Ingredients
Gathering your ingredients is the first step to pure happiness! Here’s what you’ll need for this delightful cake:
- ½ cup (113 g) unsalted butter: Make sure this is nice and soft, at room temperature! Softened butter creams beautifully and makes for a tender cake.
- Zest from 1 large lemon: Don’t skip this! It adds such a lovely brightness that cuts through the sweetness and pairs perfectly with the blueberries.
- 1 cup (214 g) sugar: This sweetens our cake just right. We’ll save just a tablespoon for sprinkling on top for a little sparkly crust.
- 1 egg: Just one, also at room temperature! Room temperature eggs incorporate better into the batter.
- 1 tsp vanilla extract: A classic flavor enhancer! Use good quality vanilla for the best results.
- 2 cups (256 g) all-purpose flour: The structure of our cake. We’ll reserve ¼ cup of this for tossing with the blueberries.
- 2 tsp baking powder: This is our leavening agent, giving the cake its lovely rise and tender texture.
- 1 tsp kosher salt: Salt balances out the sweetness and brings out all the other flavors.
- 2 cups fresh blueberries: The stars of the show! Pick them over to remove any stems or mushy berries. Fresh are best here!
- ½ cup buttermilk: This is key to the cake’s incredible moisture and tender crumb. Its acidity reacts with the baking powder for extra lift.
How to Make It
Alright, let’s get baking! This recipe is super straightforward. Just follow these steps and you’ll have a gorgeous cake in no time.
Step 1: Get Started! First things first, let’s preheat your oven to 350ºF (175ºC). While it’s warming up, grease an 8 or 9-inch square baking pan. Butter or baking spray works perfectly here to make sure your beautiful cake doesn of stick!
Step 2: Cream the Wet Ingredients. In a large bowl, using an electric mixer (or some good old-fashioned elbow grease and a whisk!), cream together your softened butter, the bright lemon zest, and most of the sugar (that’s the full cup minus the one tablespoon we saved for later). Beat this until it’s light and fluffy, scraping down the sides of the bowl as needed. This should take a few minutes.
Step 3: Add the Egg and Vanilla. Once the butter and sugar mixture is light and airy, add in your room temperature egg and the vanilla extract. Beat them into the mixture until everything is just combined and looks smooth.
Step 4: Prep the Dry Ingredients. In a separate medium bowl, grab your beautiful fresh blueberries. Toss them gently with that reserved ¼ cup of all-purpose flour. This little trick helps prevent the blueberries from sinking to the bottom of your cake while it bakes! In another medium bowl, whisk together the remaining 1¾ cups of flour, the baking powder, and the kosher salt. Give it a good whisk to make sure everything is evenly distributed.
Step 5: Start Combining. Now we’ll start adding the dry and wet ingredients to the butter mixture. Add about half of the whisked flour mixture to your bowl and stir it in on low speed, or by hand with a spatula, just until it’s incorporated. Don’t overmix here!
Step 6: Add the Buttermilk. Pour in all of your buttermilk and stir it into the batter. It might look a little curdled or separated at this point, but don’t worry, that’s totally normal!
Step 7: Finish the Flour. Add the remaining half of the flour mixture to the batter. Stir just until the flour disappears and everything is combined. Again, be careful not to overmix! A few small lumps are okay.
Step 8: Fold in the Blueberries. Gently fold in those floured blueberries. Use a spatula and be careful not to crush them. Distribute them as evenly as you can throughout the batter.
Step 9: Bake! Pour the batter into your prepared baking pan and spread it out evenly. Now, remember that tablespoon of sugar we saved? Sprinkle it right over the top of the batter. This creates a lovely, slightly crisp, and sparkly crust as it bakes!
Step 10: The Waiting Game (and the best part!). Pop the pan into your preheated oven. Bake for 35 to 45 minutes. The time will vary depending on your oven, so start checking around 35 minutes. You’ll know it’s done when a toothpick inserted into the center of the cake comes out clean. The top should be golden brown and the cake should look set.
Step 11: Cool. Once it’s out of the oven, let the cake cool in the pan on a wire rack for at least 15 minutes before slicing into it. This lets the cake set up properly. It’s delicious warm, but letting it cool slightly makes it much easier to slice.
Substitutions & Additions
This cake is wonderful as is, but don’t be afraid to play around! Here are a few ideas:
- Berries: No blueberries? You can swap them out for other berries like raspberries or blackberries, or even a mix! Just make sure they’re relatively dry before tossing with flour.
- Dairy-Free: You might be able to use a plant-based butter substitute and a dairy-free buttermilk (made by mixing plant-based milk with a tablespoon of lemon juice or vinegar and letting it sit for 5-10 minutes). Results may vary slightly, but it’s worth a try!
- Extra Lemon: For an even brighter cake, you could add another teaspoon of lemon zest to the batter or even a tablespoon of fresh lemon juice along with the buttermilk.
- Add Nuts: A sprinkle of chopped walnuts or pecans folded into the batter or sprinkled on top with the sugar would add a lovely crunch.
Tips for Success
Baking should be fun, not stressful! Here are a few little tips I’ve learned along the way to help ensure your cake turns out perfectly every time:
- Room Temp is Key: Seriously, make sure your butter and egg are at room temperature. This helps them emulsify better with the sugar and liquids, leading to a smoother batter and a more tender cake.
- Measure Your Flour Correctly: Spoon the flour into your measuring cup and then level it off with a straight edge. Scooping directly from the bag can compact the flour, leading you to add too much, which results in a dry cake.
- Don’t Overmix! Once you add the flour, stir only until it’s just combined. Overmixing develops the gluten, which can make your cake tough. A few small lumps of flour are better than a tough cake.
- Flour Those Berries: That step isn’t just for show! Tossing the berries with flour helps them suspend in the batter as the cake bakes, instead of all sinking to the bottom.
- Check for Doneness: Ovens vary, so start checking with a toothpick around the 35-minute mark. If it comes out with wet batter, it needs more time. A few moist crumbs clinging to the toothpick are fine, but you don’t want wet batter.
How to Store It
This cake is definitely best enjoyed the day it’s baked, especially warm! However, if you have leftovers (a rare occurrence in my house!), store them at room temperature, loosely covered, for 1-2 days. For longer storage, you can wrap slices individually in plastic wrap and then place them in an airtight container or freezer bag. It will keep in the fridge for up to 4 days or in the freezer for up to 2-3 months. Thaw slices at room temperature or gently warm them up.
FAQs
Got questions? Here are a few common ones:
Q: Can I use frozen blueberries?
A: Yes, you can! Don’t thaw them. Toss them with the ¼ cup of flour exactly as you would fresh blueberries. You may need to add a few extra minutes to the baking time as frozen berries can lower the batter temperature.
Q: What if I don’t have buttermilk?
A: No problem! You can make a quick substitute. Measure ½ cup of milk (dairy or non-dairy) and stir in 1 tablespoon of white vinegar or lemon juice. Let it sit for 5-10 minutes until it looks slightly curdled. Use this mixture in place of the buttermilk.
Q: Can I make this cake ahead of time?
A: Absolutely! You can bake the cake a day in advance and store it, covered, at room temperature. It’s still delicious the next morning, especially when served with coffee or tea.
Q: How can I tell if my butter and egg are at room temperature?
A: Room temperature butter should be soft enough to easily indent with your finger but not melty or greasy. A room temperature egg won’t feel cold to the touch; you can place it in a bowl of warm water for 5-10 minutes to quickly bring it to temp if you forget!
