Ingredients
1 cup butter for richness and tenderness
½ cup vegetable shortening for richness and tenderness
3 cups granulated sugar
6 large eggs
3 cups all-purpose flour
½ teaspoon baking powder
1/8 teaspoon salt
1 cup milk for moisture balance
1 teaspoon vanilla extract
¼ cup key lime juice for tangy flavor
1 teaspoon key lime zest
1 cup powdered sugar
2 tablespoons key lime juice for tangy flavor
½ teaspoon vanilla extract
Instructions
1-Step 1: Preheat and Prep Your Pan
Start by preheating your oven to 325°F (163°C). Grease and flour a 10-inch tube pan thoroughly. Use vegetable shortening, butter plus flour, or baking spray for easy release. A 10-inch tube pan holds all this batter perfectly. If switching to a Bundt pan, dont overfill to avoid spills.
2-Step 2: Cream the Fats and Sugar
Beat the 1 cup softened butter and ½ cup vegetable shortening at medium speed until light and creamy. Gradually add 3 cups granulated sugar, beating until fluffy. This builds the base for your moist key lime pound cake with tangy lime glaze.
3-Step 3: Add the Eggs
Add 6 large eggs one at a time, mixing well after each. This keeps the batter smooth and emulsified.
4-Step 4: Mix Dry Ingredients
In a bowl, combine 3 cups all-purpose flour, ½ teaspoon baking powder, and 1/8 teaspoon salt. Set aside.
5-Step 5: Alternate Wet and Dry
Add the flour mixture and 1 cup milk alternately to the butter mix, starting and ending with flour. Mix just until blended.
6-Step 6: Fold in Flavors
Stir in 1 teaspoon vanilla extract, ¼ cup key lime juice, and 1 teaspoon key lime zest. Pour into your prepared pan.
7-Step 7: Bake to Perfection
Bake for about 1 hour 15 to 20 minutes. A wooden pick in the center should come out clean. Tent with foil loosely after one hour if browning too fast.
8-Step 8: Cool Properly
Cool in the pan 10 minutes, then turn out onto a wire rack to cool fully.
9-Step 9: Make and Add Glaze
Whisk 1 cup powdered sugar, 2 tablespoons key lime juice, and ½ teaspoon vanilla extract. Drizzle over the cooled key lime cake.
