New York–style crumb cake is all about contrast: a soft, buttery vanilla cake base topped with a thick layer of cinnamon-sugar crumbs that are almost as abundant as the cake itself. It’s a classic you’d find in bakeries across New York City—perfect with coffee or as a cozy breakfast treat.
Here’s a detailed, recipe with step-by-step directions.
New York–Style Crumb Cake
Ingredients
For the Crumb Topping:
- 1 cup brown sugar (light or dark)
- ½ cup granulated sugar
- 1 tablespoon ground cinnamon
- ¼ teaspoon salt
- 1 cup unsalted butter, melted
- 2½ cups all-purpose flour
For the Cake Batter:
- 2½ cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- ½ teaspoon salt
- ¾ cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 cup sour cream
- 2 teaspoons vanilla extract
Step-by-Step Directions
Step 1: Prepare the pan and oven
Preheat your oven to 350°F (175°C).
Grease and line a 9×13-inch baking pan with parchment paper for easy removal.
Step 2: Make the crumb topping
In a large bowl, mix together:
- brown sugar
- granulated sugar
- cinnamon
- salt
Pour in the melted butter and stir until combined.
Add the flour and mix until large, thick crumbs form. The mixture should be chunky, not sandy.
Set aside.
Step 3: Mix the dry ingredients for the cake
In a separate bowl, whisk together:
- flour
- baking soda
- baking powder
- salt
Set aside.
Step 4: Cream butter and sugar
In a large mixing bowl, beat the softened butter and sugar together until light and fluffy. This takes about 2–3 minutes.
Step 5: Add eggs and flavoring
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract.
Step 6: Add sour cream and dry ingredients
Mix in the sour cream until smooth.
Gradually add the dry ingredients, mixing just until combined. Do not overmix.
The batter will be thick.
Step 7: Assemble the cake
Spread the batter evenly into the prepared pan.
Break the crumb mixture into large chunks and scatter generously over the top. Press very lightly so they stick but remain chunky.
Step 8: Bake
Bake for 40–45 minutes, or until:
- the crumbs are golden brown
- a toothpick inserted into the cake comes out clean
Step 9: Cool and serve
Allow the cake to cool in the pan for at least 20–30 minutes before slicing.
Dust with powdered sugar if desired.
Tips for the Perfect Crumb Cake
- The crumb layer should be thick and uneven—that’s the signature look
- Use room-temperature ingredients for a smoother batter
- Avoid overmixing to keep the cake tender
- Sour cream adds moisture and a slight tang—don’t skip it
Serving Ideas
- Serve warm or at room temperature
- Pair with coffee or tea
- Add a side of fresh berries for balance
New York–style crumb cake is simple but indulgent, with its buttery base and generous crumb topping making every bite rich, soft, and slightly crisp on top.
