Here's a Kosher Pareve cookie recipe I worked up using some of the corn/soy/dairy-free Kosher for Passover products available this time of year. I modified my mom's famous chewy oatmeal cookie recipe, using crushed matzo (also spelled matza, matzoh, or matzah, or in Hebrew מַצָּה maṣṣā) crackers instead of oats.
If you need a Kosher for Passover recipe, substitute matzo meal for the flour and K for P sugar or honey for the brown sugar. You may need to add a tablespoon or more extra flour if using a liquid sweetener, and the texture won't be the same.
I also tried the recipe with 2 tablespoons less margarine (6 tablespoons total) and 1/2 cup brown sugar with 1/4 cup honey. That worked fine although the texture and flavor weren't quite as good.
1/2 cup Kosher for Passover Pareve margarine (I used Mother's brand regular salted margarine)
3/4 cup brown sugar (C & H is corn-free, pure cane sugar)
1 cup flour (I used King Arthur White Whole Wheat)
1/2 tsp. baking soda
1/4 tsp. additive-free salt (kosher salt or unrefined sea salt)
2 large matzo crackers, coarsely crushed (makes almost 1 cup of crumbs)
1/2 to 1 cup of your favorite cookie mix-in (optional)
1/2 tsp. flavoring of your choice (optional)
Preheat oven to 375 degrees F. Crush the Matzos. I broke mine in quarters and put them in a sandwich bag, then pounded the bag with a blunt object (the bottom of my sea salt canister) to crush them.
Cream together margarine and sugar. Add egg and mix well. If you wish to add a safe vanilla or another liquid flavoring, stir this into the wet ingredients with the egg.
In separate bowl, mix flour, baking soda and salt. If you are adding cinnamon or another dry flavoring, add it to the dry mixture.
Add dry ingredients to sugar mixture and stir just until blended. Mix in the matzo crumbs. If desired, stir in your favorite cookie mix-in (i.e. raisins, baking chips, candy, dried fruit or nuts).
Drop in small spoonfuls onto a cookie sheet and cook for 8 to 10 minutes. Remove from the oven while they still look soft and shiny in the center for cookies with a chewy texture; they will continue to cook a bit after you take them out of the oven. I baked mine for just 8 minutes and immediately removed them from the pan to a cooling rack.
Makes about 30 cookies.
