Dutch Bokkenpootjes – Goat's Feet

Step 1
Beat egg whites until foamy in a large glass or metal mixing bowl. Gradually add the white sugar, continuing to beat until stiff peaks form. Lift your beater or whisk straight up: the egg whites should form a sharp peak that holds its shape. Fold in the almond meal, cinnamon, lemon zest, and vanilla.

Step 2
Line a baking sheet with parchment paper. Transfer the meringue to a piping bag with a large plain tip (or a gallon-sized plastic zipper bag with the corner snipped off). Pipe the meringue into ladyfingers about 3 inches long. Set the pan aside and let the meringues dry at room temperature for 2 hours.

Step 3
Preheat an oven to 320 degrees F (160 degrees C).

Step 4
Bake the cookies on the middle oven rack until dried but not yet brown, 15 to 20 minutes. Allow them to cool completely.

Step 5
Make the filling by creaming the butter and confectioners' sugar until smooth. Stir in the vanilla. Meanwhile, melt the chocolate in the top of a double boiler over just-barely simmering water, stirring frequently and scraping down the sides with a rubber spatula to avoid scorching.

Step 6
To assemble the cookies, spread buttercream on the back of a cookie, sandwich it together with another cookie, and dip both ends in the melted chocolate. Let the dipped cookies dry on waxed paper or parchment.
