Florentine Cookies

Preheat the oven to 375 degrees F (190 degrees C). Line 2 cookie sheets with aluminum foil.

Melt butter in a large saucepan. Remove from heat and mix in oats, sugar, flour, corn syrup, milk, vanilla, and salt until well combined. Drop by level teaspoonfuls 3 inches apart onto the prepared cookie sheets. Spread cookies out thin with a rubber spatula.

Bake in the preheated oven until golden brown, 5 to 7 minutes. Cool on the cookie sheets.

Meanwhile, place chocolate chips in the top of a double boiler over simmering water. Stir frequently, scraping down the sides with a rubber spatula to avoid scorching, until chocolate is melted and smooth, about 5 minutes.

Peel foil from cookies. Spread melted chocolate on 1/2 of the cookies. Top with the remaining cookies.
