These chocolate marshmallow cookies are for my chocolate lovers! There is a small chocolate cookie loaded with chocolate chips baked thumbprint cookie style. On top is a fluffy and melty marshmallow dipped in chocolate. To balance the flavor, don't forget the flaky sea salt!

These chocolate marshmallow cookies combine a chewy chocolate cookie with a gooey marshmallow. These are made thumbprint cookie style with a marshmallow right in the middle!
I felt the cookies needed a little more, so they are dipped in a chocolate ganache. The sea salt is a must to balance out the flavors!

Step By Step Instructions
Here are the steps to make and bake these cookies.
STEP 1: First, mix the dry ingredients. Mix all the ingredients. Use a sifter to prevent flour lumps from getting into the dough.
STEP 2: Next, beat the butter and sugars. Beat these on high to get it nice and fluffy. This helps to aerate the butter.
STEP 3: Add in the vanilla and eggs. Mix the batter until combined. Don't forget to scrape the bowl!
STEP 4: Then, add in the dry ingredients. Add in both types of chocolate chips.
STEP 5: Next, chill the dough. Chill the dough for 45 minutes. This will solidify the butter before baking.
STEP 6: Scoop the cookie dough. Use a 1 oz cookie scoop and create a heaping cookie dough ball. Bake for 8 minutes.
STEP 7: Top with half of a marshmallow. Then, bake for another 2 minutes. Squish the marshmallow down slightly.
STEP 8: Chocolate ganache. Make the ganache and dip the cookies in the chocolate. Top with sea salt.
Baking Tips
When you are making the cookie dough, it is really important to aerate the butter.
Beat the butter and the sugar on high. Beat these for several minutes. It should be incredibly fluffy. When the butter is aerated it will create a chewier cookie.
Also, make sure you chill the dough. If you want cookies that don't spread a lot, then chill the dough!
Next, squishing the marshmallow is optional. I like to have the marshmallow level with my cookie.
