Simple How-To Steps
- Ready the Glaze:
- In a bowl, stir together the powdered sugar, splash of Key lime juice, and a bit of vanilla until smooth Set aside for later—you’ll want it pourable
- Give the Cake Time to Cool:
- Once it’s baked, let it sit in the pan about ten minutes Flip it out onto a rack and let cool all the way so it holds together well
- Get Your Pan Prepped:
- First, turn on your oven to the right setting Grease and flour a bundt or loaf pan well so nothing sticks
- Time for Batter:
- Spoon all the finished batter into your pan Smooth the top, then place on the center oven rack Bake til the top is gold and a toothpick comes out clean This usually takes around an hour
- Mix Flour and Leaveners:
- Whisk cake flour, baking powder, and salt in a separate bowl That way it all gets mixed in even
- Beat in the Eggs:
- Crack your eggs into a little bowl Add one by one to the mixer, blending each time so it’s all blended and smooth This is what keeps your cake stable
- Cream Butter, Shortening & Sugar:
- Beat soft butter, shortening, and sugar together on medium until it goes fluffy and light Give it about 3 to 5 minutes This helps air get trapped so your cake rises well
- Combine Wet Bits:
- Stir in heavy cream, Key lime juice, lime zest, and a splash of vanilla Go gently, just mixing until it’s all together
- Join Wet & Dry:
- Add the dry mix into the wet a bit at a time Stir just until you see no flour streaks Stop when it looks even—overmixing messes up the crumb
- Icy Finish:
- Drizzle your glaze over the cold cake Let it sit for ten minutes to set—it cuts clean and looks great
- Dishing Up:
- When the glaze is set, slice and serve The sweet tart coating makes each piece sing

I love how the scent of lime zest fills my house when I bake It always throws me back to sun-drenched days in Florida as a kid—citrus desserts there were always exciting and full of zing
Fresh Storage Ideas
To keep it soft, just pop the cake in a sealed container on your countertop—it’ll taste great for days For saving leftovers longer, wrap each slice and stash them in the freezer The glaze holds tight so you can carry slices for parties or hand out as sweet gifts
Swaps that Work
No Key limes? Regular limes are close enough—just a bit softer on flavor Always squeeze your own juice for that punch! If you’re out of cake flour, use all purpose but take out two tablespoons per cup and put cornstarch in instead—turns out just as tender
How to Serve
This cake really shines on its own but is also awesome with a spoonful of softly whipped cream For something tropical, try coconut cream or sprinkle with toasted coconut I love it with a glass of iced tea or strong coffee for laid-back hangouts

Frequently Asked Questions
- → How can I keep this cake soft and moist?
Let your butter soften up before beating it with sugar and shortening. When you add the dry stuff, just mix it in gently. That stops the cake from getting tough.
- → Is it OK to use regular limes instead?
Totally! Regular limes work, though the cake will be a little less tart. Still tasty.
- → What’s sifting the flour do?
Sifting gets rid of lumps and puffs up the flour, which makes the cake lighter once it’s baked.
- → What’s the best way to store extra cake?
Wrap it up tight. Leave on the counter for 3 days, or throw it in the fridge if you want it to last longer.
- → When should the glaze go on?
Wait for the cake to cool off all the way, then drizzle over the glaze. Give it at least 10 minutes to set before you cut it up.
