From Start to Finish: Lucky Charms Bars

Making Lucky Charms Bars is a quick and easy process. Follow these steps to create your delicious treats:
Step 1: Melt the Butter
In a large saucepan over medium heat, melt the unsalted butter. Stir occasionally to prevent burning.
Step 2: Add the Marshmallows
Once the butter is melted, add 9 ounces of the miniature marshmallows (reserve 1 ounce for later) to the saucepan. Stir until the marshmallows are completely melted and smooth.
Step 3: Flavor It Up
Remove the saucepan from heat and stir in the vanilla extract and salt. Mix well.
Step 4: Combine with Cereal
Add the Lucky Charms cereal to the melted marshmallow mixture. Stir gently until all the cereal is well-coated.
Step 5: Add Extra Marshmallows
If you’re using the optional Lucky Charms Marshmallows, fold them in at this stage for an extra treat in every bite.
Step 6: Transfer to Baking Dish
Pour the mixture into a greased or parchment-lined 9×13-inch baking dish. Use a spatula to press the mixture down evenly. Be careful not to press too hard, or the bars may become too dense.
Step 7: Let It Set
Allow the bars to cool at room temperature for about 30 minutes. For quicker setting, you can place them in the refrigerator.
Step 8: Cut and Serve
Once set, cut the bars into squares or rectangles. Serve and enjoy the sweetness of your homemade Lucky Charms Bars!
