How to Make St Patrick’s Mint Marshmallow Confetti Bars

Preheat your oven to 350°F (175°C) and prepare a baking dish by greasing it lightly or lining it with parchment paper for easy removal of the bars later.
Cream together the unsalted butter, granulated sugar, and brown sugar in a large bowl until the mixture is light and fluffy, about 3-5 minutes. This will create a wonderful base!
Incorporate the large eggs one at a time, mixing well after each addition, followed by the aromatic splash of vanilla extract for added depth of flavor.
Whisk together the all-purpose flour, baking powder, and salt in a separate bowl. Gradually add this dry mixture to the butter mixture, stirring until just combined. Be careful not to overmix!
Fold in the mint chocolate chips, mini marshmallows, and half of the vibrant green confetti sprinkles. This step brings all that festive goodness together!
Spread the mixture evenly in the prepared baking dish, ensuring it reaches the corners for even baking. A spatula works wonders here!
Sprinkle the remaining confetti evenly over the top, adding a playful finish that will sparkle when baked.
Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean. The edges should be lightly golden.
Cool the bars completely in the baking dish before cutting them into squares. This patience pays off with perfectly cut treats!

Optional: Serve warm with a scoop of vanilla ice cream for an extra indulgent treat.

St Patrick’s Mint Marshmallow Confetti Bars Recipe FAQs

What kind of butter should I use for this recipe?
I recommend using unsalted butter for the best flavor balance, but you can substitute it with coconut oil if you’re aiming for a dairy-free version. The oil will provide the same moisture richness while keeping those minty flavors intact.

How long can I store St Patrick’s Mint Marshmallow Confetti Bars?
You can store these delightful bars in an airtight container at room temperature for up to one week. If you’d like them to last longer, refrigerate them in a sealed container for up to two weeks. They taste best when brought back to room temperature!

Can I freeze these bars for later use?
Absolutely! To freeze, cut the bars into squares, wrap them tightly in plastic wrap or aluminum foil, and place them in a freezer-safe container. They can be frozen for up to 3 months. When you’re ready to enjoy, simply thaw them in the fridge overnight or microwave them for 10-15 seconds to recreate that gooey deliciousness.

What should I do if my bars are too gooey or don’t set properly?
If your bars come out too gooey, it may be due to underbaking. Always check for doneness by inserting a toothpick; it should come out clean or with just a few crumbs. If you find they are too soft after baking, let them cool completely in the pan, as they will firm up as they chill.

Are these bars suitable for people with allergies like gluten or dairy?
Yes! You can make St Patrick’s Mint Marshmallow Confetti Bars gluten-free by substituting all-purpose flour with gluten-free flour blends. Use coconut oil instead of butter for a dairy-free option. Plus, always check your mix-ins, like mint chocolate chips and sprinkles, to ensure they align with dietary needs. This way, everyone can indulge in the fun!
