Instructions
  1. Preheat oven to 350 degrees F.
  2. Prepare 9 X 13" pan by spraying with non-stick spray
  3. Sift dry ingredients into a medium bowl.
  4. Transfer 1 TBS flour mix to a larger bowl and add fresh blueberries, tossing gently to coat with flour.
  5. Set remaining flour mixture and blueberries aside.
  6. Stir milk, sour cream, vanilla, lemon extract and lemon zest in a small bowl.
  7. In the bowl of stand mixer, cream butter and sugar until pale yellow and very fluffy, about 5 min.
  8. Beat in eggs, one at a time, until well combined.
  9. Mix in flour mixture alternately with milk mixture, starting and ending with flour.
  10. Stir until just combined.
  11. Gently fold in blueberries and pour into prepared baking pan. (I used glass, because it's such a pretty cake).
  12. Bake cake until toothpick inserted into center comes out clean -about 40 min.
  13. Cool in pan for about 10 minutes.
  14. When slightly cooled, poke about 16-20 evenly placed holes in the cake with the handle end of a wooded spoon. (I did these holes at what would be the middle of a serving piece)
  15. Spread on the Lemon Curd, which was prepared ahead, making sure the holes fill up with the curd.
  16. Cool completely.
  17. When ready to serve, Frost with Lemon Mascarpone Cream Frosting
  18. Lemon Curd:
  19. Melt butter in a medium saucepan over medium-low heat.
  20. Remove from heat and add the lemon juice and zest.
  21. Mix together the sugar, salt and cornstarch and add it to the pan.
  22. Whisk in the egg yolks until smooth and return to heat.
  23. Cook over medium-low heat for about 10 min until the mixture has thickened and coats the back of a spoon.
  24. Do not allow the mixture to boil.
  25. Allow to chill in refrigerator completely before using. (I made mine the day ahead).
  26. Reserve ⅔ cup of lemon curd for the Mascarpone Cream Frosting, before spreading on the cake.
  27. Lemon Mascarpone Cream Cheese Frosting:
  28. Beat the sugar and cream to soft peaks in the mixer.
  29. Combine the mascarpone cheese and the reserved ⅔ cup of lemon curd in a small bowl.
  30. Gently fold the mascarpone and lemon curd mixture into the whipped cream, taking your time - gently.
  31. Gently stir in lemon zest.
  32. Spread frosting gently over the cake which has already been covered with remaining lemon curd. There should only be a very thin layer of curd visible.
  33. Serve immediately and listen to the raves!
