Frequently Asked Questions

If you’re making the blueberry lemon cake for the first time, or your previous attempts didn’t turn out as expected, here are some common queries that might come in handy:

Q. Why did my blueberries sink to the bottom of the cake?

Blueberries are large and heavy; therefore, they sink to the bottom of the cake batter. Mix 1 tbsp of flour with the blueberries, and toss them till they are well-coated. Now, the blueberries will not sink to the bottom when you fold them in the batter. Also, the batter in this recipe is quite thick, which might help keep the blueberries afloat.

Q. Why does my cake become dense after baking?

Cakes tend to become dense if you don’t add ingredients according to the given proportions. Sometimes, adding too much flour can also mess up the cake. Also, over-beating the batter can cause the cake to become dense. So, mix the cake just to combine the ingredients, and use a scale to measure the ingredients to avoid it getting too thick or too soft.

Q. Can I use soy milk in place of whole milk?

Yes, if you are lactose intolerant or have milk sensitivity, you can use nut, soy, or non-dairy milk instead of whole milk.

Q. How can I store the blueberry lemon cake?

You can keep the cake at room temperature in an air-tight container for several days. You can also place it in the fridge for up to 5 days, but the cake will dry out and lose its flavor.

Tips and Tricks for Making Blueberry Lemon cake

Here are some tips and tricks to make the perfect blueberry lemon cake:

1. Coat the blueberries in a tsp of flour to avoid them from sinking to the bottom.

2. If you want to make the frosting extra rich, add cream cheese to the buttercream frosting.

3. Move the blueberries around in the batter to avoid them sticking together in clumps.

4. Cool the cake completely before frosting it with buttercream.
