Step by Step Instructions
Here are step by step photos and instructions on how to make this lucky charms rice krispie treats recipe! For the full ingredient list and method, see the recipe card at the end of this post.
STEP 1: Brown the butter. In a large saucepan over medium heat, brown the butter. As the butter melts, stir it with a rubber spatula to encourage even cooking. Once the butter has fully melted, it will alternate between rapid large bubbles and gentle small foamy bubbles. The butter will be ready once it turns a dark golden color and the fat solids have darkened and settled at the bottom of the pan.
STEP 2: Add marshmallows and vanilla. Once the butter has browned, turn the heat down to low and add the 12 oz bag of marshmallows and vanilla. Stir frequently until fully melted, then remove from heat.
STEP 3: Fold in cereals. Immediately fold in the lucky charms and rice krispies cereals until nearly fully coated in the melted marshmallow. Lastly, mix in the reserved lucky charms marshmallows and additional mini marshmallows.
STEP 4: Pour in pan and chill. Moving quickly, pour the rice krispie treat mixture out of your large pot into the prepared pan or baking dish. Grease the bottom of a small measuring cup or spoon with butter and use to pack the mixture into an even layer. Top with additional lucky charms marshmallows, if desired. Cover the rice krispie treats and allow to set at room temperature for one hour or in the fridge for 20-30 minutes. Use a sharp knife greased with butter to cut the rice krispie treats into 16 squares, and enjoy!

Baking in Grams
All of the recipes on this blog are carefully developed with gram measurements so you can easily recreate them in your own kitchen with success. Volume measurements are extremely inaccurate and leave room for significant errors. Not all measuring cups are made equally, so your one cup of flour will be different from my one cup of flour. By providing precise measurements in grams (aside from minor ingredients, which are given in tsp/tbsp), you can make these recipes accurately and with less cleanup! All you need is this kitchen scale.
If this still isn't enough to convince you, I have provided volume measurements in the recipe card. If you are interested in understanding the conversions, this is the best conversion chart.
But trust me, once you try baking in grams you'll never turn back!
Happy baking! x
