Moonie, Wormtail, Padfoot, and Prongs ... ok, just Moonie

Good things are a-brewin’. First of all, Switzerland was awesome! A giant thanks to Jan and Kim. I am still living on a little bit of a high from that trip, so I am taking all of life’s little annoyances in stride. I am also getting very close to making a large shift in my career path. Just knowing what is on the horizon is giving me daily energy and a better outlook on life. Last, and certainly not least… look at those cookies! I think these are the most amazing cookies I have made to date. I absolutely do not want to wait to eat one! The marshmallow filling is perfect. These cookies are a pretty large time commitment since they are completely from scratch, but man, is it worth it. Seriously…. these cookies will make you a star.

Big thanks to Nan Slaughter @ Pots and Pins for this recipe.

INGREDIENTS (makes 12-15 cookies)

Cookies:

  • 1 cup sugar
  • 5 tbls butter, softened
  • 1 tspn vanilla
  • 2 large eggs
  • 2 cups all-purpose flour
  • 5 tbls unsweetened cocoa
  • 1 tspn salt
  • 1 tspn baking soda
  • 1 tspn baking powder
  • 1 cup buttermilk

Filling:

  • 1 envelope unflavored gelatin
  • 1/2 cup cold water
  • 1/2 cup sugar
  • 1/4 cup light-colored corn syrup
  • 1/8 teaspoon salt
  • 1/2 teaspoon vanilla
  • 1/4 cup cold water

DIRECTIONS

Preheat your oven to 375ºF.

First thing to make will be the cookies. In a large bowl, combine the butter and sugar. Beat it together until blended. Add in the eggs and vanilla and beat it together until it is fluffy. In a separate bowl combine the flour, cocoa, salt, baking soda, and baking powder. Whisk it together until its all nice and mixed.

Now go back to your first bowl with the wet ingredients and start adding the dry ingredients and buttermilk a little bit at a time. Do this while mixing the batter, and alternating buttermilk and dry ingredients as you go. Scrape down the bowl a few times and make sure that the batter is well mixed.

On a parchment lined cookie tray, start spooning heaping tablespoon sized cookie batter. Leave a couple of inches between the cookies so that they don’t touch while cooking. Bake each tray for 9-10 minutes until fully cooked (use a toothpick to test). Let the cookies cool for a few minutes and then move them to a cooling rack. Keep baking until all the batter is used up. (should be about 30 cookies)

The filling is the fun part of these cookie sandwiches. First put the 1/2 cup of water in medium to large mixing bowl. Sprinkle the gelatin powder into the bowl and set it aside.

In a small saucepan put the other 1/4 cup of water, sugar, corn syrup, salt, and vanilla. Heat it on the stove until it reaches 244ºF. Apparently some people have a thermometer in their kitchen, so use that if you got it. I just waited for it to just start to simmer and then called it a success (my filling turned out great). Pour the hot liquid into the gelatin bowl and start mixing. Start by mixing on low for a little bit and then turn up the speed to max. The mixture will start to froth a bit and eventually will work itself into a thick foam. It supposedly takes anywhere from 6-10 minutes for the filling to get thick enough to use, but for me it took a little bit longer.


I think it has to do with the temperature… it needs to cool adequately before it will start to set. Anyways, you’ll get there. Now start spooning giant blobs of fluff onto the bottom of your cookies, using a second cookie on top to make a heavenly sandwich. Let the cookies set for an hour (or less if you are impatient).

Now pour a glass of milk and eat up!
