How to Make Buttery Coffee Cake
Make the Crumb Topping: In a medium bowl, mix together 1 2/3 cup all-purpose flour, 1/4 cup cornstarch, 1/2 cup light brown sugar, 1/2 cup granulated sugar, and 1 tsp ground cinnamon. If using unsalted butter, add a pinch of kosher salt. Pour in 3/4 cup melted salted Kerrygold butter, stirring until everything is evenly combined and resembles thick, clumpy crumbs. Place the bowl in the refrigerator while preparing the cake batter.
Prepare the Cake Batter: Preheat your oven to 350°F and grease and line an 8×8 pan with parchment paper, allowing the paper to reach over the sides for easy removal later. In a large mixing bowl, use a fork to mash together 1/4 cup room-temperature salted Kerrygold butter, 2 tbsp oil, and 1/2 cup granulated sugar until mixed. Switch to a whisk and blend until creamy and light in color.
Add Egg and Vanilla: Whisk in 1 large egg and 1 egg yolk, 1 tbsp vanilla extract (or vanilla bean paste), and 1/2 cup sour cream until smooth. Next, whisk in 1/4 tsp baking soda, 1/4 tsp baking powder, and 1/4 tsp kosher salt to ensure even distribution. Finally, mix in 1 cup all-purpose flour until you achieve a creamy cake batter.
Layer the Cake: Spread the batter evenly into the prepared pan. Remove the crumb topping from the refrigerator— it should be solid enough to break into fine crumbs. Sprinkle a generous layer of crumbs over the cake batter to ensure each bite is filled with delicious crumble!
Bake: Place the pan in the preheated oven and bake for about 30 to 35 minutes. The cake should have a slight rise, and its center shouldn’t wobble when nudged. A toothpick inserted into the middle should come out clean with maybe a few crumbs attached.
Cool and Serve: Let the cake cool for about an hour in the pan before carefully removing it with the parchment paper. Dust the top with powdered sugar, slice it up, and enjoy this delightful treat!
Storing & Reheating
To store your Buttery Coffee Cake, keep it at room temperature in an airtight container for up to 3 days. For longer storage, wrap it tightly in plastic wrap and refrigerate, where it’ll stay fresh for up to a week. You can also freeze slices for up to 3 months. To reheat, simply warm individual pieces in the microwave for 10-15 seconds or in a toaster oven until just warmed through. The texture will change slightly, so a light dusting of powdered sugar will refresh its appearance!
Chef’s Helpful Tips
- Avoid overmixing the cake batter; this will help maintain its light texture.
- For even better flavor, let the butter sit briefly at room temperature before mixing with sugars.
- Be patient while the cake cools; this will allow it to set properly and make cutting simpler.
- Feel free to add chopped nuts or swirls of cinnamon sugar to the crumble for an extra flavor boost!
- This cake can be made ahead of time and stored, making it a great option for busy mornings.
Buttery Coffee Cake is such a delightful, timeless dessert that brings a smile with every bite. Its warmth and goodness are perfect not just for gatherings but for a little self-love too. So why not take a break, savor the moment, and indulge in a slice (or two)? Your taste buds will thank you, and your home will fill with the inviting scent of baked bliss!

Recipe FAQs
Can I make Buttery Coffee Cake ahead of time?
Absolutely! You can prepare the cake batter and the crumble topping the night before. Just store them separately in the refrigerator. When you’re ready to bake, proceed with assembling the cake and bake it fresh in the morning for a delightful breakfast treat!
Can I use unsalted butter instead of salted?
Yes, you can! If you choose to use unsalted butter, simply increase the kosher salt to 1/2 tsp in the recipe. This adjustment will ensure that the flavors are balanced.
How should I store leftover coffee cake?
Store your leftover coffee cake in an airtight container at room temperature for up to 3 days. If you’d like to keep it longer, wrap it well in plastic and freeze it for up to 3 months, ensuring you keep the freshness intact!
What can I do if my crumb topping gets too wet?
If your crumb topping feels too wet or clumpy, you can add a little more flour to the mixture to achieve the desired crumbly texture. It should hold together but break apart easily when sprinkled over the batter. Adjust to your preference, and don’t hesitate to make it your own!
