Super Crumb Coffee Cake

A soft, tender, easy-to-make coffee cake, heavy on the crumbs!

Because the crumb part… is the best part.

If you’re anything like me, you pick off the crumb topping from your coffee cake. Or you take the piece with the most crumb topping on it. If I could make a meal out of crumb topping… believe me, I would.

This is a cinnamon, sugary, buttery crumb-topped coffee cake. Heavy on the crumb.

Today’s coffee cake is an easy-to-follow recipe. This homemade version of the classic is a far cry from any of those overly-sweet, fake-tasting store bought versions you may be used to. It’s buttery, moist, soft, and pairs well with a morning cup of coffee. Let’s face it, this coffee cake will pair well with an afternoon cup o’ joe too. Actually, the coffee is optional. You’ll love this cake no matter what you’re drinking with it.

I got the recipe from my favorite cookbook. The bible of baking, I like to call it. A 1,000+ page book of kitchen-tested recipes, tutorials, and baking tips. My Cooks Illustrated The New Best Recipe—trust me, you need this cookbook.

The cookbook doesn’t call this cake “super-crumb.” I do. I baked the crumb cake in a smaller pan than what the recipe states, making the crumb layer in my version thicker for each piece.

What makes this coffee cake so easy is that the crumb-topping and cake batter all start in the same bowl. The crumb topping’s ingredients (butter, flour, & sugar) is essentially the cake’s ingredients without any liquid. A recipe deriving both cake and crumb topping from the same mixture was a selling point for me.

Simply combine your flour, sugar, salt, and cut in the butter. I used a whisk to cut the butter in and a large fork to mix everything around until the mixture resembled course crumbs. Set aside 1 cup of the crumb mixture and continue with the rest of the cake batter ingredients.

The cup you set aside is your crumb topping. How easy is that?

The original recipe called for nuts, but I chose to leave them out. I increased the vanilla extract, cinnamon, and brown sugar as well.

In some bites, the crumb layer was thicker than the cake layer! Amazing.

Description

A soft, tender, easy-to-make coffee cake, heavy on the crumbs!


Ingredients

  • 1 Tablespoon all-purpose flour, for coating the pan
  • 2 cups (250g) all-purpose flour (spooned & leveled)
  • 1 cup + 2 Tablespoons (225g) granulated sugar
  • 1 teaspoon salt
  • 10 Tablespoons (142g) unsalted butter, firm and cold
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 3/4 cup (180ml) buttermilk, at room temperature
  • 1 large egg, at room temperature
  • 2 teaspoons pure vanilla extract
  • 2/3 cup (133g) packed light or dark brown sugar
  • 2 teaspoons ground cinnamon


Instructions

  1. Preheat oven to 350°F (177°C). Generously spray a 9-inch springform pan* with cooking spray or grease with butter. Sprinkle the bottom of the pan with 1 Tablespoon of flour and tap out the excess.
  2. Whisk the flour, sugar, and salt together in a large mixing bowl until combined. Cut in the butter in very small pieces using a pastry blender or mix with a fork until the mixture resembles coarse crumbs. Place 1 cup of the butter/flour mixture in the refrigerator until ready to use in step 4.
  3. Using a handheld or stand mixer with a paddle attachment, mix the baking powder and baking soda into the remaining flour mixture. Add the room temperature buttermilk, egg, and vanilla and beat on medium speed until smooth. The batter is very thick. Spoon the batter into the prepared springform pan, smoothing the top.
  4. Add the brown sugar and cinnamon to the reserved flour mixture. Toss with a fork until well blended. Sprinkle the crumbs over the batter, pressingly lightly so they stick.
  5. Bake the cake until the center is firm and a toothpick inserted in the center comes out clean, about 45-55 minutes. Baking time varies, so begin checking at 45 minutes and don’t be alarmed if your cake takes longer. Mine usually takes the full 55 minutes.
  6. Cool cake for 10 minutes before removing the sides of the springform pan. For neat slices and best flavor, cool cake completely at room temperature before serving.

Notes

  1. Make Ahead & Freezing Instructions: Cake tastes best on day 1 or day 2. The cake may be made 1 day in advance. Store covered at room temperature for up to 1 week. Cake can be frozen up to 2 months. Thaw overnight in the refrigerator.
  2. Special Tools (affiliate links): 9-inch Springform Pan | Glass Mixing Bowl | Whisk | Pastry Blender | Electric Mixer (Handheld or Stand)
  3. Buttermilk: Buttermilk is required for this recipe. You can make your own DIY buttermilk substitute if needed. To do so, simply add 1 and 1/2 teaspoons of white vinegar or fresh lemon juice to a liquid measuring cup and enough whole milk to reach 3/4 cup. Allow mixture to sit for 5 minutes, then use in the recipe. Lower fat or nondairy milks work in a pinch, but the cake won’t taste as rich and moist.
  4. Update: Crumbs will seep down into the cake if the crumb topping’s butter is not firm enough. Make sure the butter is cold. You can even try using frozen butter and cutting that into the mixture with your pastry blender.
  5. Pan: Don’t have a springform pan? Use a 9-inch square baking dish (not 8-inch).
  6. Adapted from Cooks Illustrated The New Best Recipe.

After one bite of this coffee cake, breakfast will seem like a real treat.
