE: Let cool completely (these bars take 1-3 hours to really set up) and then cut with a hot, sharp knife (run the knife under hot water, dry, make a slice, repeat). Confetti Bars are best enjoyed within 1-2 days; after that the marshmallows become unpleasant. Video Recipe NotesNote 1: Sprinkles: Use 1 tablespoon nonpareil sprinkles or 2-3 tablespoons jimmies sprinkles.

Oh my gosh do these ever look good! You had me at white chocolate and gooey marshmallows. Thanks for sharing at Simple Supper Tuesday. Reply
I haven’t tried, but because of the marshmallows I don’t think they would do well being frozen and then thawed Reply
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. Reply
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. Reply
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. Reply
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/ Reply
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!! Reply
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 Reply
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
