How to Make Key Lime Cake
Follow these simple steps to prepare this delicious dish:
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). Prepare two round baking pans by greasing them with coconut oil or lining them with parchment paper.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together all-purpose flour, baking powder, and casting sugar until well combined. Make sure there are no lumps—lumps are not invited to this party!
Step 3: Combine Wet Ingredients
In another bowl, mix melted coconut oil with fresh key lime juice and vanilla extract. Stir until combined—your kitchen should start smelling like tropical heaven right about now.
Step 4: Combine Mixtures
Gradually add your wet ingredients into the dry mixture. Stir gently until just combined; don’t overmix! We’re going for tender cake here—not rubbery shoe soles.
Step 5: Bake
Pour the batter evenly into your prepared pans and pop them into the oven. Bake for about 25-30 minutes or until a toothpick inserted into the center comes out clean. While waiting, feel free to practice your cake appreciation skills—you know, just in case someone asks you how much you love it later!
Step 6: Prepare Frosting
While cakes cool down, mix agar-agar powder with water according to package instructions and let it set slightly. Then whip together coconut cream (chilled!), remaining key lime juice, and some casting sugar until fluffy. Fold in your prepared agar-agar mixture gently.
Once cooled completely, frost one layer of cake generously with that dreamy frosting before stacking on the other layer. Top with more frosting and maybe even some lime zest if you’re feeling fancy!
Transfer slices onto plates and watch as people marvel at your baking prowess while they savor each tangy bite. Enjoy every moment as they ask who made this incredible creation—and don’t forget to point back at yourself proudly!
