I enjoyed them too when we lived in Germany but they are a lot of work. I make these and they are similar but much easier:
Raspberry Bars
2 1/2c all purpose flour
1 c sugar
1 c chopped pecans` OR walnuts
1 c butter, softened
1 egg
1 10 jar raspberry preserves
Grease a 9x13" baking pan. In a large mixer bowl, combine all ingredients except preserves. Beat at low speed until mixture is crumbly about 2-3 minutes. Reserve 1 1/2 c of crumb mixture. Press remaining crumb mixture into baking pan.
Spread preserves to within 1/2" from edges of the unbaked crumb mixture. Crumble remaining crumb mix over preserves.
Bake in a preheated 350°oven for 40-50 minutes or til lightly browned. Cool completely and cut into bars.

... they are a lot of work.

Hmmm ... while I like the challenge (at times) I am definitely going to make the Raspberry Bar recipe you posted. Thank you!

Let me know how you like them-they are a real favorite here.
I just don't have the patience to make the linzer cookies when they will just be eaten!! Guess that is why I like to make drop cookies and only a couple of rolled out ones.

I'll bet this one is good. Check out the reviews.

I remember that I made them one Christmas, when my children were little. They didn't seem to be any more trouble to make than any other cookie! Everyone loved them.

Guess there are quite a number of versions of the same thing, with the ingredients varying a bit. Whatever version....the results are well worth the trouble of making them! Not hard to make at all!
