Brown Butter
Melt the butter slowly on medium heat in a saucepan. Once melted, turn the heat up a bit and watch the butter closely while continuing to stir. The butter will bubble and start to pop as the water evaporates out. Once this slows down, watch extremely closely as the next step will be the browning.
Once the solids start to roast, you'll see small bits of brown forming in the pan. Stir the spoon around the pan a few times more and remove it quickly from the heat. The butter should have swirls of browned bits in the bottom of the pan and is now ready
**This step happens very quickly. Watch closely so it doesn't burn.
Graham Cracker Cookies
Pour the browned butter (all of it) into a large bowl and let it cool for 10-15 minutes.While waiting, line a baking sheet with parchment paper or a silicone mat and set the oven to 350°F. Place graham crackers in a zip-top bag and crush them with a rolling pin until they are fine crumbs.
Add the brown sugar and granulated sugar to the cooled butter mixture and use a spoon to stir well until thoroughly combined (3 minutes).
Mix in the egg and vanilla extract until well combined.
Add the flour, graham cracker crumbs, and baking soda to the butter mixture and mix well.
Add in the mini milk chocolate chips and mix with the batter.
Use a 1/4 measuring cup to measure out 8 cookies, form each batter ball into a cookie ball, place on a baking tray and bake for 10 minutes until cookies are set.
Immediately remove the cookies from the oven, and press two marshmallow halves into the top of each cookie, overlapping them slightly.
Turn the oven on to the broiler setting to high.
Broil cookies, watching closely, for about 2 minutes or until marshmallows are lightly golden.
After browning the marshmallows, allow the cookies to cool for 10-15 minutes before adding the chocolate drizzle and graham cracker crumbles to the top.
