My vegan and gluten-free lemon poppy seed loaf cake is a summertime treat that you won't want to miss out on. The combination of tangy lemon, crunchy and earthy poppy seeds, and a creamy lemon frosting make this cake a treat that everyone will love!
Ingredients Needed
My vegan lemon poppy seed loaf recipe uses pantry staples that you probably already have on hand! Here's what you'll need:
- Plant-based Milk: We like to use a plant-based milk like unsweetened oat or almond milk!
- Vegan Butter: Vegan butter adds some moisture and creates a tender lemon poppy seed cake.
- Lemon Juice: We like to use fresh lemon juice for the best flavor, but bottled lemon juice will work in a pinch!
- Sugar: You can use regular cane sugar or try using our absolute favorite purecane sugar substitute!
- Lemon Extract: For extra lemon flavor, a bit of lemon extract does the trick. A little bit goes a long way!
- Baking Soda & Baking Powder: Baking soda and baking powder are added to help the cake rise in the oven.
- Vanilla Extract: For added flavor!
- Flour: We recommend using regular all-purpose flour or for a gluten-free lemon poppy seed loaf, use King Arthur Measure for Measure Gluten-free Flour!
- Poppy Seeds: Just one tablespoon of poppy seeds goes a long way. If you aren't a poppy seed fan, you can definitely omit them for a classic lemon loaf.
- Vegan Lemon Frosting: You can whip up your own vegan lemon frosting my combining lemon juice, powdered sugar and plant-based milk!
How to Make This Recipe
Step 1: Preheat the oven to 375 F.
Step 2: Mix the oat milk, melted vegan butter, lemon juice, purecane or sugar, baking soda, baking powder, and vanilla together. Add the lemon extract if desired. Then, add the flour and mix until a batter forms. Be careful not to over mix or the cake will be dense! Finally, fold in the poppy seeds.
Step 3: Transfer the batter into a greased 9x5 inch metal loaf pan and bak in the oven for about 40-45 minutes or until the loaf has risen completely and is golden. While the loaf is baking, use a whisk to mix the powdered sugar, lemon juice and oat milk together to make the frosting.
Step 4: Allow the cake to cool and then drizzle the frosting over the top. Enjoy!
Expert Tips
- Don't over mix! For a tender, moist lemon cake, it is important not to over mix the batter. Mix the ingredients until just combined and gently fold in the poppy seeds!
- Eat it for breakfast! Don't be scared of eating this cake for breakfast. It is perfect to have along side your morning cup of coffee or chai!
- Let the loaf cool before icing! The frosting is more of a glaze that will stick to the loaf better if it is room temperature. If the loaf is too warm, all that beautiful glaze might slide right off!
- Measure your flour correctly! Too much flour can result in a dry lemon poppy seed cake. Lightly spoon the flour into the measuring cup without packing it down or shaking the measuring cup. Then, use the straight side of a butter knife to level the flour off!
Frequently Asked Questions
How do I know if my lemon loaf is done?
The loaf is done when it is risen and golden brown on top. You can know for sure that the cake is done by sticking a toothpick into the top. If the toothpick comes out clean with just a few moist crumbs, then the vegan lemon poppy seed loaf is done! If the toothpick looks wet like there is still batter in the middle, then the cake needs more time in the oven.
What vegan milk do you recommend using?
One of my favorite plant-based milks right now is Almond Malk. It has only three ingredients so you know exactly what is in it with no added sugars!
What other lemon poppy seed recipes do you have?
So glad you asked. I am a huge fan of all things lemon poppy seed. You should definitely try our lemon poppy seed muffins and lemon poppy seed pancakes!
Storage Recommendations
- To store: Store any leftover lemon poppy seed cake in an airtight container at room temperature for up to 3 days. The cake can also be stored in the fridge for up to 5 days, but might dry out a little bit in the fridge!
- To freeze: You can freeze this loaf for later by allowing it to cool and wrapping it in plastic wrap and then foil. Freeze for up to 2 months. Thaw in the fridge prior to frosting and serving.

Hello! I’d love to make this for my husbands birthday cake in a couple of days! Could I double it and fit it in a Bundt loaf or do a bigger cake pan? Do you have any recommendations? Thank you! xx

Hi Sophia, this recipe turns out great in bundt cake form! If you double it, you may need a very large bundt cake pan or do 2 separate cake rounds. Can't wait to hear how he likes it!

Can I sub coconut milk for oat milk?
Jillian says
Hi Connie, coconut milk will be delicious in this. I'd recommend using the refrigerated kind rather than the full-fat canned kind.
