Almond Roca Cookies

Thought of my father-in-law as I made these today--he loves almond roca. I have to say, these are a great substitute! They taste awesome and look pretty when served.1 cup butter
1/2 cup brown sugar
1/2 cup white sugar
1 egg yolk
1 tsp. vanilla
2 cups minus 4 Tbsp flour
1 Tbsp. cornstarch
1 package (about 2 cups) milk chocolate chips
3/4 cup finely chopped nuts (I used almonds)

*Cream together butter, sugars and egg yolk. Add vanilla, flour and cornstarch. Spread on greased jelly roll pan. Bake at 350 for 15-20 minutes, or until edges are lightly brown. While still warm, cover evenly with chocolate chips. Return pan to oven for about 30 seconds to soften the chocolate chips, then spread them like frosting. Sprinkle with ground nuts. When cool, cut into small rectangular cookies. Enjoy!
