I promised to post my never-fail Pesach cake when I found my cookbooks, but Mrs. Doubtfire’s recipe is almost identical to mine. Mine can use an extra 1/4 cup of sugar, but I am sure it’s just as good with the lesser amount. I use walnuts ONLY, in this recipe. Other nuts don’t work well for me.
The recipe comes from the Heimische Kitchen Pesach Cookbook, and they have many wonderful recipes there.
