Q1: Why did my cookies spread into one giant blob?

You didn't space them far enough apart! This is the most common mistake. You must leave at least 3 inches of space around each small spoonful of dough.

Q2: Why are my cookies soft and chewy, not crispy?

The two most common culprits are that you underbaked them or you are trying to eat them before they have cooled completely. They will be very soft and limp when they first come out of the oven, but they will "crisp up" as they cool!

Q3: Can I use old-fashioned rolled oats instead of quick oats?

It is not recommended. The quick-cooking oats are the non-negotiable secret to the "lace" texture. They are thinner and more broken-down, which is the key that allows them to spread into that beautiful, delicate, web-like pattern. Old-fashioned oats are too thick and heavy.

Q4: Can I make these gluten-free?

Yes, easily! To make this recipe gluten-free, simply substitute the all-purpose flour with an equal amount of your favorite gluten-free all-purpose flour blend (that contains xanthan gum), and be sure to use certified gluten-free quick-cooking oats.

Q5: Can I add nuts or chocolate chips?

You can, but you must add them very sparingly. If you add too many "chunky" mix-ins, you will weigh down the batter and it will not be able to spread into that classic, paper-thin "lace" shape. About 1/4 cup of very finely chopped nuts would be the maximum.

Ingredients

½ cup butter
¾ cup white sugar
1 large egg, beaten
1 cup quick cooking oats
3 tablespoons all-purpose flour
1 teaspoon vanilla extract
¼ teaspoon salt
¼ teaspoon baking powder

Instructions

Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
Heat the butter in a microwave-safe bowl in the microwave until melted.
Stir the sugar into the melted butter and mix to combine.
Add the beaten egg and mix well.
Stir in the quick-cooking oats, flour, vanilla extract, salt, and baking powder until just combined.
Drop spoonfuls of the dough onto the prepared baking sheet, placing them 3 inches apart (as the dough will spread significantly).
Bake in the preheated oven for about 8 minutes, until the edges are golden brown.
Let the cookies cool completely on the baking sheet before carefully removing them.

Notes

This is a classic ‘lace cookie’ recipe, which means the dough is very thin and will spread significantly during baking. Be sure to space the spoonfuls 3 inches apart.
Lining the baking sheet with parchment paper is essential, as the sugary, thin cookies will otherwise stick.
The cookies are very delicate when hot. It is crucial to let them cool completely on the baking sheet before attempting to remove them, or they will fall apart.
