Chocolate Caramel Linzer Cookies are delicate chocolate sandwich cookies made with a buttery cocoa dough and filled with sweet, chewy caramel for a rich and elegant treat.
Start by making your caramel sauce, pour the sugar into a large saucepan. Cook on medium heat, whisking the sugar until melted. The sugar will clump up first, but will eventually completely melt/caramelize.
Once the sugar has melted, stop whisking. Remove caramel from the heat. Add the butter and whisk until combined.
Slowly pour the heavy cream into the caramel and whisk until incorporated. Cool for about 10-15 minutes before using.
Get the oven preheating to 350°F degrees.
In a large bowl beat the butter, sugar, egg, vanilla extract, and milk with an electric mixer until creamy.
In a separate bowl combine the flour, cocoa powder, sea salt, and baking powder. Add the dry ingredients into the butter mixture, mixing in between additions.
Encase the dough between two sheets of parchment paper. Use a rolling pin to roll the dough out to about 3-4 mm thick.
Use a Linzer cookie cutter or a cookie cutter of your choice to cut out the solid bottoms. Transfer them to a parchment paper lined baking sheet. Repeat until you've cut 12-15 solid shapes.
Next, you'll cut the cookie tops, which, instead of being solid, have a cut-out shape (where the caramel is going to go). You can either bake the cut-outs as mini cookies, or you can combine the dough and roll out additional cookies, making sure to have a top & bottom for each whole cookie.
Bake in a preheated oven for 6-8 minutes. Let cool 1-2 minutes on pan, then transfer to a cooling rack.
Fill the cookies with caramel, position top & bottom of cookies with the flat side positioned into the center. Pick up the top and spoon 1 tsp caramel onto bottom of cookie, directly into the center, where the cut out will go. Place the top of the cookie onto the caramel, so that most fills the cutout, but just enough is also on the underside of the cookie as to securely attach the cookie sandwich together.
Repeat with remaining cookies. Serve & enjoy!
