Almond macaroons, graham cracker crumbs and almond biscotti can all be used in place of amaretti cookies in a recipe. However, the substitute best used in place of amaretti cookies depends on the recipe.
Amaretti cookies are hard cookies that are often ground up or crumbled and added to various desserts. Amaretti cookies have an intense almond flavor because they are generally made with bitter almonds. Almond macaroons are an ideal substitute for amaretti cookies because they have a similar consistency. However, almond macaroons are not as intensely flavored as amaretti cookies. Ladyfingers can also be used in place of amaretti cookies in certain recipes.
