Now, use a spatula to mix in the finely chopped almonds. ￼
Then scoop out about 1/2 tablespoon-sized scoops of the cookie dough onto a baking sheet lined with a silicone mat. If you don’t have a silicone mat, parchment paper works too. But the mats will result in more even baking.
Make sure to place each scoop of the lace cookie dough at least 3 inches apart. They will spread a lot when they bake.
Now preheat your oven to 325 degrees Fahrenheit. Then take each piece of cookie batter and roll it out to a ball, and place it half onto the baking sheet.
Place each baking sheet in the center rack (one at a time). Then bake for 8 minutes making sure to turn once after 4 minutes.
While the cookies are looking, melt 1 1/2 cups of semisweet chocolate in a microwave-safe bowl until fully melted. Always be sure to do this in intervals with stirring in between to avoid scorching the chocolate￼.
Now take 1 Florentine cookie and gently spread a little bit of the melted chocolate on the back of it, then place a similar sized cookie on top. So you want the back of each cookie to sandwich the chocolate in between them.
Let the chocolate set for about 1-2 hours before serving.
Use almond flour- Almond flour or fresh-ground almonds are responsible for not just the delicious flavor, but also the texture of these lace cookies. If you replace almond flour with all-purpose, these cookies will not spread to become thin and crispy, so stick with the almonds.
Trim the edges of your cookies- If your cookies come out a little irregular, you can trim them with scissors into circles, so they sandwich together just right.
Keep an eye on your melted chocolate- When microwaving chocolate, stop it every 15-30 seconds to give it a stir. This keeps the chocolate from scorching and not being heated a moment more than necessary.
