  1. I made this cake yesterday. It was the first cake I ever made. With a few adjustments for altitude, it came out perfect! It is an absolutely delicious cake.

    • Hi Gayle, You could definitely use Huckleberries! They are often sweeter than blueberries, so cut back on the amount of sugar in the batter just a tad!

  2. Hey!
    I really would like to bake this awesone looking cake.
    But I need some help…
    I´m from Germany and I need to know what are 2,10″ in cm?
    I can´t find anything about it…

    Thank you 🙂

  3. If I don’t have lemon extract, can I use lemon juice instead??
    If so what will the amount be in teaspoons?
    Awaiting your reply.

  4. This looks fantastic! I will be making this very soon. Can you use freshly squeezed lemon juice instead of pure lemon extract? If so, would the amount stay the same?

  5. Question!! I live in Palestine and I can’t find fresh blueberries, can I use the blueberry filling pie? that comes in a can instead of fresh blueberries???

    • Hi Summer, Yes you could try using blueberry pie filling. If you can find frozen blueberries in the frozen section, that would be even better!

  6. You made your cake with three layers in the picture shown above, but the recipe only makes two layers. Does the ingredients change by only making two layers?

    • Hi, it depends on what size baking pan you are using. Sometimes I use 8″ pan instead of a 9″ pan to create a more narrow but taller cake with more layers. The ingredients stay the same.

  7. I am very pregnant and due any day but promised the family I would make this cake for Easter. I am considering baking the cakes and making the frosting so anyone can assemble and it will stay fresh longer. Do you think it will stay better unassembled or fine if I just refrigerate it for a few days all together? I was thinking I would wrap each layer in plastic wrap and refrigerate frosting. Any thoughts?

    • Hi! Sorry for the late response, I have not been checking my blog’s comments in a while. I hope the cake turned out great and I hope your pregnancy went well! All the best!
