Brown Butter Sandwich Cookie with Rosemary Caramel

Cooking Directions:

In a small saucepan, over low heat, heat 1/2 cup butter until nut brown in color, (after foaming subsides) being careful not to burn. Remove from heat to cool.

In a bowl cream together remaining 1/2 cup butter and sugar, until light and fluffy. Add brown butter; mix well. Add egg and vanilla; beat until blended. Add flour and baking powder; mix until blended. Flatten dough into a disk and wrap in plastic wrap. Chill dough until firm, 1 hour or more.

Preheat oven to 350ºF.

Roll out dough and cut into small (2-inch) scalloped rounds. Bake on a parchment-lined cookie sheet, 8 to 10 minutes or until edges begin to brown.

Cool completely on a wire rack.

To make rosemary caramel, melt butter over low heat in a heavy sauce pan. Place sprigs of rosemary between two sheets of waxed paper and pound until flattened. Place sprigs in butter and cook over low heat for 10 minutes. Remove sprigs from butter. Add remaining ingredients; mix well. Increase heat to medium-high and bring mixture to a boil, stirring frequently. Reduce heat to medium and continue boiling, stirring frequently, until caramel reaches 242°F (use candy thermometer); remove from heat.

Spread rosemary caramel on a cookie and top with another.
