From Start to Finish: Classic Crumb Cake

Step 1: Preparation
Start by preheating your oven to 350°F (175°C). Grease your 9×13 inch baking pan generously with butter to ensure easy removal of the cake later.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the 2 cups of all-purpose flour, baking soda, baking powder, and salt. Set this mixture aside while you prepare the wet ingredients.
Step 3: Cream the Butter and Sugar
In a large mixing bowl, cream together the 10 tablespoons of unsalted butter and 1 cup of granulated sugar until the mixture is light and fluffy. This process should take about 3-5 minutes using a hand mixer or stand mixer.
Step 4: Add the Eggs and Vanilla
Beat in the 3 large eggs one at a time, ensuring each egg is fully incorporated before adding the next. Then, mix in the 1 teaspoon of vanilla extract until everything is well combined.
Step 5: Incorporate the Sour Cream
Add the 1 cup of sour cream to the butter mixture, mixing until smooth. This will give your cake that deliciously moist texture.
Step 6: Combine Wet and Dry Ingredients
Gradually add the dry ingredient mixture to the wet mixture, stirring gently with a rubber spatula until just combined. Be careful not to overmix; a few lumps are perfectly fine.
Step 7: Prepare the Crumb Topping
In a separate bowl, combine the 3 cups of all-purpose flour, 1 cup of packed light brown sugar, 1 tablespoon of ground cinnamon, and 1 teaspoon of coarse salt. Mix these dry ingredients well. Then, add the 1 cup of room temperature unsalted butter. Use your hands or a pastry cutter to mix everything together until you achieve a crumbly texture.
Step 8: Assemble the Cake
Pour the cake batter into the prepared baking pan, smoothing the top with a spatula. Then, sprinkle the crumb topping generously over the cake batter, ensuring an even layer.
Step 9: Bake
Place the pan in the preheated oven and bake for 40-45 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Step 10: Cool and Serve
Once baked, remove the cake from the oven and let it cool in the pan for about 15 minutes. After that, transfer it to a cooling rack to cool completely before serving. Enjoy your Classic Crumb Cake with a dusting of powdered sugar or a dollop of whipped cream if desired!
Make It Year-Round

There are countless ways to customize your Classic Crumb Cake to suit the seasons:
- Fall: Add diced apples or pears to the batter for a fruity twist.
- Winter: Incorporate chocolate chips or nuts for added texture and flavor.
- Spring: Use fresh berries mixed into the cake or as a topping.
- Summer: Try adding a layer of lemon zest for a refreshing citrus flavor.
What Could Go Wrong
Even the best bakers encounter mishaps. Here are a few common pitfalls and how to avoid them:
- Dry Cake: Ensure you measure your flour accurately. Too much flour can lead to a dry texture.
- Sunken Center: Make sure your oven is properly preheated, and avoid opening the door too early during baking.
- Crumb Topping Too Dense: If you overmix the crumb topping, it will lose its texture. Mix just until combined.
- Sticking Cake: Don’t forget to grease the pan thoroughly; you can also use parchment paper for an extra layer of protection.
Storing, Freezing & Reheating
Classic Crumb Cake is a great make-ahead dessert. Here’s how to store and enjoy leftovers:
Store leftover crumb cake in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze slices wrapped in plastic wrap and then placed in a freezer bag for up to 3 months. To reheat, simply thaw at room temperature or warm individual slices in the microwave for about 15-20 seconds. Enjoy it warm for a freshly baked taste!
