Step-by-Step Instructions for Key Lime Cake
1. Preparing the Cake Batter
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
- Add eggs one at a time, mixing well after each addition.
- In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
- Gradually add the dry ingredients to the wet mixture, alternating with buttermilk, beginning and ending with the dry ingredients.
- Mix in the key lime juice, zest, and vanilla extract until just combined. Be careful not to overmix, as this can result in a dense texture.
2. Baking the Cake Layers
- Divide the batter evenly between the prepared pans.
- Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
- Remove the cakes from the oven and allow them to cool in the pans for 10 minutes. Transfer to a wire cooling rack to cool completely before frosting.
3. Making the Key Lime Cream Cheese Frosting
- In a medium mixing bowl, beat the softened cream cheese and butter together until smooth and creamy.
- Gradually add the powdered sugar, one cup at a time, beating until fully incorporated.
- Mix in the key lime juice, vanilla extract, and lime zest. Continue beating until the frosting is fluffy and easy to spread.
4. Assembling and Frosting the Cake
- Place one layer of cake on a serving plate or cake stand.
- Spread a thick layer of frosting over the top.
- Add the second layer and frost the top and sides of the cake.
- Use a spatula to create swirls or patterns in the frosting. Garnish with extra lime zest or thin lime slices for a professional touch.
Tips for the Best Key Lime Cake
Creating a flawless key lime cake involves paying attention to the details. Here are some tips to ensure your cake comes out perfect every time:
- Don’t Overmix the Batter: Overmixing can cause the cake to become dense and heavy. Mix until ingredients are just combined.
- Use Fresh Key Lime Juice and Zest: Fresh ingredients make a significant difference in flavor. Avoid bottled key lime juice if possible.
- Properly Measure Flour: To prevent a dense texture, spoon flour into the measuring cup and level it off rather than scooping directly from the bag.
