Oatmeal Lace Cookies

Lace cookies are, for me, the taste of the holiday season.

And spring.

And fall.

…And summer.

I make them a lot.

There’s just something about these crisp, so-thin-you-can-see-through-them cookies that just is everything I want out of a dessert. Plus, all of the ingredients are cheap and available at any grocery store, and the recipe makes enough for days of sweet snacking.

Beyond that, the best thing about this recipe in particular is its history.

This has literally been passed down in my wife’s family for generations. Her grandmother made these heavenly cookies for her dad, and he made them for my wife (and, later, myself).

And now, I will share them with all of you.

Quick thing: I have included affiliate links to Amazon below – it won’t affect your price to click them, but I do get a kickback. I promise that my links are only to be helpful and offer products that would be useful with the recipe.

Lace Cookies 00 - Ingredients

Ingredients

Now, I’m going to give you a good step-by-step explanation, but if you’d rather skip that and just go straight to the short-form recipe, I have included it at the bottom of this post.

So, first things first: getting the ingredients. Don’t bother with the cart at the grocery, you only need seven things: salted butter, light brown sugar, rolled oats (sometimes called “old-fashioned”), all-purpose flour, salt, egg, and vanilla.

Real quick: I said light brown sugar because it has a lighter flavor than the dark. Also, I say rolled/old-fashioned oats because they are whole oats, not ground or chopped. My first batch was with steel-cut oats, though, and actually turned out ok. So don’t panic if that’s all you have.

Making the batter

So, let’s begin. Preheat the oven to 375 F.

Lace Cookies 01 - Heating Brown Sugar and Butter

Then, put two sticks of butter (that’s one cup) into a sauce pot over medium-low heat along with two and a quarter cups of packed brown sugar. Stir it pretty frequently until the mix is smooth.

Lace Cookies 02 - Melted butter and brown sugar
All smooth!

Then, you are going to add the rest of the ingredients. However, this can trip folks up a bit, because depending on the order you could end up frustrated or with chunks of scrambled egg throughout.

Luckily, I know the secret to fixing the problem. So, follow this order.

Lace Cookies 03 - Adding flour, salt, and vanilla

First, add the flour (three tablespoons), salt (one teaspoon), and vanilla (one teaspoon). Mix it until nice and smooth.

Lace Cookies 04 - Adding the oats

Next, add two and a quarter cups of oats and mix.

Lace Cookies 05 - After adding the egg

Finally, beat one egg and mix it in. The photo above is after adding the egg.

I know, it seems weird to add the biggest dry ingredient before the egg, but trust me. If you add the egg before the oats, then no matter how fast you mix you’ll end up with bits of scrambled egg mixed into your batter.

Baking the Cookies

Your batter is now ready to bake. However, lace cookies are easy to burn, and if you do them wrong you might end up with a cookie-shaped chunk of charcoal.

Luckily, once again I know the secret fix.

Lace Cookies 07 - Uncooked cookies

Line a cookie sheet with parchment paper, then drop spoon-sized dollops of dough onto the sheet about two inches apart. I actually use a cookie scoop, which makes it way, way easier. If you want one of your own, you can click on the image to the left to go to one on Amazon.

Bake for around 7 minutes.

Lace Cookies 08 - Not done yet
These cookies are not done yet.

After that, your cookies should be thin and flat. Bubbles will be forcing their way through the batter, creating the namesake lace-like holes.

Lace Cookies 09 - Finished baking
These cookies are ready to take out of the oven.

Your cookies are done when they are the golden color of caramel and the bubbles have slowed. The first batch generally takes about 9-11 minutes for me, but it doesn’t take too long for these to burn, so I still go for 7 minutes to start.

Like my mom always said, you can always put them back in for more time, but burnt is burnt.

Lace Cookies 10 - Cooling the cookies

Transfer the first parchment paper, cookies and all, onto a cooling rack or countertop, then push a fresh piece back on the cookie sheet, add some more batter, and throw that sucker back in.

I recommend that once you start cooking lace cookies, you keep going until they are all gone. Once more, there is a reason to my madness.

The batter is made with egg and butter, so you can’t just leave it sitting out. But, if you put a lid on that pot and put it in the fridge, the batter will stiffen up and dry out.

Heating leftover batter back up is slow and annoying. I only did it once before I decided, “Never again.”

Lace Cookies 11 - Transfer to cooling rack

When the cookies have cooled somewhat, remove them from the parchment paper and transfer to a cooling rack. Luckily, this takes about as long as the next batch takes to cook.

So, slap that just-used parchment paper back on that cookie sheet for a new batch (don’t worry, it’s safe to do so – I double-checked).

Store your delicious, crunchy cookies in an airtight container. I just throw them in quart-size freezer bags.

They won’t last long enough to go bad. Trust me.

Quick Story: Don’t Forget the Salt

Ok, so funny story – when my wife and I got married, we included this recipe (along with two others) in a miniature recipe book for table favors. When I used one of the books to make a batch of cookies, though, I realized that I had left out one extremely important ingredient: the salt.

Without salt, lace cookies taste like slightly sweet flour. My wife, dear thing, told me it wasn’t all that bad. However, I noticed she didn’t take another bite.

We ended up shaking salt on them to rescue them. There was no way I was going to let a whole set of lace cookies go to waste, gross or not.
