This Vintage Key Lime Cake is a refreshing twist on a classic dessert. With its zesty lime flavor and tender crumb, it brings a burst of sunshine to your table, no matter the season.
Butter is the backbone of this cake, providing richness and a smooth texture. Granulated sugar sweetens and helps create a tender crumb. Eggs add structure and moisture, while all-purpose flour gives the cake its body. The star, key lime juice, infuses the cake with its distinctive tartness. Whole milk contributes to a creamy texture, and vanilla extract enhances the overall flavor profile. Baking powder and baking soda ensure the cake rises perfectly, and a pinch of salt balances the flavors. Lastly, lime zest adds a fragrant citrus aroma and extra zing.
This cake pairs beautifully with a dollop of whipped cream or a scoop of vanilla ice cream. For a tropical twist, serve with a side of fresh berries or mango slices. A sprinkle of extra lime zest on top adds a vibrant touch.
Start by preheating your oven to 350°F. Grease two 9-inch round cake pans thoroughly, so your cakes release easily after baking. In a large mixing bowl, cream together the softened butter and sugar until the mixture is light and fluffy. This usually takes about 3-4 minutes with an electric mixer.
Next, add the eggs one at a time, beating well after each addition. This step is crucial for a smooth batter. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. This dry blend will be added to the wet mixture gradually.
Now, it's time to combine everything. Add the dry ingredients to the butter mixture in three parts, alternating with the key lime juice and milk. Start and end with the dry ingredients, mixing until just combined after each addition to avoid overworking the batter.
Finally, stir in the vanilla extract and lime zest. Divide the batter evenly between the prepared cake pans. You'll want to smooth the tops with a spatula for even baking. Pop them in the oven and bake for 25-30 minutes. Check them with a toothpick — if it comes out clean, they're ready.
After baking, let the cakes cool in their pans for about 10 minutes. Then, transfer them to a wire rack to cool completely before you think about frosting or serving.
