Lemon Blueberry Cupcakes with Zucchini

filed under: Cupcakes on July 23, 2015

I shared a recipe for Blueberry Zucchini Cake and it has been popular to say the least! One question that people ask over and over is, “Can I make this into a cupcake?”

Yes! Yes, you can. But I do have a few tips on how to make it the perfect cupcake.

I decreased the number of blueberries from the original recipe. With a smaller amount being used, you are able to taste the light, sweet cake. The smaller amount also means that the blueberry compliments the cupcake instead of overwhelming it.

I decreased the amount of buttercream significantly. I highly recommend a small amount of frosting on these cupcakes. The lemon buttercream works amazingly well with the blueberry zucchini cupcake, but if you have a large amount of frosting it tends to overpower the cupcake.

Do not overbake the cupcakes! Mine were done at about 17 minutes at 350 in a convection oven. The moment that the center no longer appears “wet” is when they are done.

I prefer to not peel the zucchini prior to grating as I love to see the green flecks. But this is simply a preference and you can certainly peel yours. Be warned though, people will not be able to tell that the cupcakes contain a healthy vegetable!

These cupcakes also taste delicious without frosting. In fact, you would almost think it’s a muffin with the light crumb and blueberries! But the amount of sugar and oil really does not qualify these as a muffin. Then again, they are probably better for you than a donut!

Just a quick shout out… thanks to all those that have supported me this blog and through social media. It means a great deal to me and I feel humbled and grateful for you. Thank you!

    Can the zucchini blueberry cupcakes be made with less sugar?

  • Janet says:

    I make these as mini cupcakes. I don’t feel so guilty about eating them then. They go a long way at work as well. I have given out this recipe over and over again. These are simply the best!

  • Bree Cramer says:

    I make this cake every summer. It’s a moist flavorful cake with a light and fluffy icing! The lemon juice really lightens up the icing. I do add the zest called for in the icing recipe to the cake so I don’t lose the lemon flavor but keep my icing piping bag friendly.
    This year I made a blue hydrangea bush!

    Recipe is a delicious and I will be trying it because I love blueberries and cream cheese together with puff pastry

  • Noreids says:

    I made your recipe and the cupcakes came out dry. I followed your instructions to a tee. What would happen if I put the zucchini in without squeezing some juice out?

    • Amanda Rettke says:

      SO sorry! You can definitely use UNdrained zucchini.

  • Debra bachmeier says:
