Brownie Cookie Dough Sandwich Cookies
Fudgy brownie bases topped with creamy cookie dough frosting and mini chocolate chips, then sandwiched together for a hybrid dessert that combines brownie richness with the nostalgic appeal of edible cookie dough. The frosting uses heat-treated flour for food safety, making it completely edible and safe. Perfect for potlucks, celebrations, or anyone craving two desserts in one bite. This version layers baked brownie rounds with silky frosting rather than layering raw doughs.
