- 1 1/2 teaspoons baking powder
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened

(Note: Full ingredient measurements are provided in the recipe card below.)
Instructions
Step 1: Preheat Your Oven and Prepare the Pan
- Preheat your oven to 325°F (163°C).
- Grease and flour a 9×5-inch loaf pan or bundt pan. This will ensure your cake slides out smoothly after baking.
Step 2: Mix the Dry Ingredients
- In a medium-sized bowl, whisk together 2 1/2 cups of all-purpose flour, 1 1/2 teaspoons of baking powder, and 1/4 teaspoon of salt. Set aside.
Step 3: Cream the Butter and Sugar
- In a large bowl, use an electric mixer to cream together the softened 1/2 cup of butter and 1 1/4 cups of granulated sugar until light and fluffy, about 3-4 minutes.
Step 4: Add the Eggs and Wet Ingredients
- Beat in the 4 large eggs, one at a time, ensuring each egg is fully incorporated before adding the next.
- Mix in the 1 tablespoon of lime zest and 1/4 cup of key lime juice until combined.
- Add 1 teaspoon of vanilla extract and mix well.
Step 5: Combine Dry Ingredients with Wet Ingredients
- Gradually add the dry flour mixture to the wet ingredients, alternating with the 1/2 cup of whole milk. Start and end with the flour mixture. Mix until just combined. Be careful not to overmix, or the cake may become dense.
Step 6: Bake the Cake
- Pour the batter into the prepared loaf or bundt pan and smooth the top.
- Bake in the preheated oven for 50-60 minutes (for a loaf pan) or 40-50 minutes (for a bundt pan), or until a toothpick inserted into the center comes out clean.
Step 7: Cool the Cake
- Allow the cake to cool in the pan for about 10 minutes. Then, turn it out onto a wire rack to cool completely.
Step 8: Make the Key Lime Glaze
- While the cake cools, whisk together 1 cup of powdered sugar and 2-3 tablespoons of fresh key lime juice until smooth. Adjust the consistency by adding more juice if you prefer a thinner glaze or more powdered sugar for a thicker glaze.
- Optionally, stir in 1 teaspoon of lime zest for an extra pop of lime flavor.
Step 9: Glaze the Cake
- Once the cake has cooled completely, drizzle the key lime glaze over the top of the cake, allowing it to drip down the sides.
