Dulce de Leche Sandwich Cookies

So excited when found this recipe online yesterday nite!! could not wait, since is cookie making, nothing complicated in the making process, therefore quickly went ahead baking though is already almost 10pm!! ^-^ waited patiently for the cookie to cool down....took a piece and taste it....crunchy & sweet caramel taste! :) took another piece & spread with my Dulce de Leche....oh so addicting but is SWEEETTTTT !!! >< maybe I seldom take so sweet stuffs, I prefer munching on the plain caramel cookies instead :P

this picture reminds me of my failed macarons did previously hahaha...

Ingredient (30 sanchwich cookies)

• 150gm plain flour, sifted
  
• 1 tsp baking soda
• 1/4 teaspoon salt
• 110gm unsalted butter
• 100ml dulce de leche, plus more for filling
• 60gm light brown sugar
• 40gm sugar
• 1 large egg

Method

1. In a medium bowl, whisk together the flour, baking soda and salt.
2. Using a electric whisk, beat the butter at medium speed until just softened and broken up a bit. Add dulce de leche, brown sugar and granulated sugar. Beat on medium speed until light and fluffy, about 3 minutes. Add the egg, beating to incorporate.
3. Reduce the mixer speed to low and add the dry ingredients all at once. Mix only until the flour is just combined.
4. Spoon the dough onto the lined baking sheets using a heaping teaspoon of dough (do not drop too large dough if not you will get a jumbo cookie!) for each cookie. The dough is soft & spread a lot during baking therefore leave 2 inches of space between each cookie for the baking spread.
5. Baked in preheated oven at 180 deg cel for 10 to 12 minutes. The cookies will be honey brown with a light crust, but still very soft when they come out of the oven. Let them rest on the cookie sheet for a minute or two before removing to cool.(will harden upon cooling)
   
6. Once the cookies are cooled completely, spread them with dulce de leche and sprinkle with a bit of sea salt if you like. Keep well wrapped for up to four days.
