Gluten-free lemon and poppy seed cake with ricotta icing

Gluten free lemon and poppy seed cake

This is a very moist gluten-free cake. It is zingy and delicious without being too sweet. And who knew you could bake with mashed potatoes.



125g sugar

125ml olive oil

4 eggs

175g ground almonds

250g mash potato

3 lemons zested

2tbs poppy seeds

2tsp baking powder

Pinch of salt

3 drops of Young Living essential lemon oil (optional)


You could use the cream cheese frosting from the Carrot and courgette muffins

Or you could make a Ricotta cheese frosting

200g firm ricotta

1-2 tbsp of honey or maple suryp

1 tsp lemon zest


  1. Heat oven to 180C. Butter and line a, 20cm bread tin. Beat the sugar and olive oil together until light and fluffy, then gradually add the egg, beating after each addition. Fold in the almonds, cold mashed potato, lemon zest, poppy seeds, baking powder, salt, and lemon essential oil if you are using it. It is totally optional but it adds even more lemon flavour.
  2. Tip into the tin, level the top, then bake for 30-40 minutes or until golden and a skewer inserted into the middle of the cake comes out clean. Turn out onto a wire rack after 10 mins cooling. Let the cake cool completely before icing.

Frosting method

Meanwhile, while the cake is cooking make the icing, whisk the ricotta, honey, lemon zest and vanilla in a stand mixer fitted with the whisk attachment until combined. Add 2 tbs water and continue whisking until smooth. Let the cake cool down completely and use a spatula to spread the ricotta icing on top of the cake. Sprinkle with lemon zest and poppy seeds.


Make sure to mash the potatoes well and get all the lumps out. I have even pushed the mash through a sieve on a few occasions. 

This recipe could also be baked in a round tin but it is a very flat cake.
