Pre-heat oven. Pre-heat the oven to 175 C | 350 F.
Prepare cake batter. Whisk together the eggs, lemon zest, coconut sugar and vanilla extract in a medium to large sized bowl. Next, whisk together the almond meal, baking powder and cardamon in a large bowl. Then add the wet mixture to the dry mixture, stirring until combined.
Bake cake. Pour the mixture into a greased and line square baking pan and decorate with the flaked almonds. Place into the oven for 35 minutes to cook or until an inserted skewer withdraws clean.
Serve. Allow to cool slightly in the baking pan before slicing. Serve warm or cold.
Notes
This recipe works best if you use room temperature eggs. The mixture will mix more evenly and you will get more volume.
