From Start to Finish: Crumb Cake

Step 1: Prepare Your Ingredients
Start by gathering all your ingredients. Preheat your oven to 350°F (175°C) and grease your baking pan to prevent sticking.
Step 2: Make the Crumb Topping
In a bowl, combine 1 cup + 2 tablespoons of all-purpose flour, 1/3 cup packed light brown sugar, 1/3 cup granulated sugar, 1 teaspoon ground cinnamon, and 1/4 teaspoon salt. Pour in the melted butter and mix until the mixture resembles coarse crumbs. Set aside.
Step 3: Prepare the Cake Batter
In another bowl, whisk together 1 cup of all-purpose flour, 3/4 teaspoon baking powder, 1/8 teaspoon baking soda, and 1/4 teaspoon salt. In a separate mixing bowl, cream together 5 tablespoons of softened unsalted butter and 1/2 cup granulated sugar until light and fluffy. Beat in the large egg and 1 teaspoon of vanilla extract. Gradually mix in the dry ingredients, alternating with 1/4 cup milk and 1/4 cup sour cream, until just combined.
Step 4: Assemble the Cake
Pour the cake batter into your prepared baking pan, spreading it evenly. Sprinkle the crumb topping generously over the batter, ensuring it covers the surface well.
Step 5: Bake
Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden brown and the crumb topping should look deliciously crunchy.
Step 6: Cool and Serve
Once baked, remove the cake from the oven and allow it to cool in the pan for about 10 minutes before transferring it to a cooling rack. Let it cool completely before slicing into squares. Enjoy your homemade crumb cake with a cup of coffee or tea!
Seasonal Adaptations
- Fall: Add chopped apples or pears to the batter for a fruity twist.
- Winter: Incorporate some ginger or nutmeg for a warm, spiced flavor.
- Summer: Mix in fresh berries or a lemon zest for a refreshing touch.
- Spring: Top with a light glaze made from powdered sugar and lemon juice for a sweet finish.
Missteps & Fixes
Sometimes things don’t go as planned in the kitchen. Here are some common missteps when making crumb cake and how to fix them:
- If your crumb topping is too dry, add a bit more melted butter until it reaches the right consistency.
- If the cake is too dense, ensure you’re measuring your flour correctly—scooping directly from the bag can pack it too tightly.
- If the cake is over-baked and dry, consider reducing the baking time by a few minutes next time or checking for doneness a little earlier.
- If the cake sticks to the pan, ensure it is well-greased or lined with parchment paper before pouring in the batter.
Keep It Fresh: Storage Guide
To keep your crumb cake fresh and tasty, follow these storage tips:
- Store the cake in an airtight container at room temperature for up to 3 days.
- For longer storage, wrap the cake tightly in plastic wrap and refrigerate for up to a week.
- You can also freeze the crumb cake for up to 3 months. Just make sure it’s well-wrapped to prevent freezer burn.
- To enjoy frozen cake, simply thaw it overnight in the refrigerator before serving.
Common Questions
Can I use whole wheat flour instead of all-purpose flour?
Yes, you can substitute whole wheat flour, but the texture may be denser. It’s best to use a combination of both for a lighter crumb cake.
What can I use instead of sour cream?
You can replace sour cream with plain yogurt or buttermilk for a similar tangy flavor and moisture.
Can I make this crumb cake ahead of time?
Absolutely! This crumb cake holds up well and can be made a day in advance. Just store it in an airtight container at room temperature.
How do I make my crumb cake extra flavorful?
In addition to cinnamon, consider adding a dash of nutmeg or vanilla bean paste for an extra layer of flavor. You can also mix in chocolate chips or nuts for added texture.
