Heat oven to 350°
Place 2 cups of sliced almonds on a pan & bake for 8-10 minutes until golden. Remove from oven and cool while making the bars.
Grease a 9x13" baking pan.
In a mixing bowl, combine & mix well:
3/4 c. butter
3/4 c. brown sugar
1 egg yolk
1-1/2 c. flour
Press into the bottom of the prepared pan & bake for 20 minutes or until it's lightly golden. Put on a wire rack.
While the crust is baking, in a heavy sauce pan, combine:
2 Tblsp. butter
1- 14 oz. can sweetened condensed milk
Over medium heat, stir the mixture continuously until it begins to get bubbly. Cook & continue stirring for 5 minutes. It'll seem to get thin, but after a few minutes will thicken. After 5 minutes of stirring, remove from heat. By this time, the crust should be finished baking.
Spread the filling evenly over the baked crust - return to the oven and bake for additional 12-14 minutes, until the top becomes golden/light brown.
Remove from oven and immediately sprinkle top with 2 cups of semi-sweet chocolate chips. Return to the oven and bake for one more minute - remove and spread the melted chocolate evenly over the top. Immediately, sprinkle the chocolate with the toasted almonds.
Cool completely - cut into small bars.
