How to Make St Patrick s Mint Marshmallow Confetti Bars
Prepare Baking Pan: Preheat your oven to 350 °F (175 °C) and grease a 9 9-inch baking pan with unsalted butter or cooking spray. This will prevent sticking and help your bars come out perfectly!
Cream Butter and Sugars: In a mixing bowl, beat together 1 cup of unsalted butter, 1 cup of granulated sugar, and 1 cup of brown sugar until the mixture is fluffy and light in color, which should take about 2-3 minutes.
Add Eggs and Vanilla: Incorporate 2 large eggs, one at a time, mixing well after each addition. Then, add 1 teaspoon of vanilla extract for that warm, inviting flavor.
Mix Dry Ingredients: In a separate bowl, whisk together 2 cups of all-purpose flour, 2 teaspoons of baking powder, and ½ teaspoon of salt until well combined. This step incorporates air and ensures even rising.
Combine Mixtures: Gradually add the dry ingredients to the creamed mixture, mixing until just combined. Avoid overmixing to keep your bars light and soft.
Fold in Add-ins: Gently fold in 1 cup of mint chocolate chips, 1 ½ cups of mini marshmallows, and ½ cup of green confetti sprinkles. This adds all the delightful textures and colors!
Bake: Spread the batter evenly in the prepared pan and bake for approximately 30 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.
Cool and Cut: Once baked, allow the bars to cool completely in the pan before cutting into squares. This helps them set perfectly and makes them easier to handle.
Optional: Drizzle with melted chocolate for an extra decadent finish!
