The Bread is in the Baking

I came home from work today and I was craving something sweet, but being low on money I could only use supplies I had in my kitchen and the only oil I have in my kitchen right now is olive oil. I'd seen some cake recipes floating around the interwebs with olive oil in them instead of vegetable oil or butter and was interested in giving one of them a whirl.
This one was the only one that fit my parameters exactly and it came out really great (so great, I'm pretty sure I've eaten half of the cake by myself...). This cake is dense and silky with wonderful flavor and the glaze really helps bring out more of the flavor.

Lemon Olive Oil Cake
3/4 cup olive oil (don't feel the need to use really fancy olive oil, I got mine from Trader Joes)
1 large lemon
1 cup all-purpose flour
5 egg yolks
4 egg whites
3/4 cup plus 1 1/2 tablespoons sugar
1 cup powdered sugar

Preheat oven to 350 degrees F. Grease an 8 inch springform, or 9 x 5 inch loaf pan with olive oil and line with parchment paper. Grease the parchment paper and then dust with flour.

Grate the lemon zest from the lemon and mix together with the flour in a medium bowl. Juice the lemon.

Quickly beat together the egg yolks and 1/2 cup sugar for about 3 minutes and then slowly beat in the olive oil and 1 1/2 tablespoons of lemon juice. Add the flour mixture and fold in gently with a wooden spoon or spatula.

  Using a mixer, beat 4 egg whites high speed with the whisk attachment until foamy. Continue to beat on high, slowly adding 1/4 cup of sugar until soft peaks form. Fold the egg whites into the cake batter until just combined. Pour into the prepared baking pan and sprinkle with the remaining sugar.

Bake until a toothpick inserted into the center comes out clean, about 45 minutes. Cool for 10 minutes in the pan, then remove to a wire rack to cool completely.

Prepare the glaze by whisking together the powdered sugar 1 tablespoon of the fresh lemon juice. Add more lemon juice if necessary to get the desired consistency and pour over the cooled cake.
