Ingredients
Gathering your ingredients is step one to deliciousness! Here’s what you’ll need:
- ½ cup (8 tablespoons | 4 oz | 113 g) unsalted butter, room temperature: Make sure your butter is softened – it makes creaming so much easier and gives you a better texture.
- Zest from 1 large lemon: Don’t skip this! It adds a little burst of sunshine that pairs beautifully with blueberries.
- 1 cup (214 g) sugar: Most of this goes into the batter, but you’ll save a little bit for sprinkling on top for that lovely crisp crust.
- 1 egg, room temperature: Like the butter, a room temperature egg incorporates into the batter much more smoothly.
- 1 tsp. vanilla extract: Just a touch enhances all the other flavors.
- 2 cups (256 g) all-purpose flour: Standard all-purpose is perfect here. We’ll use a little bit to coat the blueberries, which helps prevent them from sinking.
- 2 tsp. baking powder: This is our leavening agent, helping the cake rise and become light and fluffy.
- 1 tsp. kosher salt: Balances the sweetness and brings out the flavors.
- 2 cups fresh blueberries, picked over: Look for plump, firm berries. Give them a quick rinse and pat them dry before using.
- ½ cup buttermilk: This is the secret ingredient for moisture and tenderness! If you don’t have buttermilk, I’ve got a tip for you below.
How to Make It
Alright, let’s get baking! It’s truly simple, I promise.
First things first, let’s get the oven ready. Preheat your oven to 350ºF (175ºC). While it’s heating up, grease your baking pan. An 8- or 9-inch square pan works great. You can use butter or non-stick spray. Sometimes, I like to line the bottom with a piece of parchment paper after greasing – it makes getting the cake out super easy, especially if you want to lift the whole thing out to slice.
Now, grab your mixer, either a stand mixer or a hand-held one. We’re going to cream the softened butter with the lemon zest and almost all of the sugar (remember to save that 1 tablespoon for the top!). Beat this mixture until it looks light and fluffy, scraping down the sides of the bowl as needed. This usually takes a few minutes.
Next, add that room temperature egg and the vanilla extract. Beat until everything is just combined. Don’t overmix here.
In a separate, medium-sized bowl, gently toss your fresh blueberries with about ¼ cup of the all-purpose flour. This little trick helps the blueberries stay suspended in the batter instead of all sinking to the bottom while baking.
In yet another bowl (I know, bowls!), whisk together the rest of the flour, the baking powder, and the salt. Give it a good whisk to make sure the baking powder and salt are evenly distributed.
Now it’s time to combine the wet and dry ingredients. Add about half of the flour mixture to your butter/sugar/egg mixture. Use a spatula to gently stir it in until it’s mostly incorporated. Don’t worry about getting every single lump out just yet.
Pour in all of that lovely buttermilk and stir it in until it’s combined with the batter.
Add the remaining flour mixture and stir until the flour is just absorbed. Again, be careful not to overmix. A few small lumps are totally fine! Overmixing can lead to a tough cake.
Finally, the star of the show – the blueberries! Gently fold the floured blueberries into the batter using your spatula. Try to leave behind any excess flour that might be left in the bottom of the blueberry bowl.
Spread the batter evenly into your prepared baking pan. Get it into the corners and make the top as smooth as you can.
Remember that tablespoon of sugar you saved? Sprinkle it evenly over the top of the batter. This creates a delightful, slightly crunchy crust.
Pop the pan into your preheated oven. Bake for 35 to 45 minutes. You’ll know it’s done when a toothpick inserted into the center comes out clean or with just a few moist crumbs attached. If the top starts getting too brown before the center is cooked, you can loosely tent it with foil.
Once it’s out of the oven, let it cool in the pan for at least 15 minutes before slicing and serving. It’s best served warm!
Substitutions & Additions
This recipe is wonderful as is, but feel free to play around and make it your own!
- No Buttermilk? No Problem! You can make a quick substitute. For ½ cup, measure ½ cup of regular milk (dairy or non-dairy) and stir in 1 ½ teaspoons of white vinegar or lemon juice. Let it sit for 5-10 minutes until it looks slightly thickened and curdled. Use that mixture in place of the buttermilk.
- Other Berries: Fresh raspberries, blackberries, or a mix of berries would also be delicious. If using frozen, don’t thaw them. You may need to add a few extra minutes to the baking time.
- Different Citrus: Not a lemon fan? Try orange zest instead!
- Add Nuts: A sprinkle of chopped walnuts or pecans over the top with the sugar would add a lovely crunch.
- Streusel Topping: Instead of just sugar, you could make a simple streusel topping (flour, sugar, butter, maybe some cinnamon) and sprinkle that over the batter before baking.
- A Simple Glaze: Once the cake is cool, you could whisk together powdered sugar with a little milk or lemon juice and drizzle it over the top.
Tips for Success
Here are a few little pointers to help ensure your cake turns out perfectly every time:
- Use Room Temperature Ingredients: I mentioned it for the butter and egg, but it really makes a difference in how smoothly your batter comes together.
- Don’t Overmix: Once you add the flour, mix just until it’s combined. Overmixing develops the gluten too much, which can result in a tough cake.
- Toss Blueberries in Flour: This step is key to preventing all your lovely berries from sinking to the bottom of the pan.
- Check for Doneness: Use the toothpick test! Ovens vary, so rely on the toothpick rather than just the timer.
- Cool Before Cutting: Letting the cake cool in the pan for 15 minutes allows it to set up properly. Cutting into a hot cake can make it crumbly.
- Prep Ahead: You can whisk together the dry ingredients the night before. Just store them in a covered bowl.
How to Store It
This cake is best enjoyed warm, but leftovers are pretty great too!
Store any leftover cake in an airtight container at room temperature for 2-3 days. If it lasts that long!
For longer storage, you can refrigerate it for up to a week. Reheat individual slices gently in the microwave if you like them warm.
You can also freeze baked and cooled cake. Wrap individual slices or the whole cake tightly in plastic wrap, then wrap again in foil. It should keep in the freezer for up to 3 months. Thaw overnight in the refrigerator or at room temperature.
FAQs
Can I use frozen blueberries?
Yes, you can! Don’t thaw them before tossing them in flour and adding them to the batter. They might bleed a little color into the batter, but the cake will still be delicious. You might need to add a few extra minutes to the baking time.
Why do I need buttermilk?
Buttermilk is acidic, and when it reacts with the baking powder, it helps the cake rise beautifully. The acidity also helps break down gluten, resulting in a super tender, moist crumb. If you don’t have it, the quick substitute works well!
Can I make this cake in a different size pan?
You could likely make this in a 9-inch round cake pan, but the baking time might vary slightly. Just use the toothpick test to check for doneness. A loaf pan might be too deep unless you adjust the quantity or increase the baking time significantly.
Is this cake very sweet?
No, it’s sweet enough to feel like a treat but not overly sugary, making it perfect for breakfast or brunch. The tartness of the blueberries and the hint of lemon balance the sweetness nicely.
