A bright, sunshine-flavored Vegan Lemon Loaf Cake — almond-flour base, applesauce instead of eggs, maple-syrup sweetness, and a powdered-sugar lemon glaze that turns this simple loaf into a real dessert.

Perfect for plant-based households, allergy-friendly gatherings, or anyone who wants a lighter alternative to traditional baked goods.

Ingredients

Loaf

  • 3–4 Tbsp lemon zest (about 3 large lemons)
  • 4 Tbsp lemon juice
  • ½ cup unsweetened applesauce
  • ¼ cup avocado oil
  • ½ cup maple syrup
  • 1 Tbsp vanilla extract
  • 2 cups almond flour
  • ¾ cup potato starch
  • ⅓ cup cornstarch
  • 2 tsp baking powder
  • 1 tsp sea salt

Glaze

  • 1½ tsp lemon zest
  • ½ tsp vanilla extract
  • 3 Tbsp lemon juice
  • 1¼ cup powdered sugar, sifted

Instructions

  1. Preheat oven to 350°F and line or oil your loaf pan.
  1. In a large mixing bowl, add lemon zest, lemon juice, applesauce, avocado oil, maple syrup, and vanilla extract — whisk to combine.
  1. Add almond flour, potato starch, cornstarch, baking powder, and sea salt and whisk again until no lumps remain. It should be pretty thick.
  1. Pour the batter into the prepared loaf pan. Smooth the top with a spatula.
  1. Bake for 50–60 minutes until a toothpick inserted into the center comes out clean.
  1. While the cake cools, make the glaze in a clean mixing bowl.
  1. Zest the lemon and set aside. Whisk together the vanilla extract and lemon juice, then begin slowly adding sifted powdered sugar — mixing until smooth.
  1. Once all the powdered sugar is added, add the zest and mix once more.
  1. Pour the glaze over the cooled cake and let it set for a few minutes before slicing.

Why This Recipe Works

Almond flour + starches — the combination produces a tender, slightly dense crumb that's structurally satisfying without being heavy. Almond flour brings moisture and richness; the starches give the structure.

Applesauce instead of eggs — provides moisture and binding without dairy or eggs. The flavor is neutral enough that the lemon shines through.

Maple syrup instead of sugar — adds a subtle layer of caramelized depth and pairs beautifully with the lemon.

Avocado oil — neutral, healthy fat that doesn't compete with the lemon flavor (unlike coconut oil, which would).

Tips for Best Results

  • Use fresh lemons — bottled juice and zest don't have the brightness fresh lemons bring. This recipe is all about the lemon, so the lemon has to be good.
  • Don't skip the sift — sifting the powdered sugar for the glaze prevents lumps and produces a clean, glossy finish.
  • Let it cool fully before glazing — pouring glaze on a warm cake will cause it to run off and pool at the bottom of the plate. Patience.
  • Storage — keeps for 3 days at room temperature in an airtight container, 5 days refrigerated, or up to 3 months frozen (wrap individual slices).

Variations

  • Add poppy seeds — 2 Tbsp for classic lemon-poppyseed
  • Add lavender — 1 tsp culinary lavender steeped in the lemon juice first
  • Berry topping — top each slice with macerated berries and a touch of coconut whipped cream

When to Make It

  • Holiday season — when most baked goods are heavy and chocolate-forward, this is a bright counterpoint
  • Brunch hosting — pairs perfectly with morning coffee or tea
  • Gift-giving — wraps cleanly, holds up to transport, looks beautiful with the glaze on top
  • Anytime someone in your circle has dietary restrictions — vegan, dairy-free, egg-free, and easy to make gluten-free by sourcing certified GF starches
