Ingredients for the Best Castella Cake
Okay, let’s talk ingredients! You’ll want to grab these to make the magic happen. First, you’ll need 4 large eggs – aim for around 50-60g each. Next up is 120g of granulated sugar. Then, you’ll want 120g of cake flour, and don’t forget to sift it! It makes a difference, trust me! For liquid, grab 40ml of milk (whole milk is my go-to). And last but not least, 20ml of pure honey – the good stuff!
How to Make Castella Cake: Step-by-Step Instructions
Alright, let’s get baking! Don’t be scared; this is easier than it looks. Just follow these steps, and you’ll have a gorgeous Castella Cake in no time!
Preparing the Castella Cake Batter
First things first, grab a big bowl and whisk together those eggs and sugar. Whisk, whisk, whisk until it’s pale and thick – like, *really* thick. This takes a few minutes, so don’t give up! Then, gently fold in that sifted cake flour. Be careful not to overmix! You want to keep it light and airy. Finally, warm up the milk and honey together (just a little!), and gradually add it to the batter. Mix until just combined. That’s it! Batter done!

Baking Your Castella Cake to Perfection
Okay, crucial step: preheat your oven to 320°F (160°C). Don’t skip this! While that’s heating up, line a square cake pan with parchment paper. This is super important, or the cake will stick. Pour the batter into the prepared pan and pop it in the oven. Bake for 35-40 minutes, or until it’s a beautiful golden brown. To check if it’s done, stick a toothpick in the center. If it comes out clean (or with just a few moist crumbs), you’re good to go!
Cooling and Storing Your Homemade Castella Cake
Now, this is the hardest part: waiting! Let the cake cool *completely* in the pan before slicing. I know, it’s tempting, but trust me on this one. Once it’s cool, wrap it tightly in plastic wrap. This keeps all that lovely moisture in. You can store it at room temperature for a few days, or in the fridge for even longer. Enjoy!
Tips for the Perfect Castella Cake Every Time
Want to level up your Castella Cake game? Of course, you do! Here are a few tricks I’ve learned over the years to make sure yours comes out perfect every single time.
Choosing the Right Ingredients for Your Castella Cake
Seriously, ingredients matter! Go for high-quality eggs – the fresher, the better. Cake flour is a must for that delicate crumb, so don’t substitute it! And splurge on some good honey; it really makes a difference in the flavor. Trust me!
Achieving the Ideal Texture in Your Castella Cake
Okay, this is where the magic happens. Don’t skimp on the whisking! You want those eggs and sugar super thick and fluffy. When you’re folding in the flour, be gentle! And don’t overbake it! A slightly underbaked Castella Cake is way better than a dry one. You got this!
