Pro Tips and Variations
- Use room‑temperature butter, cream cheese, eggs, and buttermilk for a smoother batter and frosting and more even baking.
- Don’t overmix once the flour is added; mix just until combined to avoid a tough cake.
- If your blueberries are very juicy or large, you can lightly dust them with flour instead of powdered sugar to help prevent sinking.
Variations:
- Swap some blueberries for raspberries for a lemon‑berry layer cake variation.
- Add a thin layer of lemon curd between the cake layers under the frosting for extra citrus intensity.
- Bake the batter in a Bundt pan and glaze with a simple lemon icing for a more casual presentation.
Storage and Make-Ahead
- Store the frosted cake covered in the refrigerator (because of the cream cheese frosting) for up to about 3–4 days. Let slices sit at room temperature briefly before serving for best texture.
- You can bake the lemon blueberry layers a day in advance, wrap them well once completely cool, and frost the next day.
- The layers also freeze well when tightly wrapped; thaw in the fridge, then frost.
FAQ
Can I use frozen blueberries?
Yes, many lemon blueberry cakes use frozen blueberries; add them straight from frozen and fold gently, noting they may streak the batter slightly more than fresh.
Can I make cupcakes with this batter?
This style of lemon blueberry cake batter can typically be portioned into cupcake tins; bake at 350°F and start checking around 18–22 minutes.
Why is buttermilk important?
Buttermilk’s acidity reacts with baking soda and baking powder to help the cake rise and also tenderizes the crumb, resulting in a moist, soft texture.
Is the frosting very sweet?
The cream cheese and lemon juice cut through the sweetness of the powdered sugar, giving a balanced, tangy‑sweet frosting that complements the cake.
Can I reduce the sugar?
Slight reductions are possible, but cutting sugar too much can affect texture and moisture; for a lighter feel, use a thinner layer of frosting or serve with lightly sweetened whipped cream instead.
