Preheat the oven to 350 F Grease a 6 inch round pan with oil and place a parchment paper at the bottom of the pan. In a mixing bowl crack the eggs and add the sugar. Whisk to mix it smooth. Then pour the oil, milk, and orange zest. Mix it again.

Place a sifter on top of the bowl and to that add the flour, corn meal, baking powder, baking soda and salt. Sift the dry ingredients to the wet ingredients and mix it lightly to incorporate everything.

Pour the batter to the prepared baking pan and place it in the middle rack. Bake for 35 to 40 minutes.

While the cake bakes prepare the orange syrup. In a bowl add the sugar, water and the orange juice. Bring it boil then simmer in medium heat for 10 minutes.

Once the cake is ready, take it out of the oven. Once it’s cooled down a bit, take the cake out of the oven and poke it all around using a toothpick. Pour the syrup on top and allow the cake to soak up the syrup. Let the cake cool down completely before you layer the frosting.

To prepare the frosting, whisk the butter using a stand mixer until it’s fluffy. Then add the powdered sugar, milk, salt and orange zest. Whisk again to combine everything. Slice the cake in half, and layer the frosting evenly. Garnish the cake with orange slices.
