The Dessert My Mom Was Always Asked to Bring!

I’ve shared quite a few of my mom’s famous desserts over the years, the ones she was always asked to bring to parties and family events. One recipe even got requested so much she made it for my sister’s wedding reception!

My personal favorite growing up was always her Carmelitas. (They’re still my all-time favorite bar.) But a close second were her Funfetti bars. They were basically everything-but-the-kitchen-sink dessert bars with a cookie base, marshmallows, M&M’s, chocolate covered pretzels, and sprinkles on top.

These Confetti Bars are inspired by those! They start with a soft white chocolate cookie base and get topped with marshmallows, pastel M&M’s, and sprinkles. I’m so obsessed with them! These are reliable for Spring, but you can easily swap the sprinkle and M&M colors to match any holiday or event.

All the ingredients in this recipe prepped out for straightforward assembly including the brown sugar, flour, vanilla, salt, white chocolate chips, marshmallows, egg, M&Ms, butter, and sprinkles.

Confetti Bars Ingredients

Ingredient	Let’s Chat About It
Butter & brown sugar	Melt the butter and let it cool slightly before mixing so the batter doesn’t turn greasy. Soft, fresh brown sugar gives the bars the best texture.
Egg & vanilla extract	Bring the egg to room temp so it mixes smoothly into the batter.
Flour & salt	mix in gently and stop once the flour disappears to keep the bars soft and tender.
White chocolate chips & marshmallows	Use good-quality white chocolate for the best flavor. Soft, fresh marshmallows make the best Confetti Bars.
Pastel M&M’s & sprinkles	Swap colors to match any holiday or event.

How To Make Confetti Bars

Prep pan: Heat oven to 350°F and line an 8 x 8-inch pan with parchment.
Mix batter: Whisk butter, sugar, egg, vanilla, and salt; fold in dry ingredients.
Bake: Spread in pan and bake until edges are lightly golden and center is set.
Add toppings: Add marshmallows, bake briefly, then finish with remaining mix-ins.
Cool & cut: Let bars set, then slice.

the cook’s Top Tip

Let The Bars Set

Let bars cool completely: Leave parchment overhang so the bars can be lifted out easily, and wait 1 to 2 hours before cutting so the marshmallows don’t pull away from the cookie layer.

Confetti Bars dough pressed into a pan, par baked, then topped with marshmallows, M&Ms, and sprinkles for a quick final bake.

Storage

Because of the marshmallows, these Confetti Bars are best within 1 to 2 days. Once cooled, store the bars in an airtight container at room temperature. If stacking, place parchment or wax paper between layers so the marshmallows don’t stick.
