Hello, I have a problem with my cookies spreading too. I never had this problem only with this recipe, Mocha brownie sandwich cookies. I made them twice and the first time they were airy and flat the second time just flat and chewy not edible. I threw them away. What went wrong? Recipe calls for baking chocolate and bittersweet chocolate and milk chocolate and cocoa powder. Maybe too much chocolate? I thought perhaps using baking soda vs baking powder was the problem.
