Lace Cookies

Anyone who knows me knows I was raised not only by a wonderful mother, but another set of amazing women – The Sisters of Mercy.  Well, not all of them – but quite a few.  See, my Aunt is a nun – has been for 70 years now, so her band of sisters became de facto aunts to me and I wouldn’t want my life any other way.  Who would not want to surround themselves with women who’s entire purpose is to provide mercy and comfort to others.  In my years with many Sisters, I’ve picked up a lot of recipes along the way and one of my all time favorites is Lace Cookies. These are the most delicate, exquisite, dainty, crispy cookies you will ever have.  They are paper thin and as fragile as a soap bubble.  It’s amazing how something so crunchy can melt in your mouth. And before you say “but I don’t like oatmeal cookies” try these…  if you close your eyes, I bet you won’t tell there is oatmeal there at all.

What is a lace cookie?

I suppose a lace cookie is a simpler, but no less fabulous Florentine. A Florentine is a delicate cookie made of nuts and fruit mixed with sugar and melted together with butter and honey.  The Lace cookie refines this down to the simplest form while leaving the fragile, crispy, buttery goodness intact.  Made with just 8 very simple ingredients, needing no fancy skills or equipment, and only having a little over 50 calories a cookie who wouldn’t love this recipe!  They take a little time to cook, because you can only bake a few at a time, and it takes a very gentle hand to peel them from the foil when they’ve cooled but you will make these again and again.  They are a HUGE hit at the holidays, but don’t ask me why – I like them all the time. Oh, want to know WHY they’re called lace cookies?  Because they create these tiny holes giving the cookie the appearance of fine lace.  Take a look…

What makes lace cookies so thin?

Two things really, butter and sugar.  The softer the butter, the more it spreads in the oven.  When you’re making cookies that you’re going to roll and cut out, you want to make sure your dough goes in the fridge before baking so the butter is nice and solid when you pop them in the oven.  With lace cookies, you’re starting out with the butter already melted.  And while sugar is a solid at room temperature, it liquifies when it heats up so the only things in this recipe holding these cookies together at all are the oats and the tiny bit of flour.  Here… let me show you how thin these are going to be.

How to make lace cookies:

Grab your eight ingredients: quick cook oats, sugar, vanilla, an egg, baking powder, sugar, salt, and melted butter.  That’s it.  Preheat your oven to 350F and let’s get started.

Lace Cookies Recipe

First, melt your butter in a medium bowl and slightly beat your egg.

Add all of the ingredients to the melted butter and stir well until  thoroughly combined – it’s going to be really thin and runny.  Line a cookie sheet or baking tray with aluminum foil and use about one teaspoon of dough for each cookie.  Do not put more than 6 on a standard size cookie sheet or, trust me, they will run together.

Each cookie should be about 2″ in diameter, but really no more than 21/2″.

Bake for about 12 minutes.  It could be a little shorter so start checking around the 10 minute mark.  Depending on the size they could take up to 15.  With the high sugar and butter content, they will go from just slightly underdone to burnt in the blink of an eye.  Slide the foil off the baking tray and let cool completely.

Once completely cooled VERY VERY gently peel them off the foil.  They are extremely delicate so take your time – no need to rush.  But… if you should crumble a few, sprinkle them over ice cream for a wicked treat.
