Grandma Walker's Cathedral Windows
INGREDIENTS: 1/4 cup butter 2 cups semisweet chocolate chips 2 eggs, beaten 1 (10.5 ounce) package rainbow colored miniature marshmallows 1 cup chopped pecans (I used only 1/4 cup or so) 1/3 cup confectioners' sugar for decoration (optional)
Melt together the butter and chocolate chips in the top of a double boiler or in the microwave. Stir to blend, then stir in the eggs, colored marshmallows and pecans. Pour the mixture into a 9x5 inch loaf pan, lined with wax paper or cling wrap. Dust with powdered sugar (optional, I skipped it) and refrigerate until firm. Remove chilled dough from loaf pan, remove the wax paper or cling wrap, and slice into 1/4 inch slices.
Grandma use to roll them in shredded coconut too. Recipe from Allrecipes.com (same as my grandmother's)
