How we perfected the ultimate coffee cake, our Recipe of the Year
The secrets are reverse creaming, crispy crumbs, and a fudgy filling.
“Perfect the coffee cake.” This was the considerable challenge handed off to Senior Recipe Developer Molly Marzalek-Kelly in the early months of 2022. Coffee cake had been selected as our 2023 Recipe of the Year after months of company-wide deliberation.
Why coffee cake? Because it’s versatile, comforting, shareable, and downright delicious. (Who can resist those crumbs?!) Plus, we knew we could improve on this classic breakfast treat, which is too often dry, crumbly, and boring. The result was our new recipe for Cinnamon-Crisp Coffee Cake, but it took months of effort and plenty of testing to get there.
Let the testing begin
Despite having well over 30 coffee cake recipes on our site already, Molly was tasked with developing a new recipe that checked a number of boxes: It had to be approachable for most bakers but still impressive; distinct in flavor and also crowd-pleasing; and make King Arthur ingredients shine but also rely on pantry staples. It was no easy task.
To my surprise, Molly looks back on her experience developing the ultimate coffee cake and says, “I remember the testing happening pretty quickly.” Some necessary context: “Pretty quickly” for the King Arthur Test Kitchen team means baking the recipe over two dozen times.
Where to start?
When this recipe's development began, the King Arthur Recipe Team — a group of bakers who help shepherd our online recipes — was pretty hot on reverse creaming, a mixing method that results in especially tender, fluffy cakes. We knew we wanted to showcase the technique in this coffee cake.
We also knew that we wanted a layer of slightly crisp crumbs on top to compliment the soft, fluffy cake beneath. After testing different ratios of brown to white sugar, amounts of butter, and baking times, the secret to crispy crumbs turned out to be two kinds of sugar: granulated for sweetness, and confectioners’ sugar primarily for texture. (There’s a bit of cornstarch in confectioners’ sugar that draws out moisture and adds crispness when baked.)
The filling also had to be special — it needed to be full-flavored and rich. Molly turned to cocoa, an ingredient that gives the filling a “fudgy” quality and, when used in the right proportion, doesn’t add a strong chocolate flavor, allowing the flavor of the cinnamon she added to shine through.
There we had it: tender reverse-creamed cake, crispy crumbs, and a fudgy filling. The trifecta that make a killer coffee cake.
Flavor brainstorm
The tinkering didn’t stop there. Once we nailed the foundational elements of the coffee cake, we wanted to see what else it could do. Could it handle double the streusel for a crumb lover's variation? Would it work with celebratory sprinkles? The base version, which we eventually named Cinnamon-Crisp Coffee Cake, turned out to be wildly adaptable.
Molly and the Recipe Team dreamt up many different versions of coffee cake that we wanted to try, from one that showcased the flavor of Vietnamese coffee, to classic peanut butter and jelly, and even milk and cereal.
We got carried away imagining seasonal flavor variations: roasted fruit in the spring, fresh berries in the summer, spices in the fall, and brown butter, coffee, and chocolate in the winter.
Before we knew it, we had over 40 different coffee cake ideas. But alas, we could only pick one.
Or could we?
Breaking the rules
For the past nine years, Recipe of the Year has showcased a single recipe all year long. But this time, we just couldn’t let go of the idea of embracing this coffee cake’s versatility.
I remember hearing Molly quietly suggest to the Recipe Team, “What if we did 10 variations of coffee cake?” My mind immediately went spinning. It’s a lot of work to develop a single recipe and bring it to life on our website. It felt like a TON of work to do this 10 times over.
But Molly seemed unintimidated, and the rest of us followed her lead. “People can bake them all to find their favorite!” “We could release them on a seasonal basis!” “10 variations for our 10th Recipe of the Year!” The Recipe Team was on board.
Looking back, Molly says she was a little naive about how difficult it would be to develop 10 variations of coffee cake, but in a way, it was also freeing. Without having to commit to a single recipe or flavor profile, her creativity could shine.
A year unlike any other
By the time 2023 is over, there will be 10 variations of the incredible reverse-creamed, slightly-crispy-crumbed coffee cake. Right now you can bake our Triple Chocolate Coffee Cake (a chocolate lover's dream and perfect midnight snack), or if you're more into the crumbs than chocolate, make our Crumb Lover's Coffee Cake. There's also the funfetti-inspired Birthday Coffee Cake, which makes the best birthday (or any special day) breakfast.
The variations that will follow in the spring and fall are just as flavorful and fun as those in the winter collection: They'll range from fruity and bright to rich and indulgent to spicy and unexpected. Bake them all to find your favorite (or should I say, favorites). I suspect we won’t be the only ones unable to commit to a single coffee cake when there are so many delicious possibilities.
And don’t stop at the flavor variations we came up with! Molly hopes bakers will feel inspired to dream up their own versions of this coffee cake too. We can’t wait to see what you come up with.
