Gooey Nutella Condensed Milk Cookie Bars

I hate nutella but i love this cookie bar.  Hehe..  Statement melampau aku hari ni.  But seriously,  if you love nutella,  you would love this cookie bar version.  Sedap sedap dan sedap.  Haaa..  Three times kesedapan. Makan satu slice,  nak tambah lagi, lagi dan lagi.  Before you know it, it's gone! Pastu menyesal sebab pikir the calorie that you have consumed.  Sigh.. 

GOOEY NUTELLA CONDENSED MILK COOKIE BARS

Adapted from butter baking

Ingredients
125g salted butter, melted (1/2 cup)
1 egg
1/2 cup brown sugar, packed
2 tsp vanilla extract
1 tsp instant espresso powder (a must!)
1½ cups plain flour
½ tsp baking soda
½ - 1 cup Nutella, to taste
1/4 cup condensed milk (about half a can)
1/2 cup dark chocolate chips (optional)

Method
Preheat the oven to 180 C (350 F) and line an 8x8 inch pan with baking paper.
In a medium bowl, combine the melted butter, egg, both sugars, coffee and vanilla, stirring well.
Mix in the flour, baking soda and salt until just incorporated.
Reserve about half a cup of dough and press the remaining mixture into the base of the prepared tin.
Drop spoonfuls of the Nutella evenly over the cookie dough base. Sprinkle the dark chocolate chip.
Pour the condensed milk over the top.
Crumble chunks of the reserved cookie dough on top, in an even layer.
Bake for about 30 minutes, until golden and mostly set.
If you can, allow to cool completely before cutting into pretty squares.
