Chocolate Chip Cookie Dough Bars

Do you ever come across something on Pinterest and think... MUST DO IMMEDIATELY!  That's what came to mind when I came across these bars, I immediately ran to my cupboards, took inventory of my ingredients and sent the hubby out the door for an impromptu grocery run.  I couldn't wait another minute to try these bars... and the waiting for them to set up in the fridge felt like an eternity (was cravin' chocolate like it was no one's business) but they were well worth the wait!  I took them over to a friend's-get-together and they were gobbled up quickly.  I have 2 bars left and they are stashed away in the back of the freezer (unbeknownst to Aaron... shhhh don't tell him :) ) 

Cookie Dough:

1/2 c. unsalted butter, softened

3/4 c. packed light brown sugar

1 tsp. vanilla extract

2 c. all purpose flour

1 (14 oz.) can sweetened condensed milk

2 c. mini chocolate chips

Topping:

1 c. creamy peanut butter

2/3 c. milk chocolate chips

Directions:

1. In a large bowl, mix together butter and light brown sugar until light and fluffy (about 3 minutes).  Add vanilla extract and beat until combined.
2. With the mixer on low speed, alternate mixing in flour and sweetened condensed milk and mix until combined.  Gently fold in mini chocolate chips with spatula.
3. Line 8x8-inch pan with parchment paper.  Press the cookie dough into the pan (the cookie dough may be sticky, so lightly flour your hands).
4. Cover the bars with plastic wrap and refrigerate for 3 hours or overnight until firm.  
5. For topping, combine the peanut butter and milk chocolate chips in a microwave-safe bowl and heat until smooth.  Spread the mixture over the cookie dough bars.  Chill the bars for 1 hour or until topping is firm.
