Irresistible Weekend Indulgence: My Go-To Buttermilk Coffee Cake Creation
Everyone in my circle asks for this recipe constantly. The buttermilk makes this cake super moist and that crunchy nut topping is truly something special. I often bring it to weekend get-togethers or wrap it up as thoughtful handmade presents. There's really nothing better than enjoying a piece with your first cup of joe in the morning.
The Magic Element In This Delightful Coffee Cake
Buttermilk turns out to be the game-changer here. It gives you that soft, tender texture while the walnut and cinnamon mix on top adds just the right crunch. I usually whip this up on lazy Sunday mornings but it works just as well for a midday snack. And guess what? You likely already have all the ingredients sitting in your pantry.
Ingredients List
- All-Purpose Flour: 2 cups; self-rising flour works too (just skip the baking powder).
- Brown Sugar: 1 cup, packed; gives the topping its deep flavor.
- White Sugar: 1 cup; for basic cake sweetness.
- Cinnamon: 1 tsp; brings that cozy spice note.
- Canola Oil: ½ cup; vegetable oil makes a fine substitute.
- Walnuts: ½ cup, finely chopped; they create that lovely topping texture.
- Buttermilk: 1 cup; the key to keeping everything soft.
- Egg: 1 large; let it reach room temp for better mixing.
- Baking Powder: 1 tsp; helps with rising (don't need it with self-rising flour).
- Baking Soda: ½ tsp; ensures proper puffiness.
Step By Step Instructions
- Create the Topping Mix
- Mix flour, brown sugar, white sugar, cinnamon, and oil in a bowl. Take out ¾ of this mixture and add the chopped walnuts to make your topping.
- Prepare Your Batter
- To what's left of your flour mixture, add baking powder and baking soda. Then mix in your buttermilk and egg, stirring just enough to combine. Don't go overboard with mixing.
- Put It All Together
- Get your 9-inch pan ready with a bit of grease. Pour in your batter and sprinkle all that nutty topping mix evenly across the surface.
- Into The Oven
- Get your oven hot at 350°F (175°C) and let your cake bake for about 35 minutes. Check if it's done by poking the middle with a toothpick – it should come out clean.
- Finish Up
- Let it sit for 5-10 minutes before cutting. It's great warm or cooled down with your favorite hot drink.

Interesting Tidbit About Coffee Cake
I'm always getting asked why there's no actual coffee in this recipe. The funny thing is, coffee cake earned its name simply because it pairs so perfectly with a cup of coffee. The sweet nuttiness works amazingly well with your morning brew or after-dinner coffee moment.
Custom Variations
I sometimes swap the walnuts for pecans or throw some fresh berries on top for a twist. My daughter can't get enough of it with almonds while my husband prefers it without any nuts at all. What I love most about this cake is how you can tweak it while still keeping that warm, comforting feeling we all crave.
Frequently Asked Questions
- → How do I keep the coffee cake fresh?
Store it in a sealed container and keep it at room temperature for up to three days. Pop it in the fridge, and it'll last up to a week. Just know the topping might lose some crunch over time.
- → Can I put this cake in the freezer?
Definitely! Wrap it up well using plastic, then add foil. Freeze it for as long as three months, and let it thaw overnight in the fridge before eating.
- → What's a good sub for buttermilk?
If you're out of buttermilk, mix a tablespoon of lemon juice or vinegar into a cup of regular milk. Let it rest for a few minutes and use it just like buttermilk.
- → Can I pick other nuts for topping?
Sure, swap the walnuts with pecans, almonds, or even hazelnuts. Just chop them small to make sure they mix well in the crumble.
- → Why isn't the cake turning out moist?
Overbaking is a common issue. Use a toothpick to test it at the shortest baking time. Also, don't pack your measuring cup with flour—scoop it into the cup lightly.
Conclusion
This easy coffee cake is made with buttermilk for softness and walnuts for a crunchy topping. A versatile pick for casual or special occasions.
