The Best Vegan Lemon Cake
Vegan Lemon Cake
Sunshine-bright lemon cake soaked in tangy syrup and finished with glossy glaze — fully vegan, one bowl, about 50 minutes
This vegan lemon cake is pure sunshine. A tender, golden crumb gets poked full of holes while warm and flooded with tangy lemon syrup, then finished with a glossy glaze and fresh lemon slices.
One bowl, about 50 minutes, and zero eggs or dairy. Triple-lemon — cake, syrup, glaze — means every bite tastes like the brightest part of the week.
Why you'll love this lemon cake
- Triple lemon — zest in the cake, syrup soak, glossy glaze
- 100% vegan with zero specialty ingredients
- One bowl, about 50 minutes, pantry staples
- Impossibly moist from the warm syrup soak
- Stays fresh for days — the syrup keeps it tender
- Showstopper looks with fresh lemon slices on top
Health notes
- Lemon: Vitamin C in every layer — juice, zest and syrup.
- Oat milk: Keeps the crumb tender and dairy-free.
- Applesauce: Replaces eggs while adding fiber and keeping fat down.
- Olive oil: A modest amount gives richness without butter.
- Portion reality: This is a treat — bright, but still cake.
Key element — poke and soak while warm
The lemon syrup must go onto a warm cake. Poke deep holes with a skewer the moment it leaves the oven and pour the syrup over slowly — a warm crumb drinks it up; a cold crumb lets it pool on top.
Ingredients
Dry
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 2 tsp baking powder
- ½ tsp baking soda
- ½ tsp salt
- Zest of 2 lemons
Wet
- 1 cup oat milk (or any dairy-free milk)
- ⅓ cup olive oil (or neutral oil)
- ¼ cup fresh lemon juice
- ¼ cup unsweetened applesauce
- 1 tsp vanilla extract
Lemon syrup soak
- ⅓ cup fresh lemon juice
- ¼ cup granulated sugar
Glaze & topping
- 1 cup powdered sugar
- 2–3 Tbsp fresh lemon juice
- Thin lemon slices, for decorating
Swaps
- Gluten-free: A 1:1 gluten-free flour blend works — check doneness 5 minutes early.
- Lime: Swap every lemon for lime — same method, new citrus.
- Oil: Melted coconut oil or any neutral oil replaces olive oil.
- Sugar: Coconut sugar works but bakes up a darker, caramel-toned crumb.
Instructions
| 1 | Heat and prep. Preheat the oven to 350°F. Line a 9x5-inch loaf pan (or 8-inch square pan) with parchment, leaving overhang for lifting. |
| 2 | Whisk the dry. In a large bowl, whisk the flour, sugar, baking powder, baking soda, salt and lemon zest. Rub the zest into the sugar with your fingertips first — it releases the oils and perfumes the whole cake. |
| 3 | Whisk the wet and combine. In a second bowl, whisk the oat milk, olive oil, lemon juice, applesauce and vanilla. Pour into the dry and stir until just combined — a few small lumps are fine. |
| 4 | Bake. Pour into the prepared pan and bake 32–38 minutes, until golden and a toothpick comes out with a few moist crumbs. While it bakes, warm the syrup ingredients in a small pan until the sugar dissolves. |
| 5 | Poke and soak. While the cake is still warm, poke deep holes all over with a skewer. Pour the warm lemon syrup slowly over the top, letting it sink in. Cool completely in the pan. |
| 6 | Glaze and decorate. Whisk the powdered sugar with lemon juice to a thick but pourable glaze. Drizzle over the cool cake, arrange thin lemon slices on top, and let the glaze set 15 minutes before slicing. |
Pro tips
- Zest the lemons before juicing them — you'll need both, in that order.
- Don't overmix; stir just until the flour disappears for a tender crumb.
- Warm cake + warm syrup = maximum soak. Cold cake repels it.
- Glaze only when fully cool, or it melts into a puddle.
- Slice with a serrated knife using a gentle sawing motion — the syrup-soaked crumb is delicate.
