Before You Start: Equipment

• 9×9 inch square baking pan: Perfect for even baking.
• Mixing bowls: For combining your ingredients.
• Whisk: To mix dry and wet ingredients thoroughly.

Cooking Espresso Crumb Coffee Cake: The Process

Step 1: Prepare the Crumb Topping

In a mixing bowl, combine the melted butter, granulated sugar, brown sugar, flour, instant espresso powder, ground cinnamon, and a pinch of sea salt. Use a fork or your fingers to mix until the mixture resembles coarse crumbs. Set aside while you prepare the cake batter.

Step 2: Make the Cake Batter

In a large bowl, cream together the room-temperature unsalted butter and granulated sugar until the mixture is light and fluffy. This should take about 3-5 minutes. Add the egg and vanilla extract, mixing until fully incorporated.

Step 3: Incorporate the Sour Cream

Add the full-fat sour cream to the mixture, blending well. Ensure everything is nicely mixed before moving on to the dry ingredients.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and fine sea salt. Gradually add these dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix; a few lumps are okay.

Step 5: Assemble the Cake

Preheat your oven to 350°F (175°C). Grease your baking pan and pour half of the cake batter into the prepared pan, spreading it evenly. Sprinkle half of the crumb topping over the batter. Pour the remaining batter on top of the crumbs, smoothing it out, and then finish with the rest of the crumb topping.

Step 6: Bake

Place the cake in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Keep an eye on it during the last few minutes to prevent over-baking.

Step 7: Cool & Glaze

Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a cooling rack to cool completely. While it cools, prepare the espresso glaze by whisking together the sifted confectioner’s sugar, brewed espresso (or dissolved instant espresso), and a pinch of fine sea salt until smooth. Drizzle over the cooled cake.

Spring–Summer–Fall–Winter Ideas

• Spring: Serve with fresh berries for a light and fruity twist.
• Summer: Pair with a scoop of vanilla ice cream for a delightful dessert.
• Fall: Add a pinch of nutmeg to the crumb topping for a warm, spicy flavor.
• Winter: Enjoy with a hot cup of cocoa for a cozy afternoon treat.

Mistakes Even Pros Make

• Overmixing the batter can lead to a dense cake. Mix just until combined.
• Not letting the butter and sour cream reach room temperature can affect the texture of the cake.
• Skipping the cooling step before glazing can cause the glaze to melt into the cake.
• Using stale or expired baking powder and soda may prevent the cake from rising properly.

Cooling, Storing & Rewarming

To cool the Espresso Crumb Coffee Cake, let it rest in the pan for about 10 minutes before transferring it to a cooling rack. This will help maintain its structure. Store any leftovers in an airtight container at room temperature for up to 3 days. If you prefer to keep it longer, consider refrigerating it for up to a week. To rewarm, simply place a slice in the microwave for about 10-15 seconds or enjoy it at room temperature.

Absolutely! Decaffeinated espresso powder will work perfectly in this recipe, allowing you to enjoy the flavor without the caffeine kick.

What if I don’t have sour cream on hand?

You can substitute the sour cream with Greek yogurt or buttermilk for a similar texture and moisture level.

Can I freeze the Espresso Crumb Coffee Cake?

Yes, this cake freezes well! Wrap individual slices tightly in plastic wrap and place them in an airtight container before freezing. They can be thawed at room temperature when you’re ready to enjoy.

How can I make this cake gluten-free?
