Ingredients
For the Cake:
- 1½ cups all-purpose flour – I always use unbleached for a slightly richer flavor.
- 1 tsp baking powder – Make sure it’s fresh for the best rise.
- ½ tsp baking soda – Another key to a light and fluffy cake!
- ¼ tsp salt – Enhances all the other flavors.
- ½ cup (1 stick) unsalted butter, softened – Room temperature is crucial for easy creaming.
- 1 cup granulated sugar – Sweetness and moisture for the perfect texture.
- 2 large eggs – Bind the ingredients and add richness.
- 1 tsp vanilla extract – A touch of classic flavor.
- 1 cup buttermilk – Adds tang and moisture; you can make your own by adding 1 tablespoon of lemon juice or vinegar to 1 cup of milk.
- 1 cup fresh or frozen blueberries – Fresh are best if you have them, but frozen work perfectly too!
For the Lemon Cream Cheese Frosting:
- 8 oz cream cheese, softened – Again, room temperature is key for a smooth frosting.
- ½ cup (1 stick) unsalted butter, softened – Adds richness and creaminess.
- 3 cups powdered sugar – The sweetness that balances the tartness of the lemon.
- 2 tbsp lemon juice – Adds that bright, zesty flavor.
- 1 tsp lemon zest – For an extra burst of lemon flavor and aroma – don’t skip this!
How to Make It
Making the Cake:
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. This prevents sticking and ensures easy removal.
- Whisk together the flour, baking powder, baking soda, and salt in a medium bowl. This is a great step to get the kids involved!
- In a large bowl, cream together the softened butter and sugar until light and fluffy. I use my stand mixer for this, but a hand mixer works just as well.
- Beat in the eggs one at a time, then stir in the vanilla. Scrape down the sides of the bowl to make sure everything is well combined.
- In a separate bowl, gently whisk together the buttermilk and blueberries. Be gentle to avoid smashing the blueberries.
- Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk mixture, beginning and ending with dry ingredients. Mix until just combined. Don’t overmix!
- Pour the batter into the prepared pan and spread evenly.
- Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. Every oven is different, so keep an eye on it!
- Let cool completely before frosting.
Making the Frosting:
- Beat together the softened cream cheese and butter until smooth and creamy. This is where my stand mixer really shines!
- Gradually add the powdered sugar, beating until light and fluffy. Add it slowly to avoid a sugar cloud!
- Stir in the lemon juice and lemon zest. The zest adds a lovely pop of flavor and aroma.
- Frost the cooled cake evenly. Get creative with your frosting technique!

Substitutions & Additions
Feel free to get creative! Swap the blueberries for raspberries, blackberries, or even chopped strawberries. For a richer cake, use whole milk instead of buttermilk. If you don’t have lemon, you can use orange zest and juice instead for a completely different flavor profile!
Tips for Success
- Don’t overmix the batter. Overmixing develops gluten, resulting in a tough cake.
- Make sure your butter and cream cheese are softened to room temperature for the best texture.
- Let the cake cool completely before frosting; otherwise, the frosting will melt.
- Prep ahead: Make the cake a day in advance and frost it right before serving.
How to Store It
Store leftover cake in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. The frosting might firm up in the fridge, but it’ll still be delicious!
FAQs
- Can I use frozen blueberries? Yes! Just make sure they’re thawed before adding them to the batter.
- What if my cake is dry? Next time, make sure your baking powder and soda are fresh, and don’t overbake the cake.
- Can I make the frosting ahead of time? Yes, you can make the frosting a day or two in advance and store it in an airtight container in the refrigerator. Let it come to room temperature before frosting the cake.
- Can I use a different size pan? You can adjust the baking time accordingly if you use a different size pan, but a 9×13 inch is ideal for this recipe.
