Sweet, tart, and full of lemon flavor, this vegan lemon poppyseed snack cake is easy and delicious! Gluten-free.
Sometimes a simple snack cake is all you really need.
Most often made with minimal ingredients, low-pressure frosting, and no layers with which to contend.
Plus, no serious prep time called for either.
Sounds pretty good, right?
On this Mother's Day weekend, I've got a vegan lemon poppyseed cake for you. It fits all the criteria above and is full of that bright, tart, and sweet lemon flavor you love.
Vegan Lemon Poppyseed Cake Ingredients
The cake base tastes like a lemon-flavored sugar cookie. Topped with a dairy-free lemon buttercream, you'll be going back for seconds immediately.
Here's the major ingredients you'll need:
- almond flour
- coconut flour
- organic cane sugar
- agave syrup (or honey if not vegan)
- vegan butter
- organic powdered sugar
Almond flour and coconut flour combined make for a protein and fiber rich cake, while keeping it grain-free as well. A little extra goodness in your cake never hurt, I'd say.
Making Vegan Gluten-Free Snack Cake
A couple tips for making this lemon snack cake:
Due to the egg-free nature of this gluten-free vegan cake, you want to make sure the cake is completely cool before frosting. It can be delicate, so apply a thick layer of frosting on top before spreading it into an even layer.
I like grating a little extra lemon zest on top for some pretty natural "sprinkles." However you decorate it, it's a cake recipe that works for casual outdoor gatherings or more celebratory ones.
