Key Lime Cake
Jun 15, 2024 02:44 AM
Built on all the classic, favorite flavors of key lime pie, this key lime cake is fun, refreshing, and brilliantly flavored! It’s made with three moist, sweet vanilla cake layers, a tart key lime frosting, and (optional, but recommended) sky-high dollops of whipped cream.
Why You’ll Love This Key Lime Cake
Cake layers: the cake layers are subtly infused with key lime flavor, but they still have a sweet vanilla cake taste, so the cake isn’t overpowered by tartness.
Frosting: to achieve the most key lime flavor in the frosting, we’ll stir in a homemade lime curd. I first used this technique in my lemon frosting (this is a game changer for infusing flavor into frostings!).
Decoration: a crown of stabilized whipped cream and miniskirt of graham cracker crumbs puts things over the top and gives everything an authentic key lime pie taste and feel.
Technique: from the reverse creaming method used to make the tender cake layers to the curd-infused frosting, every bit of work you put into this cake will be well worth the reward.
