Ingredients You’ll Need

½ cup milk: Adds moisture and richness. Whole milk is recommended for the best flavor.
½ tablespoon white vinegar: Used to sour the milk, creating a homemade buttermilk that enhances tenderness.
2 cups multipurpose gluten-free flour: This keeps the cake gluten-free while still yielding a fluffy texture. Choose one with xanthan gum for the best results.
1 ½ teaspoons baking powder: This provides lift and helps the cake rise beautifully.
1 teaspoon baking soda: Another leavening agent that contributes to the cake’s fluffiness.
½ teaspoon kosher salt: Enhances the overall flavor, balancing the sweetness.
4 rounded tablespoons cornstarch mixed with 6 tablespoons water: This serves as an egg substitute to bind the ingredients together, keeping it vegan-friendly.
½ cup unsalted butter or vegan baking stick: Adds richness and flavor. If using vegan butter, ensure it is at room temperature.
1 cup granulated sugar: Sweetens the cake and balances the tanginess of the sour cream.
¾ cup sour cream: Important for moisture and gives the cake its characteristic tang.
1 ½ teaspoons pure vanilla extract: Enhances the sweetness and adds depth to the cake’s flavor.
2 tablespoons granulated sugar: Used for the cinnamon-sugar topping for a delightful crunch.
½ teaspoon ground cinnamon: Adds a warm, aromatic spice to the topping.
1 ¼ cups multipurpose gluten-free flour: For the crumb topping, maintaining a gluten-free option.
½ cup light brown sugar: Imparts a rich caramel flavor to the crumb topping.
¾ teaspoon ground cinnamon: Enhances the flavor of the streusel topping.
½ cup unsalted butter or vegan baking stick, melted: Binds the crumb topping, resulting in a satisfying crunch.
Confectioners’ sugar: Optional for dusting before serving, adding a touch of sweetness.

How to Make Sour Cream Coffee Cake

Preheat and Prepare the Pan: Start by preheating your oven to 350 degrees Fahrenheit. Grease a 9-inch springform pan with vegetable oil, then line the bottom with parchment paper and lightly grease the paper. This step ensures easy release after baking.
Make Homemade Buttermilk: In a bowl, combine ½ cup milk with ½ tablespoon white vinegar. Stir and let it sit for 5-10 minutes until it looks slightly chunky; this is your homemade buttermilk.
Mix Dry Ingredients: In a large mixing bowl, whisk together 1¾ cups multipurpose gluten-free flour, 1½ teaspoons baking powder, 1 teaspoon baking soda, and ½ teaspoon kosher salt until evenly combined. Set aside.
Prepare Cornstarch Mixture: In a medium bowl, mix 4 rounded tablespoons cornstarch with 6 tablespoons water until you achieve a smooth, thin consistency. This mixture will act as a binder in the absence of eggs.
Cream Butter and Sugar: In a large bowl, beat together ½ cup unsalted butter (or vegan baking stick) with 1 cup granulated sugar using an electric mixer until the mixture is soft and creamy, about 1-2 minutes.
Incorporate Buttermilk and Vanilla: Gradually mix the cornstarch mixture into the creamed butter and sugar. With the mixer on low, blend in ¾ cup sour cream and 1½ teaspoons pure vanilla extract until the mixture appears slightly chunky but well-combined.
Combine Batters: Slowly add the dry flour mixture to the sour cream mixture, mixing just until combined. Next, drizzle the homemade buttermilk into the batter while gently stirring until the mixture is cohesive. Scrape the sides to ensure everything is integrated.
Prepare Cinnamon Sugar: In a small bowl, whisk 2 tablespoons granulated sugar with ½ teaspoon ground cinnamon. This will later be sprinkled between the layers of batter.
Layer the Batter: Using a spatula, spread half of the batter into the springform pan and smooth the top. Sprinkle the cinnamon sugar evenly over this layer. Carefully top with the remaining batter, smoothing it as best you can without disrupting the cinnamon sugar layer.
Make the Crumb Topping: In another bowl, combine 1¼ cups gluten-free flour, ½ cup light brown sugar, and ¾ teaspoon ground cinnamon. Melt ½ cup unsalted butter in a heat-safe bowl (cover with a paper towel to avoid splatter) and whisk it until creamy. Pour the melted butter into the dry ingredients and mix until crumbly, using your hands to form small clumps.
Top the Cake: Sprinkle the crumb mixture evenly over the batter. It’s fine if the crumbs pile up; this will add to the delicious texture.
Bake: Place the cake in the center of your preheated oven and bake for 75 minutes, or until a skewer inserted into the center comes out clean. Once baked, allow the cake to cool completely in the pan to retain moisture.
Dust and Serve: After the cake has cooled, dust it lightly with confectioners’ sugar if desired. Slice and enjoy!

Storing & Reheating

To store your Sour Cream Coffee Cake, keep it at room temperature covered in plastic wrap for 1-2 days. For longer storage, place it in the refrigerator where it will stay fresh for up to a week in an airtight container. You can freeze the cake for up to 3 months. When ready to enjoy, thaw it in the fridge overnight and reheat gently in the oven at 350°F for about 10-15 minutes to refresh its texture.

Chef’s Helpful Tips

Be careful not to overmix the batter once you add the flour. It can toughen your cake.
Always use room temperature ingredients, especially the butter and sour cream, for a smoother batter.
For even baking, ensure your oven is fully preheated before placing the cake inside.
If your crumb topping is too dry, simply add a touch more melted butter until you achieve the right consistency.
Consider adding nuts or chocolate chips for extra flavor and texture!

Recipe FAQs

Can I make this cake dairy-free?

Yes! You can substitute the milk with any plant-based milk and use a dairy-free sour cream alternative. There are several great options available in stores today.

How can I ensure my cake doesn’t stick to the pan?

Greasing the pan well and lining it with parchment paper is key. You could also dust the pan with flour after greasing to create an extra non-stick layer.

Can I use regular flour instead of gluten-free flour?

Absolutely! If you don’t need the recipe to be gluten-free, feel free to use regular all-purpose flour in the same quantities.

How do I know when the cake is done baking?

A toothpick or skewer inserted into the center of the cake should come out clean or with just a few moist crumbs. Keep an eye on the edges; they should be golden brown.
