Heres a nice flat one I use from Emily Luchetti...
Oat Crisps
Recipe By: Classic Stars Desserts by Emily Luchetti
Yield: Makes about 22 cookies
Ingredients:
1 1/4 ounces (2 1/2 T) butter, melted
1/4 cup dark brown sugar, firmly packed
2 tablespoons granulated sugar
2 tablespoons dark corn syrup
1/8 teaspoon salt (my addition)
1 cup old fashioned rolled oats
Directions:
1. Preheat oven to 350 degrees. Line 2 baking sheets with parchment paper or silpats.
2. Melt the butter and take off the heat. Add brown sugar, granulated sugar and corn syrup and whisk until blended. Using a spoon, stir in the oats and mix until they are all coated with the butter and sugar mixture.
3. Drop the cookie dough by tablespoonfuls onto prepared baking sheets, spacing them 2 1/2" apart. Bake, rotating the baking sheets at midway point, until golden brown and bubbly, about 10 - 15 minutes. Cool on the pan. Use a metal spatula to lift them off. Store in an airtight container at room temperature.
Notes:
Emily Lucchetti's recipe serves these cookies with 4 cups of blueberries and 1 cup of creme fraiche for 6 portions. Plain yogurt would probably also be very good.
Baking time in the recipe is listed as 15 minutes but mine were done in 10. Check around the 8 minute mark to see how they're doing and get a feel for how your oven wants to bake them. With these types of thin cookies and tuiles, it's really easy to go from perfect to burnt in just an extra minute.
I lined the baking sheet with silpats and let them cool completely on the baking sheet.
This would be a good cookie served alongside ice cream or crumbled as a garnish.
