Chocolate, Oat, and Hazelnut Sandwich Cookies

Course: Holiday Recipes, Sweets
Sweets Sub-Category: Chocolate, Cookies
Servings: 20 sandwich cookies
Buttery, nutty, and deeply chocolaty, these sandwich cookies are a sophisticated twist on a childhood favorite. Made with a blend of all-purpose, oat, and hazelnut (or almond) flours, the cookies are tender with a hint of chew and a rich cocoa finish. A touch of crème fraîche in the dough adds tang and depth, balancing the sweetness and enhancing the texture.
The filling is a simple, silky ganache made from dark chocolate and butter… elegant, rich, and just the right amount of indulgent. We love using TCHO chocolate here at The Gourmandise School for its clean melt and bold flavor, which makes even the simplest ganache shine.
Crisp at the edges, soft in the center, and sandwiched together with velvety chocolate, these cookies are perfect for gifting or savoring with a cup of coffee during a quiet holiday moment.
