These delicate and crispy oat Florentine cookies are sandwiched with a rich chocolate layer, making them a delightful treat for any occasion.
Preheat your oven to 375°F and line baking sheets with foil.
Using foil ensures the cookies don't stick and makes cleanup easier.
Melt the butter in a medium saucepan over low heat, then remove from heat.
Stir the butter occasionally to prevent it from browning.
Stir in the oats, sugar, flour, corn syrup, milk, vanilla extract, and salt until well combined.
Ensure the mixture is evenly combined for consistent cookies.
Drop level teaspoons of the batter onto the prepared baking sheets, spacing them about 3 inches apart. Flatten slightly with a spatula.
Flattening the batter helps the cookies bake evenly.
Bake for 6-8 minutes or until golden brown. Let cool on the baking sheets before transferring to a wire rack.
Watch closely as the cookies can brown quickly.
Melt the chocolate chips in a microwave-safe bowl, stirring every 15 seconds until smooth.
Avoid overheating the chocolate to prevent it from seizing.
Spread a thin layer of melted chocolate on the flat side of half the cookies, then top with the remaining cookies to create sandwiches.
Let the chocolate set slightly before serving for a cleaner presentation.
Serve the cookies on a platter and enjoy with your favorite beverage.
These cookies pair wonderfully with coffee or tea.
