Ingredients and Substitutions

Labeled photo of the ingredients needed to make lemon cake from scratch.

Flour - I've tested the cake with regular all-purpose flour and King Arthur's Measure for Measure gluten-free flour blend. The GF cake was good but a bit more dense and not quite as tender.
Sugar - To make sure your sugar is vegan and not processed with bone char, look for organic cane sugar or a product specifically labeled as vegan. I'm currently using this sugar from Whole Foods.
Lemons - You'll need 3 large lemons for the zest. We're also adding fresh lemon juice, but only 3 Tbsp. Any more liquid than that and you run the risk of a gummy texture.
Oil - Oil is great for vegan cakes-or any cake, really-because it creates a moist and soft crumb. I like to use a light-tasting olive oil in this lemon cake because it enhances the pale yellow color provided by the lemon zest. Feel free to use a different oil, something neutral like grapeseed or avocado oil.
Non-dairy milk - Any unsweetened non-dairy milk you like is fine here, such as oat, soy, or almond. I used plain almond milk.
Non-dairy yogurt - I know plain dairy-free yogurt isn't always easy to find in stores, but this ingredient really does improve both the flavor and texture of the cake. It also allows us to reduce the amount of oil needed. I used homemade soy milk yogurt this time. Other varieties like cashew, coconut, or almond milk yogurt are also great. Sub mashed banana or applesauce if necessary.
Baking powder and soda - These leaveners help our eggless cake rise. Make sure they're fresh enough to be active.
Garnish & decoration - Keep things simple with non-dairy whipped cream-store-bought or homemade. I used my aquafaba whipped cream for the photos. You can also create a simple lemon glaze with 1 cup powdered sugar and 3-4 teaspoon fresh lemon juice. See the Variations section below for frosting ideas.

See the recipe card below for ingredient amounts and step-by-step instructions.

How to Make Vegan Lemon Cake

First, preheat the oven to 350°F (175°C). Prepare your cake pan by lightly oiling and dusting with flour. If desired, and for extra easy removal, line the pan with parchment.

Zest the lemons, and make sure you have a very full 2 Tablespoons. In a large mixing bowl, use a fork to mash the zest into the sugar.

Mixing wet and dry ingredients separately.

Add the remaining wet ingredients to the lemon-sugar mixture, and whisk until the sugar is dissolved. Sift the dry ingredients into a separate bowl.

Stirring together the wet and dry ingredients for cake bater.

Pour the dry ingredients into the mixing bowl, and stir just until there is no visible dry flour, careful not to overmix. It's fine if it looks slightly lumpy.

Thick lemon cake batter poured into prepared pan.

Transfer the batter to the pan, and bake in the center of the oven for about 40 minutes. The cake is done when a toothpick inserted in the center comes out clean. Also, use a finger to lightly press the center of the cake. If it bounces back, the cake is done.

Allow the cake to cool in the pan for 15 minutes. Carefully flip out onto a plate or board, then place top-side up on a cooling rack. Cool completely before garnishing and slicing.

Variations

Gluten-free: Use a gluten-free baking blend such as King Arthur's Measure for Measure. During recipe testing the gluten-free cake didn't rise quite as much and was slightly more dense, but still delicious!

Layer cake: Double (or triple) the ingredients, and pair it with this vegan vanilla frosting. To make lemon frosting, per ½ cup of vegan butter, add 2 teaspoons lemon zest (or ½-1 teaspoon lemon extract), and 2 tablespoons fresh lemon juice.

Lemon-cream cheese frosting: Use the frosting linked above (or any vanilla frosting you like), and replace ½ cup of the vegan butter with 8 oz. vegan cream cheese. I recommend either Tofutti brand or Kite Hill for frosting.

Equipment Used

Bowls, measuring cups and spoons: You'll need one large mixing bowl, one medium bowl, and the standard measuring cups and spoons.
Kitchen scale: A scale is the best way to ensure accuracy, but not a deal-breaker. See Tips below.
Sifter: Any fine mesh sieve is fine. Sifting the flour creates a tender, lighter texture.
Microplane: for zesting the lemons
Metal baking pan: Choose between an 8x8 square pan, 9-inch round cake pan, or 9x5 loaf pan. They all hold the same volume, though bake time is slightly longer for a loaf pan.
A cooling rack is also helpful.

Recipe FAQs

Can I make it in advance?

Yes, once the cake is completely cool, wrap well with plastic wrap. It's fine at room temperature or refrigerated. If cold, remove the cake from the fridge 2-3 hours before serving to allow it to warm to room temperature. Then glaze or frost, if desired.

How should I store leftover cake?

The cake keeps well covered at room temperature for up to 2 days, refrigerated for up to 5 days, or frozen for up to 2 months. Wrap it well to prevent freezer burn. Keep in mind that if a perishable topping like whipped cream is used, the cake should be kept refrigerated.

Helpful Tips

You can bake this cake in an 8-inch square pan, 9-inch round, or 9x5 loaf pan. For a loaf, increase bake time to around 50 min. I'm sure it will be great for cupcakes, too, I just haven't tried that yet. Bake time for cupcakes should be around 20 minutes. If you try cupcakes, let us know in the comments!
Don't skimp on the lemon zest! This is where ALL of the irresistible lemon flavor comes from.
Use a kitchen scale for the most dependable results. If you don't have one, be sure to whisk the flour very well before gently scooping up with a measuring cup, and leveling off the top.
Sift the flour, baking powder, and baking soda for the best texture.
Properly oil and flour the pan to avoid sticking. If preferred, you can also line the pan with parchment paper to ensure easy removal.
If you plan to garnish with vegan whipped cream wait until just before serving to avoid unwanted moisture seeping into the cake.
