Key Lime Cake
Ingredients
Method
1. Prepare the Cake Batter
Start by heating your oven to 175°C (350°F). Prep three 8-inch pans—grease, flour, and line the bottoms. In a large bowl, mix flour, sugar, baking powder, baking soda, and salt. Add butter gradually, mixing until the texture turns crumbly (think soft sand). Stir in oil and lime zest. In another bowl, combine lime juice and milk, then whisk in eggs and vanilla. Slowly pour this into the dry mix while stirring until smooth. Don’t rush—smooth batter = soft cake.
2. Bake the Layers
Divide batter evenly into pans. Bake for about 26–28 minutes.
Quick check: insert a toothpick—if it comes out clean or with a few crumbs, you’re good.
Cool cakes briefly in pans, then transfer to a rack to cool fully.
3. Make the Lime Curd
Whisk egg yolks, lime juice, sugar, and salt in a saucepan. Add butter and cook on low heat, stirring constantly until thick.
Important: Don’t stop whisking or it might scramble.
Strain for a silky finish, then chill.
4. Whip Up the Frosting
Beat butter and cream cheese until smooth. Add powdered sugar gradually. Mix in a few spoonfuls of the cooled curd for extra zing. Adjust sweetness if needed.
5. Assemble the Cake
Level your cake layers if needed. Spread frosting between each layer. Want extra flavor? Add a thin layer of curd between layers—game changer. Cover the entire cake with frosting. Press graham crumbs around the base. Add whipped topping and lime zest if you like. Chill for 30 minutes before slicing.
