Cooking Method for Lemon Blueberry Zucchini Cake

Creating the Lemon Blueberry Zucchini Cake is an enjoyable process that fills your kitchen with delicious aromas. Follow these steps closely, and you’ll have a beautiful cake ready for all to enjoy. Let’s get started!
Prep your pan. Preheat your oven to 350 degrees F. Grab an 8×8 inch square pan and line it with parchment paper. This ensures easy removal later.
Prep the zucchini. First, measure out 1 cup of shredded zucchini. Place the shredded zucchini in a paper towel or cheesecloth and squeeze out all of the moisture. This step is crucial; excess moisture can lead to a soggy cake.
Mix the wet ingredients. In a large bowl, add the drained zucchini, eggs, honey, lemon zest, lemon juice, and almond extract. Whisk them together until well combined, ensuring a smooth mixture.
Add dry ingredients. To the wet mixture, incorporate the almond flour, oat flour, baking soda, and salt. Mix it all together with a wooden spoon until everything is combined.
Add the blueberries. In a separate medium bowl, toss the fresh blueberries with 2 tablespoons of oat flour. This coating helps keep them from sinking to the bottom of the cake during baking. Gently fold the blueberries into the batter, being careful not to overmix.
Bake the cake. Pour the batter into the prepared pan, spreading it evenly. Bake in the preheated oven for 30 to 35 minutes or until a toothpick inserted into the center comes out clean. It’s tempting to check early, but patience here yields a perfect cake.
Cool the cake. Once baked, allow the cake to cool completely on a wire rack before frosting. This is crucial; if the cake is warm, the frosting will melt and create a gooey mess!
Make the frosting. For the frosting, beat together the softened butter, powdered sugar, lemon juice, and lemon zest in a bowl with a hand mixer until smooth and fluffy.
Frost the cake. Spread the lemon frosting evenly over the cooled cake. Garnish with extra blueberries on top for a vibrant finish.
Slice and enjoy! Cut the cake into 9 slices and serve. Each slice is a delightful treat for any occasion!
Things Worth Knowing
- Let the cake cool completely: It’s essential to wait for the cake to cool fully before frosting. This ensures that the frosting doesn’t melt off.
- Use fresh ingredients: Fresh blueberries and zucchini make a world of difference in flavor and moisture.
- Don’t skip the zest: The lemon zest adds a punch of flavor that enhances the overall taste of the cake.
- Check for doneness: Every oven is different, so keep an eye on your cake towards the end of the baking time for perfect results!

Ingredients
Equipment
Method
- Prep your pan. Preheat the oven to 350 degrees F. Line an 8x8 inch square pan with parchment paper and spray with nonstick cooking spray. Set aside.
- Prep the zucchini. First, measure out 1 cup of shredded zucchini, then place shredded zucchini in a paper towel or cheese cloth and squeeze out all of the moisture/water. This is very important!
- Mix the wet ingredients. Add shredded zucchini, eggs, honey, lemon zest, lemon juice and almond extract to a large bowl and whisk together until well combined.
- Add dry ingredients. Almond flour, oat flour, baking soda and salt. Mix together with a wooden spoon until well combined.
- Add the blueberries. In a separate medium bowl, toss blueberries together with 2 tablespoons of oat flour. (This is to prevent the blueberries from sinking to the bottom of the cake while baking.) Fold coated blueberries into the batter.
- Bake the cake. Pour batter into the prepared pan. Bake for 30-35 minutes or until a tester comes out clean. Allow the cake to cool completely on a wire rack before frosting. I know this is difficult but it’s critical (otherwise the frosting will melt and become a gooey mess!)
- Make the frosting. Beat together butter, powdered sugar, lemon juice and lemon zest together on high with a hand mixer or in the bowl of an electric mixer until smooth. Spread frosting over cooled cake. Garnish with a few blueberries. Cut into 9 slices and enjoy!
Notes
- Tip 1: I do not recommend a substitution for almond flour, as that’s the only ‘fat’ in this recipe and helps to keep the cake moist and retain its texture.
- Tip 2: If you’re looking for an oat flour sub, I think regular flour or GF 1:1 flour would work well, but haven’t tested it myself.
- Tip 3: Cake can be made a day ahead of time. After a day, the cake should be transferred and stored in the fridge.
