Ingredients You’ll Need
The cake base begins with softened unsalted butter, granulated sugar, one large egg, vanilla extract, all-purpose flour, baking powder, salt, and milk. Softened butter blends smoothly with the sugar and helps create a creamy batter, while baking powder gives the cake a gentle lift.
The topping uses a separate amount of all-purpose flour, granulated sugar, packed light brown sugar, ground cinnamon, salt, and melted unsalted butter. Brown sugar contributes a deeper caramel note, and cinnamon gives the crumb layer its familiar bakery aroma.
- Use unsalted butter: This lets you control the salt in both the cake and topping.
- Use room-temperature butter for the cake: It beats more evenly with the sugar.
- Measure flour carefully: Weigh it when possible, or spoon it into a measuring cup and level the top.
- Prepare the pan: Greasing and lining a 9-inch square pan makes serving and lifting the cake much easier.
Gather every ingredient before mixing. Because the topping comes together quickly, having the flour and sugars ready keeps the process calm and prevents overworking the crumbs.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), then grease and line a 9-inch square baking pan with parchment. Leave a little parchment overhang on two sides so you can lift the cooled cake from the pan without disturbing the crumb topping.
Step 2: Prepare the crumb topping before making the batter. Whisk together 1 1/2 cups flour, the granulated sugar, brown sugar, cinnamon, and 1/8 teaspoon salt, then stir in the melted butter until large, irregular crumbs appear.
Step 3: Stop mixing as soon as the topping forms chunky pieces. Fine, sandy crumbs usually mean the mixture has been worked too much, so gently squeeze a few portions together with your fingers if you want especially generous clusters.
Step 4: In a clean bowl, whisk together the cake flour, baking powder, and 1/2 teaspoon salt. Separately, beat the softened butter and 3/4 cup granulated sugar for about 2–3 minutes, until the mixture looks light, creamy, and slightly fluffy.
Step 5: Beat the egg and vanilla into the butter mixture until smooth. Add the dry ingredients in two or three additions, alternating with the milk, and mix only until no large streaks of flour remain.
Step 6: Scrape the batter into the prepared pan and spread it evenly from corner to corner. The batter will be thick, so use the back of a spoon or a small offset spatula to create an even layer before adding the topping.
Step 7: Scatter the crumb mixture generously over the entire surface. Do not press the topping firmly into the batter; simply distribute it evenly and allow the pieces to sit on top, with some larger chunks grouped together.
Step 8: Bake for 32–38 minutes, checking near the shorter end of the baking range. The cake is ready when it is golden and a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
Step 9: Cool the cake in the pan for 20–30 minutes, or until it is comfortably cool to handle, then continue cooling completely for the cleanest slices. Lift it using the parchment and dust with confectioners’ sugar just before serving if desired.
Pro Tips for Chunky, Tender Crumbs
The signature topping depends on restraint. Once the melted butter has been incorporated, stop stirring; large irregular pieces create the classic crumb-cake appearance and provide a satisfying contrast to the tender center.
Flour measurement is especially important here because both the cake and the topping contain a substantial amount. Too much flour can make the base dense and dry, so weighing the flour is the most reliable method, followed by the spoon-and-level technique.
Do not skip the creaming time for the cake batter. Beating the softened butter and sugar for 2–3 minutes helps produce a lighter texture, but mixing too long after adding flour can make the finished cake less tender.
Keep the topping on the surface rather than stirring it into the batter. The separate layers are what give this cake its recognizable look and allow the cinnamon crumbs to bake into a golden, buttery crust.

Serving, Storage & Reheating
Serve the cake in nine generous squares or cut it into smaller bites for a brunch platter. It is delicious at room temperature with coffee, black tea, or a glass of cold milk, and the optional confectioners’ sugar adds a pretty finish without making the cake overly sweet.
For the cleanest slices, wait until the cake has cooled completely. The crumb topping firms as it cools, so cutting while the cake is still hot may cause the pieces to break apart and the topping to slide.
- Short-term storage: Keep the cooled cake covered at room temperature.
- Serving later: Dust each portion with confectioners’ sugar shortly before serving.
- Refreshing a piece: Warm it gently if desired, taking care not to overheat the crumb topping.
- Serving suggestion: Pair a square with fresh fruit for a simple breakfast plate.

Common Questions
Can I make the crumb topping ahead? Yes, the topping can be mixed first and set aside while you prepare the cake batter. Keep the crumbs loosely grouped rather than compacting the entire mixture into one mass.
Why did my crumbs turn out small? The topping was likely stirred or rubbed together too much after the butter was added. Next time, mix only until large pieces form and gently press a few crumbs together by hand.
How do I know when the cake is done? Look for a golden surface and test the center with a toothpick. It should come out clean or with a few moist crumbs, not wet batter.
Can I cut it while warm? You can, but the slices will be less neat and the topping may be fragile. Cooling completely gives the crumb layer time to set and makes the cake easier to portion.
Easy Crumb Cake Recipe
Ingredients
Method
- Heat the oven to 350°F (175°C). Grease and line a 9-inch square baking pan with parchment, leaving enough paper over the sides to help lift out the cooled cake.
- Make the crumb topping first by whisking the flour, granulated sugar, brown sugar, cinnamon, and salt. Stir in the melted butter just until large, irregular crumbs form, then set the topping aside.
- Whisk the cake flour, baking powder, and salt together in a separate bowl. In another bowl, beat the softened butter and granulated sugar for 2–3 minutes, until light and creamy.
- Beat the egg and vanilla into the butter mixture. Add the dry ingredients in two or three additions, alternating with the milk, and mix only until the batter is combined.
- Spread the batter evenly in the prepared pan. Scatter the crumb mixture generously over the surface, pressing a few portions together if you prefer larger pieces.
- Bake for 32–38 minutes, until the cake is golden and a toothpick inserted in the center comes out clean or with a few moist crumbs. Cool the cake in the pan before cutting, then dust with confectioners’ sugar if desired.
