  4.9 – 8 reviews  • Squash

These muffins are incredible. I created this recipe because I couldn’t find any good squash muffins. These cannot be kept on the table.

Yield: 1 15-1/2×10-1/2-inch sheet cake

Ingredients

  1. 2 cups white sugar
  2. 2 cups shredded zucchini
  3. 1 cup vegetable oil
  4. 3 large eggs
  5. 2 ½ cups all-purpose flour
  6. 1 teaspoon baking soda
  7. ¼ teaspoon baking powder
  8. ¼ teaspoon salt
  9. ¼ cup lemon juice
  10. 1 tablespoon lemon extract
  11. 1 (8 ounce) package cream cheese, softened
  12. ½ cup unsalted butter, softened
  13. 1 teaspoon lemon extract
  14. 4 ½ cups powdered sugar

Instructions

  1. Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 15-1/2×10-1/2-inch sheet cake pan.
  2. Mix sugar, zucchini, oil, and eggs together in a large bowl with an electric mixer. Combine flour, baking soda, baking powder, and salt in another bowl. Add dry ingredients to sugar mixture and combine; don’t overbeat. Mix in lemon juice and lemon extract. Pour into the prepared pan.
  3. Bake in the preheated oven until golden brown and a toothpick inserted into the center comes out clean, 30 to 40 minutes. Remove from the oven and let cool completely, 20 to 30 minutes.
  4. Meanwhile, beat cream cheese and butter for frosting together in a bowl. Beat in lemon extract, then gradually beat in powdered sugar. Frost cooled cake.
  5. You can use vanilla extract instead of lemon extract in the frosting.
  6. I baked mine for 38 minutes and it was perfect!

This is a fabulous cake even when used yellow summer squash and not zucchini. Definitely will make this often.

My husband said this was the best cake I’ve ever made, so that was a ringing endorsement because I’ve made a few. I didn’t have lemon extract so I added extra zest. We don’t like lots of frosting so I made just enough for a glaze-like topping. The cake was gone in a couple of days and I’ve been asked to bake another soon.

Need to make adjustments for high altitude.

Excellent cake for Easter dinner! I had to make it in a Bundt cake pan since I made it during the Corona Pandemic and had limited refrigerator space for a sheet pan. The change worked perfectly and I had to bake it an additional 5 minutes. I frosted it with the yummy frosting, but only needed half of it.

Made no changes in the original recipe. Next time might add a tad more lemon extract or even some lemon zest.

Amazing. I would decrease the powdered sugar in the frosting to 4 cups. Kind of sweet. The card was moist and delicious!! Will bd one of my favorites.

Loved this cake! I have been a chocolate fanatic all my life. Lately I have been wanting something different. Saw this recipe, and because it had zucchini I wanted to try it. It is so goooood! I made no changes. Although I only made half the icing with 1 tsp lemon extract. I don’t like a lot of icing if it is sweet. This amount of icing was perfect for us. THANK YOU FOR THE RECIPE, WE LOVE IT!

Woohoo, I’m first. I made the cake exactly as per the recipe and my family was blown away. One person said it had the lovely flavor of lemon fruit loops:-) Super moist, soft and slightly crispy around the edges, just fantastic. I chose not to frost it, just a sprinkle of icing sugar.
