Rum and Raisin Cake

This recipe requires a bundt pan. 

1. Preheat oven to 350 degrees Fahrenheit.
2. Grease and flour the bundt pan.
3. In a small bowl, whisk together milk, sour cream, and rum. Set aside.
4. In a medium bowl, whisk together cake flour, baking soda, baking powder, and salt. Set aside.
5. In the bowl of a stand mixer, cream together the butter and sugar.
6. Add the eggs and egg yolks one at a time and scrape the bowl after each addition.
7. Mix in the extracts.
8. Add ⅓ of the dry ingredients to the batter and mix just until combined. Add ½ of the milk/sour cream mixture and mix.
9. Add another ⅓ of the dry ingredients, mixing just until combined.
10. Add the last ½ of the milk/sour cream mixture and beat until just combined.
11. Add the final ⅓ of the dry ingredients and mix just until combined, scraping down the sides of the bowl.
12. With a rubber spatula, add half the raisins.
13. Pour the batter into the prepared bundt pan and bake in the middle third of the oven. Bake for 50 minutes or until a toothpick comes out clean from the middle.
14. Meanwhile, make the glaze. In a heavy saucepan, melt the butter and mix in the sugar until the sugar is fully dissolved. Remove from heat and add in the heavy cream, milk, and extracts. Set aside.
15. When the cake is baked, let cool for 15 minutes in the pan. After 15 minutes, turn out the cake and let cool completely on a wire rack.
16. Once the cake is completely cool, glaze the top of the cake evenly and then sprinkle the remaining raisins around the cake.
