If you’re the sort of person who loves big cookies and hates sharing, you’ve come to the right corner of the internet. Over the last couple of years, I’ve posted three “One Big” cookie recipes: chocolate chip, chocolate M&M, and snickerdoodle. Each one is a super small-batch version of a classic that yields exactly one big cookie for one hungry person (or two people, if you’re nicer than me).
You’d think after posting three single-serve cookie recipes on this site, I’d be able to churn out a new one in my sleep, but you’d be wrong. This lone oatmeal cookie? It took 27 tries. Twenty. Seven. That’s the highest number of concentrated tests I’ve ever done for one recipe.
Despite the fact that all my single-serve cookies start with similar basic ingredients and proportions, formulating them is always an adventure. The simplest recipes always seem to be the most challenging for me. Everything has to fit together just right or it’s not worth the effort. It’s like my hero, Martin Scorsese said, “There’s no such thing as simple. Simple is hard.”
The good news about this recipe, though, is that while it was hard to get it exactly right, it is very simple. Oh, and it makes one kickass, golden brown, chewy as all get-out oatmeal cookie. Oh my goodness, it is so good. Trust me—I’ve bitten into 27 cookies to get this one exactly right. Quality control, you know?
Like all my One Big cookies, the ingredients here are measured by the spoonful rather than in cups. Oats replace some of the usual flour (duh) and I’ve added a hint of cinnamon for that classic oatmeal cookie flavor. You’ll notice that there’s no egg in this dough, as I prefer to use water for such a tiny portion. As a bonus, no egg means this recipe can easily be made vegan! Just swap vegan butter for the dairy butter ☺️ 
The big secrets to golden, chewy oatmeal cookie success? Before baking, press down on the dough ball to form a puck. This encourages a consistent shape, texture and browning pattern. Nothing terrible will happen if you don’t press down your dough ball, but your cookie likely won’t look like mine.
Also, let the dough rest for five minutes at room temperature before baking. This dough is sticky and might over-spread a bit if baked immediately after mixing. By letting it “set up” for five minutes before baking, we’re ensuring thicker, chewier results.
As far as mix-ins go, use whatever you like. I went for classic oatmeal raisin for photos, but rest assured that I made a few with chocolate chips, too. Nothing but the most thorough cookie testing here at E2 Bakes.
Have a good weekend, y’all. Make yourself a cookie.
One Big Oatmeal Cookie
makes 1 large cookie
1 tablespoon unsalted butter, melted
2 tablespoons light or dark brown sugar, packed
1 teaspoon water (not cold)
1/8 teaspoon pure vanilla extract
2 tablespoons all-purpose flour
2 tablespoons old-fashioned oats
1/8 teaspoon ground cinnamon
1/8 teaspoon baking soda
pinch of Kosher or sea salt
2 tablespoons raisins (or semisweet chocolate chips), plus more for optional topping
Preheat oven to 350F. Line a baking sheet with parchment. Set aside.
In a small bowl, use a fork to whisk together melted butter and brown sugar. Mix in water and vanilla. Add flour, oats, cinnamon, baking soda and salt, and whisk until a dough forms. Use a silicone spatula or spoon to mix/fold in raisins (or chocolate chips).
Use your hands to form dough into a ball and place on parchment. Dot with additional raisins (for aesthetic purposes), if desired. Use the heel of your hand to press down gently on the dough, just so that the dough is a 1-inch thick puck.
Let dough puck rest on the parchment for 5 minutes before baking.
Bake for 13-14 minutes or until edges have darkened to a golden brown color and center is still a bit pale.
Let cookie cool on the pan for 5-7 minutes before using a spatula to remove it to a plate. Enjoy warm or at room temperature.
Hello from Swan’s Island, Maine! I’m here with friends, enjoying the ocean views and crunchy leaves and I would never like to leave, thank you very much. We’ve been keeping busy doing as much or as little as we want—hiking, going to the beach, thrifting, watching TikTok, playing with my ring light, crafting…
As usual, I have kind of taken over the kitchen. It’s just what I do, I suppose. I’ve made a couple of blog recipes (
Easy Pumpkin Oatmeal takes ten whole minutes and is hardly even a recipe. Just toast some oats and then add some water and milk (I used almond). Bring it to a simmer and cook, stirring constantly, for about five minutes or until creamy. Finish it off with some pure pumpkin purée, 
I dished this up with cinnamon apples, vegan butter and maple syrup. I highly recommend eating it in your pajamas in a living room overlooking a lobstering wharf on a fall morning, but if you’re not currently situated on an island in Maine, any dining table will do.
Heads up that I’m going to take this Friday off of posting so I can enjoy my vacation, but I’m posting all our Maine meals over on 
Did you know you can make a 
Well, I didn’t. It hadn’t even occurred to me until I made 
Not only is this oven pancake completely whole grain, it’s also naturally gluten-free! If you or a fellow breakfast guest needs to be gluten-free, make sure your oats are certified gluten-free.
If you’re wondering if this Oatmeal Puff Pancake is more work than the traditional version, the answer is “no.” Just like its gluten-full counterpart, the batter comes together in under 90 seconds in a blender, then goes directly into a super hot, buttery pan, then into the oven for 18 minutes.
The pancake is ready when the edges are golden brown and the center is beginning to take on color. It will also likely (but not always) have a few large bubbles, which will quickly disappear as the puff relaxes into a smoother bowl shape at room temperature.
Once it’s deflated, fill your Oatmeal Puff Pancake with your favorite seasonal fruit (I went with the last of the plums and blackberries) and drizzle with maple syrup, or go more traditional with lemon and confectioner’s sugar. Then slice into this custard-centered beauty and behold its crisp-chewy edges.
Like other Dutch Baby recipes, this Oatmeal Puff Pancake can be scaled up or down depending on the size of your pan and how many servings you need. I’ve included times and proportions for four different yields in the recipe notes to make sure that there’s plenty to go around.
Just like clockwork, every August I crave old back-to-school lunchbox favorites. Yes, I know I am a childless adult who is more than a decade away from her last first day of school, but I guess it’s pavlovian. In years past, it’s been 
Now, I already have a recipe for a homemade version of 
Oatmeal Creme Pie Bars, y’all! These sweet squares are a cross between a thick cookie and a 
The cookie layer is a streamlined version of my usual Oatmeal Creme Pie dough, made with quick oats (homemade or store bought) and a hint of cinnamon. The only “major” change is the addition of a tiny spoonful of baking powder for a little extra lift. The batter comes together in minutes before being spooned into a pan, then baked until golden at the edges and nearly cakey in the middle, the way all good Oatmeal Creme Pies are.
The marshmallow frosting is a take on my usual Oatmeal Creme Pie filling. It’s super smooth and a bit glossy in the best possible way. In the past, I’ve used shortening in my Oatmeal Creme Pie filling for maximum nostalgia, but swapped it for butter here with good results.
This batch of Oatmeal Creme Pie Bars came together in a relative flash—less than two hours top to tail, including cooling—meaning you might have time to whip some up soon, regardless of the fact that lunchboxes may not be a part of your life right now, whether it be because school is virtual or because you’re a 35 year old childless adult with a snack cake habit.
