Yes, PLEASE!

I was looking up recipes for cookie bars tonight in hopes of finding something wonderful to get out of the rut of the recipes I've made dozens of times (hee hee pun intended!).
And I found this jewel.
At least I hope it's a jewel, the ingredients look more than promising! Check it out...
Sadly, there were no pictures.
Do I want to try these? Do I want these for my birthday (less than a month away now!)?
Yes, PLEASE! (although I'm thinkin' leave out the walnuts, what are they in there for?)

Coffee Bars
The rocky tops on these luscious bar cookies come from chocolate-covered coffee beans and crushed toffee bars.

3/4 cup butter or margarine, softened
3/4 cup firmly packed brown sugar
1 egg yolk
1 1/2 cups all-purpose flour
1 tablespoon instant coffee granules
1/4 teaspoon salt
1 (14-ounce) can sweetened condensed milk
2 tablespoons butter or margarine
1 tablespoon Kahlúa or strong brewed coffee
1 cup chopped walnuts
1 cup chocolate-covered coffee beans, chopped
1 cup coarsely chopped English toffee-flavored candy bars

Beat 3/4 cup butter at medium speed of an electric mixer until creamy; gradually add brown sugar, beating well. Add egg yolk, beating well. Add flour, coffee granules, and salt, stirring just until blended. Using greased fingers, press dough into bottom of a lightly greased 13" x 9" x 2" pan. Bake at 350° for 20 minutes. Set aside.

Combine sweetened condensed milk and 2 tablespoons butter in a saucepan. Bring to a boil over medium heat; cook 5 minutes, stirring often. Remove from heat, and stir in Kahlúa. Pour mixture over prepared crust. Sprinkle with walnuts.

Bake at 350° for 10 to 12 minutes or until golden. Remove from oven. Sprinkle with chopped coffee beans and toffee bars while still warm. Cool completely in pan on a wire rack. Cover and chill until firm. Let stand 5 minutes before cutting into bars.
