1 ½ cups salted butter (for both the cake and crumb topping; ensures rich flavor)
1 cup light brown sugar, tightly packed (adds moisture and depth)
¾ cup granulated sugar (for sweetness)
4 cups all-purpose flour (for structure; spooned and leveled for accuracy)
2 tablespoons ground cinnamon (for warmth and flavor)
Powdered sugar for dusting (optional, adds a lovely finishing touch)
2 ¾ cups all-purpose flour (also for the cake; spooned and leveled, ensuring a good rise)
1 teaspoon baking powder (helps the cake rise)
1 teaspoon baking soda (adds to the fluffiness)
½ teaspoon salt (balances sweetness)
¾ cup salted butter, softened (for the cake, enhances creaminess)
1 cup granulated sugar (additional sweetness)
3 large eggs, room temperature (promotes even mixing)
1 teaspoon vanilla extract (adds a lovely aroma)
¾ cup full-fat sour cream, room temperature (provides moisture and richness)

How to Make Crumb Cake

Preheat the oven: Begin by preheating your oven to 350°F. Prepare a 9×13 baking pan by spraying it with cooking spray or lining it with parchment paper to ensure easy release after baking.
Make the crumb topping: In a medium, microwave-safe bowl, melt 1 ½ cups of salted butter in 30-second intervals. Stir in 1 cup of tightly packed light brown sugar and ¾ cup of granulated sugar. Next, fold in 4 cups of all-purpose flour and 2 tablespoons of ground cinnamon until a cohesive dough forms. Set this aside; it should resemble a thick paste.
Combine dry ingredients: In another medium bowl, mix together 2 ¾ cups of all-purpose flour, 1 teaspoon of baking powder, 1 teaspoon of baking soda, and ½ teaspoon of salt. Whisk until everything is well combined and set aside.
Cream wet ingredients: In a large bowl, cream together ¾ cup of salted butter and 1 cup of granulated sugar with an electric mixer until the mixture is light, fluffy, and well-combined. Add in the three large eggs one at a time, ensuring each is fully incorporated. Then, mix in 1 teaspoon of vanilla extract and ¾ cup of room-temperature full-fat sour cream until everything is blended together.
Combine wet and dry ingredients: Gradually add the dry ingredients to the wet mixture, mixing until the batter thickens. The batter should be spooned into your prepared baking pan and spread out evenly across the bottom.
Top with crumble: Break the crumble topping into pebble-sized pieces, about ½ inch, and evenly sprinkle it over the cake batter. This topping is the star, so cover the cake consistently.
Bake: Place the baking pan on the middle rack and bake for 45-50 minutes. Keep an eye on it, and if the crumble is browning too much by the 45-minute mark, slip a sheet of aluminum foil over the top. It’s done when a toothpick inserted into the center comes out clean and the crumble has turned a nice golden color.
Cool and serve: Let the crumb cake cool on a wire rack at room temperature before serving. Dust with powdered sugar if desired for an elegant finish.

Storing & Reheating

To store your leftover crumb cake, cover it with plastic wrap and keep it at room temperature for up to three days. For longer storage, move it to the refrigerator where it’ll stay fresh for about a week. If you’re looking to save some for later, freeze slices in an airtight container for up to three months. When you’re ready to indulge again, simply reheat in a preheated oven at 350°F for about 10-15 minutes. Just know that the crumb may soften a little once frozen, so enjoy it warm for the best experience!

Chef’s Helpful Tips

Make sure your eggs and sour cream are at room temperature. This helps with even mixing, making for a better-textured cake.
Don’t skip the dusting of powdered sugar; it adds a lovely touch of sweetness and visual appeal.
Leave a toothpick in longer for a slightly crumbly cake, or pull it out sooner for a more moist texture.
If you want to wow your guests, try adding a layer of fruit like blueberries or apples between the cake and the topping for an extra burst of flavor.
This recipe is forgiving if you need to adjust the sugar—feel free to cut down on the sugar if that’s your preference.

Baking your crumb cake not only fills your home with a cozy scent, but it also fills your heart with warmth. Every slice boasts a unique combination of textures and flavors that will keep you returning for more. So don’t hesitate to experiment with your toppings or add-ins, making this recipe truly your own.

Recipe FAQs

What is the best way to store crumb cake?

Crumb cake is best stored at room temperature, covered tightly in plastic wrap or foil, for up to three days. For longer storage, refrigerate or freeze to keep it fresh. If freezing, slice and place in an airtight container; it lasts up to three months.

Can I make this crumb cake gluten-free?

Absolutely! Replace the all-purpose flour with a 1:1 gluten-free flour blend. The texture may vary slightly, but it will still be delicious. Ensure that other ingredients, like baking powder and vanilla extract, are also gluten-free.

What can I substitute for sour cream?

If you don’t have full-fat sour cream on hand, you can use Greek yogurt or buttermilk as a substitute. Both options contribute moisture and a creamy texture to the cake.

Can I add fruit to the crumb cake?

Yes! Adding fruits like blueberries, raspberries, or even thinly sliced apples between the cake and the crumble topping can elevate the flavor profile. Just be mindful not to add too much moisture, which could alter the cake’s consistency.
