Directions

1. Preheat the oven to 360°F. Grease a square baking pan and line the bottom with parchment paper.
2. In a bowl, mix the lemon zest and sugar with your fingertips until you get a granulated mixture and the zest's oils are released. Add eggs and beat very well until fluffy. Add the oil and water and stir well.
3. Gradually add the sifted flour and baking powder, oat flour, and poppy seeds. Mix gently.
4. Pour the batter in the pan, and bake for about 40 minutes (or until a toothpick inserted into the center comes out clean).
5. Remove the cake from the oven. Prepare the syrup by heating a saucepan with sugar and lemon juice until the sugar dissolves. Remove the cake from the pan, prick several times with a toothpick, and cover with the syrup.
