- 1 cup granulated sugar
- ½ cup unsalted butter, softened
- 2 large eggs
- 1 teaspoon vanilla extract
- ½ cup buttermilk
- Zest of 1 lemon
- 2 tablespoons fresh lemon juice

Substitutions for Key Ingredients
You can swap some ingredients if needed:

- Buttermilk: Mix ½ cup milk with ½ tablespoon lemon juice or vinegar for a quick substitute.
- Blueberries: If you cannot find fresh blueberries, use frozen ones. Just make sure they are thawed and drained.
These options keep the cake delicious while catering to your pantry.
Fresh vs. Frozen Blueberries
Fresh blueberries have a bright taste and firm texture. They give the cake a burst of flavor. However, frozen blueberries are also a great choice. They are picked at peak ripeness and frozen quickly. This preserves their flavor.
When using frozen blueberries, remember:
- They may release more juice while baking.
- Gently fold them into the batter to prevent breaking.
Both fresh and frozen blueberries work well, so choose what you have!
Step-by-Step Instructions
Preparation and Mixing the Batter
Start by preheating your oven to 350°F (175°C). Next, grease and flour a 9-inch square baking pan. In a large bowl, mix ½ cup of softened butter with 1 cup of granulated sugar. Beat them together until light and fluffy. It’s like magic!
Now, add 2 large eggs one at a time. Mix well after each addition. Then, stir in 1 teaspoon of vanilla extract, the zest of 1 lemon, and 2 tablespoons of fresh lemon juice. Keep mixing until it’s smooth.
In another bowl, whisk together 1 ½ cups of all-purpose flour, 2 teaspoons of baking powder, ½ teaspoon of baking soda, and ¼ teaspoon of salt. Gradually add this dry mix to the wet ingredients. Alternate with ½ cup of buttermilk. Mix it until just combined. Be gentle!
Finally, fold in 1 cup of fresh blueberries. Take care not to break the berries. Pour the batter into your prepared pan and spread it evenly.
Making the Crumb Topping
For the crumb topping, grab a small bowl. Mix ½ cup of brown sugar, ½ cup of rolled oats, and ½ teaspoon of ground cinnamon. Add about 2 tablespoons of flour to this mix.
Now, use your fingers to mix in the remaining ½ cup of softened butter. Keep mixing until it looks like coarse crumbs. This will give your cake a lovely crunch!
Baking and Cooling Instructions
Sprinkle the crumb topping generously over the batter in the pan. Place it in the preheated oven and bake for 45-50 minutes. Check it by inserting a toothpick in the center. It should come out clean.
Once done, let the cake cool in the pan for at least 10 minutes. After that, transfer it to a wire rack to cool completely. Enjoy the fresh and flavorful treat!
Tips & Tricks
How to Achieve the Perfect Crumb Texture
To get a light and crumbly topping, mix the dry ingredients well. Use cold butter when making the crumb topping. It helps form that nice, crunchy texture. Make sure to break the butter into small pieces. This way, it blends well with the sugar and oats. Don't over-mix your batter either. Mix just until you see no flour. This keeps the cake light and fluffy.
Common Mistakes to Avoid
One common mistake is over-mixing the batter. If you mix too much, the cake can turn out tough. Another mistake is using old baking powder or baking soda. Always check your leavening agents for freshness. Also, be careful with the blueberries. If you crush them while mixing, the cake can turn blue. Gently fold them in to keep their shape and flavor.
Serving Suggestions and Presentation Tips
For a beautiful presentation, slice the cake and dust it with powdered sugar. Add a few fresh blueberries on the side. It adds color and makes it look fancy. You can also serve it with a scoop of vanilla ice cream for a special touch. This cake pairs well with tea or coffee, making it a great treat for gatherings.
Pro Tips
- Choose the Right Blueberries: Fresh blueberries yield the best flavor and texture. If using frozen, ensure they are thoroughly thawed and drained to prevent excess moisture in the cake.
- Perfect Crumb Topping: For a crunchier topping, consider adding chopped nuts like pecans or walnuts to the crumb mixture.
- Check for Doneness: Since ovens vary, start checking your cake a few minutes before the suggested baking time. A toothpick should come out clean or with only a few moist crumbs.
- Storage Tips: Store any leftover cake in an airtight container at room temperature for up to 2 days, or refrigerate for longer freshness.
Variations
Alternate Flavors and Additions
You can change the flavors in this cake easily. Try using raspberries or strawberries instead of blueberries. These berries add a different taste while keeping it fresh. For a twist, add a teaspoon of almond extract. This gives a nice depth to the lemon flavor. You can also mix in some nuts for crunch. Chopped walnuts or pecans work well here.
Gluten-Free Adaptations
Making this cake gluten-free is simple. Replace the all-purpose flour with a gluten-free blend. Many blends work well in baking. Just check that it has xanthan gum for better texture. You may need to adjust the baking time slightly. Start checking for doneness a few minutes earlier.
Make it Vegan: Substitutions
To make this cake vegan, swap the eggs for flax eggs. Mix 1 tablespoon of flaxseed meal with 2.5 tablespoons of water. Let this sit for five minutes to thicken. Use plant-based butter instead of regular butter. You can also replace buttermilk with almond milk mixed with a bit of lemon juice. This gives the same tangy flavor without any dairy.
