Step 1

If frozen, defrost phyllo.

Step 2

Preheat the oven to 350 degrees F and brush a 9 x 13-inch baking pan with a little oil or butter.

Step 3

For the cake, put the eggs, vegetable oil, and sugar in a large bowl. Beat the mixture well with an electric mixer until the ingredients are well combined. Add the yogurt, orange zest, baking powder, and vanilla. Beat to combine.

Step 4

Cut phyllo into long, thin ribbons. Add phyllo ribbons to the cake batter and stir it in with a spatula. Evenly spread the batter in the prepared pan.

Step 5

Bake the cake for 45 to 55 minutes, until a knife inserted into the center comes out clean.

Step 6

Make the syrup while the cake is baking. In a medium saucepan, stir together the orange peel, water, and sugar. Bring the mixture to a boil then simmer it over medium heat for 20 minutes, until it thickens to the consistency of maple syrup, stirring often. Let the syrup cool.

Step 7

When the cake comes out of the oven, pour the syrup on top. Allow cake to cool and absorb all the syrup.

Step 8

Slice and serve!
