Full Recipe

Ingredients

Crumb Topping

• 1 cup brown sugar
• 1/2 cup granulated sugar
• 1 tablespoon cinnamon
• 1/2 teaspoon salt
• 1 cup unsalted butter, melted
• 2 and 1/2 cups all-purpose flour

Cake

• 2 and 1/2 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1/2 teaspoon salt
• 3/4 cup unsalted butter (softened)
• 1 cup granulated sugar
• 3 large eggs
• 1 cup sour cream
• 2 teaspoons vanilla extract

Optional

• Powdered sugar for dusting

Instructions

Start by preheating your oven to 350°F (177°C). Grease or line a 9×13-inch baking pan with parchment paper for easy removal.

Begin with the crumb topping. In a medium bowl, mix brown sugar, granulated sugar, cinnamon, and salt. Stir in the melted butter until combined. Add the flour and gently mix with a fork until large crumbs form. Be careful not to overmix—you want big, chunky crumbs, not a paste. Set aside.

Now prepare the cake batter. In a bowl, whisk together flour, baking soda, baking powder, and salt.

In a separate large bowl, beat the softened butter and sugar until light and creamy. This step is key for a soft texture, so mix for about 2–3 minutes.

Add the eggs, sour cream, and vanilla extract. Mix until combined. The mixture may look slightly curdled—this is completely normal.

Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. The batter will be thick and creamy.

Spread the batter evenly into your prepared pan. Take your crumb topping and sprinkle it generously over the batter. Then gently press it down slightly so it sticks during baking.

Bake for 45–55 minutes. Start checking at 45 minutes by inserting a toothpick into the center. If it comes out clean, the cake is ready.

Allow the cake to cool for at least 30–45 minutes before slicing. Dust with powdered sugar if desired.

Tips & Tricks

The crumb topping is the highlight of this recipe, so treat it carefully. The key is to keep the crumbs large and chunky. Overmixing will turn the mixture into a dense paste, which loses that signature texture.

Using sour cream is essential. It adds moisture and richness, giving the cake its soft, tender crumb. If needed, full-fat Greek yogurt can be used as a substitute.

Room temperature ingredients make a big difference. They blend more smoothly and create a more even batter.

When pressing the crumbs onto the batter, don’t press too hard—just enough so they stick. This helps keep them from falling off after baking.

If the cake starts browning too quickly, loosely cover it with foil during the last part of baking.

Variations

One delicious variation is adding a layer of fruit between the cake and crumbs. Blueberries or sliced apples work especially well, adding a fresh and slightly tart contrast to the sweetness.

For a richer flavor, you can add chopped nuts like pecans or walnuts to the crumb topping. This adds crunch and depth, making the cake even more indulgent.

Another option is to add a drizzle of glaze instead of powdered sugar. A simple vanilla or maple glaze can elevate the cake into a more dessert-like treat.

If you love extra spice, try adding a pinch of nutmeg or cardamom to the crumb mixture for a more complex flavor profile.

Serving Ideas

This crumb cake is incredibly versatile. Serve it warm for a soft, melt-in-your-mouth texture, or at room temperature for a firmer, bakery-style bite.

Pair it with coffee, espresso, or tea for a classic breakfast or brunch experience.

For dessert, serve with whipped cream or a scoop of vanilla ice cream.

You can also cut it into smaller squares for parties or gatherings—it’s always a crowd favorite.

Storage Tips

Store leftover crumb cake tightly covered at room temperature for up to 3 days or in the refrigerator for up to 1 week.

To reheat, warm slices in the microwave for about 10–15 seconds.

This cake freezes very well. Wrap slices individually and freeze for up to 3 months. Thaw overnight before serving.
