This sour cream gluten free coffee cake has that classic rich, tender golden cake, topped with a that classic nubby, sweet streusel crumb topping.

The secrets to the best homemade coffee cake are plenty of sour cream in the batter—and extra crumbles on top!

What makes this gluten free coffee cake the best ever?

The crumb of this delicious cake is dense, but incredibly tender and moist. It’s really a golden cake, instead of a gluten free vanilla cake.

Cakes, like vanilla cake, are typically made with a liquid in the batter like milk. This cake has just 2 tablespoons of milk—and the rest of the moisture comes from sour cream.

What use is sour cream in gf coffee cake?

The sour cream makes the most tender crumb. It adds a very slight tangy flavor that cuts through the sweetness of baked goods, and tenderizes everything.

Sour cream also adds body and richness, and a makes the crumb of this cake the kind you pick up with the tines of the fork. More cases in point: one bowl gluten free banana bread and one bowl gluten free chocolate cake.

The topping is clearly everyone’s favorite part, too! The tenderness of the cake is the perfect texture contrast to the gluten free streusel topping. There’s also tons of that crisp-tender, nubby crumble topping. 

When you slice into this cake, if absolutely nothing falls off the topping, it’s terribly disappointing. Those belong to the baker, no calories at all.

Can I freeze this gf coffee cake?

Yes! This cake freezes quite well after baking, once it’s completely cooled to room temperature.

You can cut the cake into squares and serve it when it’s still a bit warm. But to freeze baked goods, they must be completely cool.

If you freeze anything that’s still warm, it will form condensation on the outside that will freeze completely solid. And as the frozen condensation melts out of the freezer, it makes the cake soggy.

I prefer to slice the cooled cake into squares, and then wrap each leftover square tightly in freezer-safe wrap. Then, defrost at 50% power in the microwave or on the kitchen counter.

If you’d like the cake to taste extra fresh, even after being frozen, you can toast it lightly after it’s defrosted. Don’t let it toast long enough to dry out, and it will be good as new!

Is there coffee in gluten free coffee cake?

No! There’s no coffee in coffee cake. It’s made to be enjoyed with a hot cup of coffee.

Over the years, I’ve come to suspect that, in some cultures, what they call a coffee cake actually has coffee baked into the batter. I assume that flavors the cake?

I only bake coffee into a cake when I’m trying to intensify the flavor of chocolate. Our gluten free vegan gluten free chocolate cake is a great example—but you don’t taste the coffee!

How to make the perfect crumb topping for coffee cake

The secret to ensuring a crumble topping that holds its shape and doesn’t simply melt into the cake batter is temperature. It’s made with melted butter to ensure easy blending—and then it must be chilled.

The butter in the crumble only has to chill as long as necessary to solidify enough to be broken up into irregular chunks. If the pieces of crumble are too small, like sand, they’ll become a candy-like layer of melted sugar.

There’s enough gluten free flour blend in the topping for the pieces of the crumble to hold their shape during baking. Press them down into the cake layer, and bake them until golden brown and crispy outside.

Substitutions for gluten free coffee cake ingredients

How to make gluten free dairy free coffee cake

There is a lot of butter in this recipe, both in the crumble topping and in the cake itself. The best replacement for the butter in both places is probably Melt or Miyoko’s Kitchen brand vegan butter.

If you can’t use one of those vegan butters, try using Earth Balance buttery sticks (but cut back on the salt a bit). For the crumble topping, if you can’t use vegan butter, try using Spectrum nonhydrogenated vegetable shortening.

For the crumble topping especially, you need something that will hold its shape during baking. Earth Balance won’t do that.

In place of sour cream, try using a good quality nondairy sour cream. You can also use plain Greek-style yogurt in place of sour cream interchangeably.

How to make gluten free egg-free coffee cake

There are two eggs in this recipe, and you might be able to replace each of them with one “chia egg” each. For each, place 1 tablespoon ground white chia seeds + 1 tablespoon lukewarm water into a small bowl, mix, and allow to gel.

If you make this recipe both egg-free and dairy-free, it will be a gluten free vegan coffee cake.

How to make gluten free corn-free coffee cake

If you can’t have corn, try using arrowroot powder or even potato starch in place of cornstarch.

If you’re already using a higher starch all purpose gluten free flour blend, like Cup4Cup, replace the 18 grams of cornstarch in this recipe with an equal amount of that high starch flour blend.

Equipment

  • Hand mixer or stand mixer

Ingredients

For the topping

  • 8 tablespoons unsalted butter melted
  • cup packed light brown sugar
  • ¼ cup granulated sugar
  • 1 cup all purpose gluten free flour blend (I used Better Batter; click for details)
  • ½ teaspoon xanthan gum omit if your blend already contains it
  • teaspoon kosher salt

For the cake batter

  • 1 ¾ cups all purpose gluten free flour blend (I used Better Batter; click for details)
  • 1 teaspoon xanthan gum omit if your blend already contains it
  • 2 tablespoons cornstarch
  • ¾ teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon kosher salt
  • 2 teaspoons ground cinnamon optional
  • 6 tablespoons unsalted butter at room temperature
  • 1 cup sour cream at room temperature
  • ¾ cup granulated sugar
  • 2 tablespoons milk at room temperature
  • 1 teaspoon pure vanilla extract
  • 2 eggs at room temperature

Instructions

  • Preheat your oven to 350°F. Line an 8-inch square baking pan with parchment paper and set it aside.

For the crumble topping

  • The topping must be prepared first, so it can chill.
  • In a medium-size bowl, place all the ingredients in the order listed, mixing to combine after each addition.
  • Cover the bowl that holds the raw topping. Place the bowl in the refrigerator to chill until firm.

For the cake batter

  • In a medium-size bowl, place the flour, xanthan gum, cornstarch, baking powder, baking soda, salt, and optional cinnamon, and whisk to combine well. Set the bowl aside.
  • In a large bowl with a handheld mixer or the bowl of a stand mixer fitted with the paddle attachment, place the butter, sour cream, granulated sugar, milk, and vanilla, and beat well on medium speed until very smooth. Add the eggs, and beat until just combined.
  • Add the dry ingredients to the bowl of wet ingredients and mix by hand until just combined. The batter will be very thick, since our liquid is mainly sour cream.

Assemble and bake the cake

  • Scrape the batter into the prepared pan and smooth into an even layer with a wet spatula. Press the spatula down in the corners to eliminate any air pockets.
  • Remove the chilled crumble topping from the refrigerator. Uncover the topping, and use the tines of a fork to break up the mixture into irregular pieces.
  • Scatter the crumble pieces evenly on top of the cake batter. Press down gently to help the topping adhere to the batter.
  • Place the cake pan in the center of the preheated oven. Bake for about 40 minutes, until the center does not jiggle in the center when the pan is shaken from side to side gently.
  • A cake tester inserted into the center should come out mostly clean. Do not overbake or the bottom will burn.
  • Remove the pan from the oven and allow the cake to cool to warm room temperature in the pan. Slice into squares and serve.
