Key Lime Pound Cake
When St. Patrick’s Day was approaching, I wanted to bake up a green-ish dessert. Since I adore Key Lime Pie, the bag of Key limes at the market brought my thoughts to a Key lime dessert, a Key lime pound cake to be precise.
With some lime zest in the cake batter, Key lime juice in the batter and icing, this tight crumbed, citrus laden cake was a heavenly, very pale green (if you use your imagination!) dessert.
Tips for Making a Perfect Pound Cake
The name itself, Pound Cake, gives the first clue this is no light and airy dessert. But the name itself goes back to the inception of this dessert, when a pound of butter, a pound of sugar, a pound of eggs and a pound of flour were the main ingredients in a pound cake.
- There are numerous variations on this basic formula. For example, in this Key lime pound cake, half the butter was swapped out for shortening, and lime zest and juice was added for flavor.
- PRO-Tip: If you want a picture perfect pound cake, you must prep your tube or Bundt cake properly. Grease with shortening, then dust with flour. Tap out any excess flour into the sink or garbage can.
- Read through the instructions before you start. Make sure you have all the ingredients on hand and get out the butter and eggs to allow them to come to room temperature.
- Use a stand mixer, if you have one, to beat the butter (and shortening in this recipe) until creamy. Be patient.
- Use brand name ingredients for the best results. Off-brand butters, for example, often have more water than name brands. And measure accurately.
- PRO-Tip: Add eggs one at a time, waiting until each egg is mixed in before adding the next. But be careful not to over beat. Once the last egg is incorporated, move onto the next step.
- Bake in the middle of the oven. Check to see if the cake is done by inserting a toothpick into the middle of the cake. If it comes out clean, your cake is done.
- Let the cake cool for 15 minutes on a rack, then carefully invert and remove from the baking pan. Allow to cool to room temperature on the rack before serving.
What is the Difference Between Standard Persian Limes and Key Limes?
The first difference is obvious, as Persian limes are much larger than Key limes. That’s why this recipe doesn’t call for the zest of Key limes, just the juice. Those suckers would be hard to zest!
Persian limes are tarter due to higher acidity, though they have fewer seeds. PRO-Tip: In a pinch, you could substitute Persian lime juice for Key lime juice, but avoid bottled lime juice. They cannot replace the taste of freshly squeezed lime juice.
