  1. Preheat oven to 325 degrees F (165 degrees C). Grease and flour a 10 inch tube pan.
  2. Stir the flour and baking powder together in a mixing bowl.
  3. Cream the shortening with 1 cup butter and 2 cups sugar in a large mixing bowl until light colored and fluffy. Beat in the eggs, one at a time until mixture is light colored. Stir in 2 tablespoons rum, 2 teaspoons Key lime juice, Key lime zest, and vanilla extract until thoroughly blended. Stir in the flour mixture alternating with the milk. Pour the batter into the prepared pan.
  4. Bake in preheated oven until a toothpick inserted into the center comes out clean, about 90 minutes.
  5. Meanwhile, make the glaze by creaming 1/4 cup sugar with 1/4 cup butter in a small saucepan until light colored and fluffy. Stir in 2 tablespoons Key lime juice until evenly blended. Bring to a boil, stirring constantly. Remove from the heat and stir in 3 tablespoons rum.
  6. Cool the cake in its pan for 10 minutes. Turn out onto a wire rack or serving plate. While the cake is still warm, use a toothpick to prick the top in many places. Pour the glaze evenly over the top of the cake so it drizzles down all sides. Cool the cake completely before serving.

This cake is extremely moist! Took less than 90 minutes for me, maybe 70-75...I dyed it green for fun, it was a big hit!



This cake was okay. I made it the morning it was served to company at my house and the glaze had not soaked through to all the cake. The top half was moist but the bottom was dry. I would suggest either using a wooden spoon to make the holes instead of a toothpick or not serving to the next day. However, I noticed even though it was moist the next day the rum flavor seemed to disapate.
