As Kim notes,you don't need to use a specialty olive oil for this cake. But if you have one with a lot of flavor, the cake will be that much better. This is one of those recipes where I think using regular sugar is the way to go. There was plenty going on with the interplay between the rosemary, chocolate, and olive oil - and I'm not sure adding less refined brown or Muscovado sugar would have been the way to go. The last note I'll make is to suggest chopping up a chocolate bar for this. It's just not going to be the same if you use uniform chocolate chips. Aim for big chunks 1/2-inch in diameter, you'll end up with all sorts of shavings and littler pieces as you are chopping, and having that mix of flecks and the big chunks is pretty great.
Olive oil for the pan
Dry ingredients:
3/4 cup / 3 oz / 80g spelt flour or whole wheat pastry flour
1 1/2 cups / 7.5 oz / 210 g all-purpose flour
3/4 cup / 4 oz / 115g sugar
1 1/2 teaspoons baking powder
3/4 teaspoon kosher saltWet ingredients:
3 eggs
1 cup / 240 ml olive oil
3/4 cup / 180 ml whole milk1 1/2 tablespoons fresh rosemary, finely chopped
5 ounces / 140 g bittersweet chocolate (70% cacao), chopped into 1/2-inch pieces
2 tablespoons sugar for top crunch
Preheat the oven to 350F / 175C. Rub a 9 1/2-inch (24 cm) fluted tart pan, or equivalent, with olive oil (and/or line with parchment paper).
Sift the dry ingredients into a large bowl, pouring any bits of grain or other ingredients left in the sifter back into the bowl. Set aside.
In another large bowl, whisk the eggs thoroughly. Add the olive oil, milk and rosemary and whisk again. Using a spatula, fold the wet ingredients into the dry, gently mixing just until combined. Stir in 2/3 of the chocolate. Pour the batter into the pan, spreading it evenly and smoothing the top. Sprinkle with the remaining chocolate and run a fork along the length of the chocolate so that the batter envelops it just a bit. Sprinkle with the second sugar.
Bake for about 40 minutes, or until the top is domed, golden brown, and a skewer inserted into the center comes out clean. My cake, in the alternate pan, took closer to 50 minutes. Also, just when my cake was nearly finished baking, I decided I wanted a bit more color on top. I finished it under the broiler for a minute - which caramelized the sugar on top as well and gave it a bit of crunch. Don't walk away from the cake while it is under the broiler.
The cake can be eaten warm or cool from the pan, or cooled, wrapped tightly in plastic, and kept for 2 days.
Serves 8 -12.
