  • 1 1/4 cups bleached all-purpose flour

  • 1 1/4 cups bleached all-purpose flour

  • One 10-inch spring form pan, buttered and lined with a disk of parchment or wax paper

Method

  • Set a rack at the middle level of the oven and preheat to 350 degrees.
  • For the cake batter, in a large mixing bowl, cream the butter until soft and light.
  • Use a hand mixer set at medium speed or a heavy-duty mixer fitted with the paddle, if you have one.
  • Gradually beat in the sugar and continue beating for about 5 minutes, until very light.
  • Add the egg and continue beating until lighter.
  • Add the yolks, one at a time, beating after each addition and scraping the bowl and the paddle occasionally.
  • Beat in the lemon zest and vanilla.
  • Sift the flour and baking powder together several times, then stir into the batter.
  • To make the topping, mix the flour, sugar, and cinnamon in a bowl.
  • Melt the butter and stir it in evenly.
  • Rub the mixture to coarse crumbs by hand.
  • Rinse, halve, and pit the apricots.
  • Spread the batter evenly in the prepared pan.
  • Arrange the apricot halves, leaving a margin of 1/2 inch around the edge, cut side up on the batter, but dont press them in.
  • Scatter the crumbs evenly over the apricots and the batter.
  • Bake the cake for 50 to 60 minutes, until the crumbs are well colored and the cake is firm and no longer liquid in the center.
  • Cool the cake in the pan, then run a knife around the edges to loosen it from the pan.
  • Remove pan side and slide from base to a platter.
  • Dust the cake lightly with the confectioners sugar.
