Key Lime Bundt Cake with Margarita Frosting

I’m always mentioning my CSA, but what I currently receive isn’t a share from a single farm. I’ve been receiving a box every other week from Farmhouse Delivery, and they combine produce, meat, dairy, eggs, and local artisanal products in a flexible plan. The boxes are delivered to your door, and you can choose to receive one every week rather than every other, but that would be a little too much for a two-person household. Because the items are gathered from a few different local farms, each box is filled with varied and interesting things. There's always something exciting and unexpected. A couple of weeks ago, our delivery included some key limes, and a few ideas came to mind immediately. I knew I’d seen a key lime cake I really wanted to try. After a little searching, I found it again on Cookie Madness. This is a great summer cake. It’s a sturdy but tender bundt with lots of flavor from the key lime juice and zest in the batter, and the frosting has all the basic ingredients of a good margarita.

The cake is made with cake flour which gives it a velvety texture. The dry ingredients were sifted together, and then eggs were separated. The egg whites were beaten to soft peaks in a separate bowl and set aside. The yolks were combined with softened butter, sugar, and lime zest. As usual, I used all butter here rather than a mix of butter and shortening. The dry ingredients were added to the butter mixture alternately with lime juice and sour cream. You know a cake is going to be good when sour cream’s involved. Last, the egg whites were folded into the batter, and it was poured into a prepared bundt pan. For the frosting, softened cream cheese, butter, and confectioner’s sugar were mixed, and tequila, Grand Marnier, and lime juice were added. The frosting should be thin enough to run down the sides of the cake but thick enough to hold some shape. Tasting and testing the frosting is a fun process as you can add additional lime juice, tequila, or confectioner’s sugar to achieve the margarita taste you want and the thickness that seems right.

Bundt cakes are so low-maintenance with their built-in good looks from the pan in which they’re baked and their need for just a simple drizzly frosting at the most. Add to that great flavor like key lime, and you’ve got a fantastic dessert. Getting to use some locally grown citrus in this delicious cake was a bonus for me, and well, the familiar flavor of a margarita was, you know, icing on the cake.
