How to Make This Recipe
Step 1: Prep Your Pans
Preheat your oven to 350°F (175°C). Grease and flour three 8-inch cake pans, and don’t forget to line the bottoms with parchment paper. This is key to making sure your cake doesn’t do an “I’m stuck!” dance when you try to get it out.
Step 2: Mix the Dry Ingredients
In a large mixing bowl or the bowl of your stand mixer, combine the flour, sugar, baking powder, baking soda, and salt. Mix it up like you mean it!
Step 3: Incorporate the Butter
With your mixer on low, add the butter one tablespoon at a time. We’re looking to create a sandy, crumbly texture here. This step is essential for that fluffy cake we’re dreaming of.
Step 4: Add Oil and Zest
Now, toss in the oil and lime zest. Stir until it’s combined. Just the smell of limes will have you dreaming of beach vacations.
Step 5: Create the Milk Mixture
In a large measuring cup, pour the key lime juice and then fill it with milk until it hits the 1 ½ cup line. Whisk in your eggs and vanilla. It’s gonna get creamy and delicious!
Step 6: Combine Everything
Slowly add that milk mixture to your flour mixture while the mixer is on low. We want a silky-smooth batter here, so don’t be shy about scraping down the sides to ensure everything gets mixed in.
Step 7: Divide and Bake
Evenly divide the batter among the prepared pans (aim for about 460 grams in each pan if you’re measuring). Bake in your preheated oven for 26-28 minutes. Here’s the deal: when a toothpick comes out clean or with a few crumbs, you’re golden!
Step 8: Cool the Cakes
Let the cakes chill in their pans for 10-15 minutes. After that, run a knife around the edges and gently invert them onto a cooling rack to cool completely.
Step 9: Make the Key Lime Curd
In a small saucepan, whisk together the egg yolks, key lime juice, sugar, and salt. Add the butter and cook over medium-low heat, whisking constantly until thickened. This is where the magic happens!
Step 10: Create the Frosting
In a large mixing bowl, beat the softened butter and cream cheese until smooth. Gradually stir in powdered sugar until it’s fluffy and yum! Add the cooled curd one tablespoon at a time, mixing well after each.
Step 11: Layer and Frost
Once your cakes are cool, level the tops if they need it, and then frost each layer generously. Coat the outside and press those graham cracker crumbs around the base.
Step 12: Chill Out
If you’re using whipped cream frosting, pipe it on top and maybe add a bit more graham cracker or lime zest for flair. Let it chill in the fridge for at least 30 minutes—trust me, this helps everything set beautifully.
How to Store It
You can keep this Key Lime Cake covered in the fridge for up to five days, but honestly, it won’t last that long! For longer storage, you can freeze individual slices wrapped tightly. Just thaw them in the fridge when you’re ready to enjoy that tropical goodness again.
Expert Tips
- For the ultimate creaminess, try using room temperature ingredients. It really helps things blend beautifully.
- If your frosting feels too soft, just gradually add more powdered sugar until you get that spreadable texture.
- Love your cake a little more tart? Add an extra splash of lime juice to the frosting for a kick.
