Carrot and Zucchini Olive Oil Cake (Gluten Free)

Carrot and Zucchini Olive Oil Cake - easy gluten free dessert! by Lisa Lin of

Baking, for me, is often an exercise in restraint: How much sugar can I really put in these muffins before it’s too much? How much chocolate can I mix into these cookies and still get away with calling them “healthy”? My week-long struggle with this carrot and zucchini cake tested those boundaries. Five baking sessions later, we have a loaf cake that is just right, just sweet enough.

First confession: I desperately wanted to give this thing a meyer lemon glaze. Those orangey-yellow citrus orbs are in peak form right now, and a nice shot of the meyer lemon glaze drizzling down on the cake would have been epic food porn. Then, I took a step back and asked myself, does this bread really need more sugar? I think you know the answer. This cake was great just the way it is with maple syrup and a shredded fuji apple as the primary source of sugar. You see . . . exercise in restraint. Don’t worry, the meyer lemon did come into play with this recipe. Inside one of these slices are tiny flecks of lemon zest, which brightens up the flavor of the cake.

Second confession: I added carrots and zucchini to this cake mainly to trick the hubs into eating more vegetables. I’ve been doing that to smoothies with great success, so I figured I could push my luck with cake, too. And he fell for it. Mission accomplished.

  • Getting the Right Amount of Sweetness: I tried so many different combinations of sweeteners for this recipe. First, I started with honey/muscovado/grated pear, then I tried honey/muscovado/applesauce, and finally settled on maple syrup/grated apple. The versions with applesauce were my least favorite—the cake tasted bland compared to the other loaves I made with grated fruit. I quite enjoyed the honey/muscovado/grated pear, but for the sake of simplicity, I stuck with maple syrup/grated apple.
  • Texture of the Cake: Because this cake is made with gluten-free flours, it will be more crumbly than those made with all-purpose or other wheat flours. It cut nicely into 1/2-inch slices, but the cake gets quite messy when you’re trying to cut them into smaller pieces for sharing.

  • Total Time: 1 hour 10 minutes
  • Yield: 12
  • Category: gluten free, dessert, breakfast


  • 2 large eggs
  • 1/4 cup (60ml) olive oil
  • 2/3 cup (155ml) maple syrup
  • 1 tsp vanilla extract
  • 1 1/3 cups (180g) gluten-free all-purpose flour*
  • 1/4 cup (30g) millet flour
  • 1/4 cup (35g) oat flour**
  • 1 1/2 tsp ground cinnamon
  • 1/4 tsp freshly grated nutmeg
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 cup (105g) grated carrots
  • 3/4 cup (95g) grated zucchini
  • 1 medium fuji apple (about 85g), peeled and grated
  • zest of one lemon

Optional Toppings

  • shredded coconut
  • black sesame seeds


  1. Preheat oven to 350 degrees F (175 degrees C). Position an oven rack to the middle position.
  2. In a large bowl, whisk eggs together. Stir in olive oil, maple syrup and vanilla extract. In another bowl, mix flours, cinnamon, nutmeg, baking powder, baking soda, and salt. Pour flour mixture into bowl of wet ingredients and stir until everything is just combined. Let batter rest for 5 to 10 minutes.
  3. Spray a 9×5-inch loaf pan with cooking spray. I like adding a small sheet of parchment on top so that the bread is easier to release later. I usually spray the parchment with oil lightly. Set aside.
  4. Fold in grated carrots, zucchini, apple, and lemon zest to batter. Pour batter into prepared loaf pan. Sprinkle shredded coconut and sesame seeds on top, if you like.
  5. Bake for 45 to 55 minutes, rotating halfway. A toothpick inserted down the center should come out clean. Let cake cool in pan for 10 minutes before removing it and cooling on a rack. Let cool for at least 45 minutes to an hour before cutting into it.


1. *You can always use all-purpose flour or store-bought gluten-free flour for this recipe. I used the gluten-free blend in America’s Test Kitchen’s How Can it be Gluten Free, and I omitted the non-fat milk powder. [br][br]2. **You can use 1/2 cup of oat flour instead of 1/4 cup millet flour and 1/4 cup oat flour. I thought the texture of the millet and oat flour blend was slightly better.

      Hi Gayle, thanks for your message. You’re not missing anything—I didn’t put it into the recipe! This cake calls for 1/4 cup olive oil. I’ve updated the recipe to reflect this. Thank you so much!

    Hooray YOU – five times is epic, but I get it! Sometimes it’s just necessary to get it just the way you want it. Indeed, food porn would be good with the glaze… but I know this is amazing without. Love how you packed all those veggies in this Lisa and to trick the hubs is brilliant! I’m constantly working on the same battle over here! And green smoothies are a great way to do it! Dates are my trick! Such a fabulous loaf my dear! ox
