  • 3 Cups (375 grams) Cake Flour
  • ½ tsp Baking Soda
  • ¼ tsp Kosher Salt
  • 1 Cup (16 Tbsp) Unsalted Butter softened
  • 2 Cups (400 grams) Granulated Sugar
  • 1 Cup (240 grams) Coconut Oil melted, then cooled to room temperature
  • 5 Large Eggs
  • 2 tsp Vanilla Extract
  • 1 Cup (240 grams) Whole Milk
  • ⅓ Cup (80 grams) Blue Chair Key Lime Rum Cream
  • 2 Tbsp Key Lime Zest

Key Lime Icing

  • 2 Cups Powdered Sugar
  • 2 Tbsp Blue Chair Key Lime Rum Cream
  • 1 tsp Lime Juice
  • 1 tsp Milk as needed

Instructions

Cake Batter

  • Prepare a bundt cake pan with baking spray and preheat oven to 325 F (170 C).
  • In a large bowl, hand whisk together sifted cake flour, salt and baking soda. Set aside.
  • Combine sugar and butter in the bowl of a stand mixer fitted with paddle attachment. Beat on medium high speed until combined into a light and fluffy consistency.
  • Add coconut oil and mix on medium until incorporated. Scrape sides and bottom of bowl with rubber spatula once to make sure all ingredients are mixed in.
  • Continue on medium speed, adding one egg at a time. Make sure each egg is blended before adding the next.
  • Next, slowly pour milk and spoon in flour mixture alternating between the two while mixing on medium low speed.
  • Scrape sides and bottom of mixing bowl once.
  • On medium low speed pour in Key Lime Rum Cream and add lime zest. Mix until just incorporated.
  • Batter should be light and fluffy.
  • Spoon into prepared bundt pan leaving about 1 ¼ inches below the rim for cake to rise. (If you have extra batter, make a few cupcakes!)
  • Place bundt pan on a cookie sheet and bake on middle rack for 75-80 minutes or until toothpick inserted comes out with just crumbs.
  • Place cake pan on cooling rack to completely cool before inverting onto serving dish.
  • While cake is cooling make key lime icing.

Key Lime Rum Frosting

  • Make your frosting by starting with two cups of powdered sugar, then add the lime juice and rum cream.
  • Stir together in a bowl, slowly adding a little milk as needed to create the consistency you like best. If you want it thicker add more powdered sugar.
  • Drizzle over cake before serving.
