Lemon Poppy Seed Layer Cake

Frosted Lemon Poppy Seed Layer Cake


2 ½ cups your favorite Gluten Free Flour blend (I used King Arthur’s whole grain blend)

2 tsp gluten free baking powder

1/2 tsp baking soda

1/2 tsp salt

½ cup Truvia

1/2 cup poppy seeds

2/3 cup extra light olive oil

2/3 cup Agave

½ cup “buttermilk” (I used soy milk mixed with 1/2 tbsp lemon juice)

1/2 cup freshly squeezed lemon juice (depending on size of lemons, you will need anywhere from 3 to 6 lemons; you really do want to use fresh lemons if at all possible for the best taste)

1/2 cup water

6 egg whites, at room temperature

1/2 tsp cream of tartar

Baking Instructions:

1. Preheat oven to 350 degrees. Prepare three 9 inch round cake pans for use. (I just line the pans with parchment paper.)

2. Mix the flour with baking powder, baking soda, and salt. Add the truvia and poppy seeds. Set aside.

3. Mix oil, Agave, buttermilk, lemon juice and water. Set aside.

4. In a large mixer, beat the egg whites with the cream of tartar with the whisk attachment until thick, white peaks form when you lift the whisk.

5. Mix the dry ingredients into the wet ingredients. Combine well until the dry ingredients are completely moistened.  Batter will be thick.

6. Gently fold the beaten egg whites into the batter, a little at at time, until all the egg whites are fully incorporated into the batter.

7. Evenly and equally spread batter into each of the three cake pans and bake for about 15 minutes until the cake layers are puffed, golden, and a toothpick inserted into the cake comes out clean. (Mine took 17 minutes.)

8. Cool on the cake layers in their pans until completely cool.

9. Frost the layers with the lemon frosting below, and store in the refrigerator until close to serving time. Let the cake come to room temperature before serving. Enjoy!

Lemon Frosting


1 cup sugar

8 tsp gluten free flour (I opted to use rice flour so the color would be white)

2 tbsp cornstarch

1/4 tsp salt

1/3 cup lemon juice (use fresh lemons if you can; depending on the size of the lemons you will need about 2 to 4 lemons)

2/3 cup milk

1 cup vegan olive oil butter (I used the Earth Balance version)

1 tsp vanilla

Cooking Instructions:

  1. Whisk together the sugar, flour, cornstarch and salt in a pan. Whisk in the “milk” until smooth.
  2. Over low heat, stir constantly until the mixture begins to boil and thicken. Depending on how shallow your pan is, this will probably take about 4 to 8 minutes.
  3. Once the mixture is thick, pour the mixture into a shallow glass container to cool. I find that a glass pie pan works very well. It usually takes an hour or more to fully cool.
  4. Once the mixture is cool, in a mixer, beat the vegan butter until light and fluffy, and then scrape down the sides of the butter.
  5. Add the cooled mixture with the vanilla and beat the frosting on a low speed to incorporate the mixture into the butter. It will look a bit curdled. Scrape down the sides.
  6. Increase the speed and beat until the mixture looks like a light and fluffy frosting. Its texture and taste will be similar to a whipped cream frosting.
  7. Use the frosting to frost between the cake layers and the outside and top of the cake. (This made enough frosting to generously frost a three layer cake.)
