Ingredients

Scale

Cinnamon Crumble

¾ cup melted butter (1½ sticks)
1½ cups all-purpose flour
¾ cup brown sugar
1 tablespoon ground cinnamon
½ teaspoon ground nutmeg

Coffee Cake Batter

½ cup butter, softened
1 cup white sugar
2 eggs
1 teaspoon vanilla extract
⅔ cup sour cream
1 cup all-purpose flour
1 teaspoon ground cinnamon
½ teaspoon baking powder
½ teaspoon salt

Instructions

Preheat Oven: Preheat your oven to 350˚F (175˚C) to ensure it’s at the perfect temperature when your cake is ready to bake.
Make Cinnamon Crumble: In a medium bowl, combine melted butter, 1½ cups flour, brown sugar, cinnamon, and nutmeg. Stir with a fork until mixture becomes crumbly and well combined, forming a cinnamon crumble topping.
Prepare Cake Batter: In a large bowl, cream together the softened butter and white sugar using a hand mixer or wooden spoon until the mixture is light and fluffy. Add eggs one at a time, mixing well after each addition, then mix in vanilla extract. Fold in sour cream carefully until incorporated.
Mix Dry Ingredients: In a separate bowl, combine 1 cup flour, cinnamon, baking powder, and salt. Gradually add these dry ingredients into the wet butter mixture, stirring gently until just moistened. Avoid overmixing to keep the cake tender.
Assemble the Cake: Grease an 8-inch square baking dish thoroughly. Spread half of the coffee cake batter evenly on the bottom of the dish. Sprinkle half of the cinnamon crumble on top of the batter. Carefully spread the remaining batter over the crumble layer, then finish with the remaining cinnamon crumble on top.
Bake: Place the baking dish in the preheated oven and bake for 42 to 50 minutes. Check for doneness by inserting a toothpick into the center — it should come out clean when the cake is fully baked.
Cool and Serve: Allow the cake to cool for about 5 minutes in the pan. Then cut into 16 squares and serve warm or at room temperature, ideally alongside a hot cup of coffee or your favorite beverage.

Notes

Ensure butter is softened for easy creaming and better batter texture.
Do not overmix the batter once the dry ingredients are added to maintain a tender crumb.
The cake is best served fresh but can be stored in an airtight container at room temperature for up to 2 days.
For extra richness, you can add chopped nuts to the crumble mixture.
If you prefer a tangier flavor, substitute sour cream with Greek yogurt.
