Ingredients Needed:

Keto Almond Milk Castella Cake Ingredients for pound cake, including flour, sugar, eggs, butter, and vanilla extract, arranged in a glass bowl on a white countertop in a well-lit kitchen.

You won’t need a chemistry degree to whip up this cake—just a few keto pantry staples. We’re talking :-

  • Eggs
  • Almond flour
  • Coconut flour
  • Avocado oil
  • Unsweetened almond milk
  • Erythritol (or another keto-friendly sweetener)
  • Vanilla extract (optional)
  • Cream of tartar

And just to make things fun, adding almond flour as your best friend in keto baking—it’s low-carb, gluten-free, and full of healthy fats that keep you satiated. Plus, almond flour gives this cake a subtle nutty flavor, which pairs beautifully with the vanilla and light sweetness of the erythritol. Coconut flour adds a little structure to balance out the fluffiness of the whipped egg whites. Boom! We’ve got ourselves a cake base that’s a win on all fronts.

How to Make Keto Almond Milk Castella Cake: Step-by-Step (But Easy-Peasy)


Let’s get this show on the road! Here’s a quick look at how you’ll transform a few humble ingredients into a keto masterpiece:

Prep and Separate: First things first—preheat that oven, line your pan with parchment paper, and separate your eggs like a pro. The key to the fluffiest Castella cake? That silky, whipped meringue. So, yes, we’re going to whisk those egg whites into soft peaks that look like they belong on a cloud.

Mix Your Batter: Now for the fun part! You’ll mix the hot oil into the almond flour and coconut flour, followed by the egg yolks and almond milk. This creates a smooth, velvety batter that’s just begging to be folded into meringue. Gently whisk in the egg whites, and voila! Your cake batter is complete.

Bake and Chill: Pour that beautiful batter into a lined baking pan, place it into a water bath (for that extra moisture), and pop it into the oven. After about 80 minutes, you’ll have a golden-brown, jiggly cake that’s ready to be devoured—though I suggest letting it cool for a bit to enjoy the full flavor and texture.

Storage and Serving Tips:

Storage Suggestions:

  1. Fridge :
    • Got leftovers? No problem! Let that cake cool completely, then tuck it into an airtight container like it’s checking into a 5-star fridge resort.
    • Your cake will chill (literally) for up to 5 days, and here’s a fun fact: it gets better with time, like aging cheese or that bottle of wine you’ve been saving. The flavors blend, and the texture stays soft and fluffy—yes, please!
    • Pro tip: Toss a little parchment paper on top before sealing the container. Why? To keep your cake as moist as a tropical island. Oh, and if you're feeling extra, wrap each slice in plastic wrap. Cake burritos for the win!
  2. Freezer :
    • Want to hoard that deliciousness? Slice the cake before freezing it! You can totally be that person who pulls a slice of keto heaven from the freezer like it’s no big deal.
    • Wrap each slice tightly in plastic wrap, like you’re swaddling a cake baby, then place them in a freezer bag or container. Your cake can chill out for up to 3 months in the deep freeze.
    • When you're ready to dig in, defrost the slices in the fridge overnight or let them hang out at room temperature for about an hour. No need to wait for dessert destiny!

Serving Suggestions:

  1. Room Temp Vibes:
    • Sure, you can dive into this cake straight from the fridge, but wait for it—let it sit at room temperature for about 20 minutes before serving. Why? Because the cake goes from "oh nice" to "HOLY FLUFFY CLOUD" when it warms up a bit. Trust me, your taste buds will thank you.
  2. Top It Like a Boss:
    • Keto Whipped Cream: Slap a dollop of keto whipped cream on there and watch your cake turn into a straight-up dessert party. Add a sprinkle of cinnamon or a dusting of cocoa powder for some extra oomph.
    • Fresh Berries: Strawberries, raspberries, or blueberries will make this cake sing. You get a little sweet, a little tart, and a whole lot of yum.
    • Keto Chocolate Ganache: Feeling fancy? Drizzle some keto chocolate ganache all over that cake like you’re a dessert Picasso. Chef’s kiss.
  3. Dessert Bar Magic:
    • Want to impress your keto squad? Set up a Castella Cake Dessert Bar! Think whipped cream, fresh berries, sugar-free syrups, and maybe some keto ice cream on the side. Let everyone go wild with their toppings—because we’re all about dessert customization, baby.
  4. Reheat It, Don’t Overheat It:
    • If you like your cake a little warm and cozy (same), pop a slice in the microwave for 10-15 seconds on low. This gives it a just-baked vibe, making it softer than a fluffy marshmallow but without the carbs. Seriously, try it—you won’t regret it.

There you have it! Whether you're keeping it chill in the fridge or serving it up in style, this Keto Almond Milk Castella Cake is about to be your new best friend in keto indulgence. Now go get your slice of cloud!

Frequently Asked Questions :

Q: Can I use regular flour instead of almond flour?
A: Nooo! Regular flour is loaded with carbs, which would completely defeat the purpose of a keto cake. Almond flour is low-carb, gluten-free, and adds a subtle nutty flavor that’s perfect for this recipe.

Q: Why is my Castella cake cracking?
A: Don’t stress! This usually happens if the meringue was whipped too stiff or if the oven temperature was a little too high. To prevent cracks, whisk the egg whites to soft peaks and bake the cake at a lower temperature.

Q: How long does this cake last?
A: You can keep this cake in the fridge for up to 5 days or freeze it for up to 3 months. Just thaw and enjoy—easy peasy!

Q: Can I make this cake dairy-free?
A: Absolutely! In fact, this recipe is already dairy-free, thanks to almond milk and avocado oil. But if you’re not dairy-free, feel free to swap in heavy cream for a richer flavor.

So, if you’re cutting down on milk or just looking for something a little lighter, almond milk is perfect. Plus, it’s usually fortified with vitamins D and E, so it’s like a mini health boost in every sip. And let’s be real, that nutty flavor?

Description

Enjoy this soft and fluffy Keto Almond Milk Castella Cake made with almond flour and almond milk. It’s low-carb, gluten-free, and dairy-free for guilt-free indulgence.

Ingredients
  • 8 large eggs (room temperature)
  • 3 oz 3.7 almond flour (for a smooth texture and nutty flavor)
  • 0 oz 0.53 coconut flour (helps with structure)
  • 3 oz 3.35 avocado oil (or coconut oil for a slightly tropical taste)
  • 3 oz 3.15 unsweetened almond milk (or coconut milk for a creamier texture)
  • 3 oz erythritol or monk fruit sweetener (granulated for sugar-free sweetness)
  • 1 tsp vanilla extract (optional for extra flavor)
  • 1/4 tsp cream of tartar (helps stabilize the meringue for the fluffy texture)
Instructions
    Step 1: Prep Your Oven and Pan
  1. Preheat your oven to 300°F (150°C). Line an 8-inch square baking pan with parchment paper, ensuring the paper extends a few inches over the top of the pan to support the rising cake.
  2. Step 2: Separate the Eggs
  3. Separate the egg yolks from the egg whites. Place the egg whites in a large mixing bowl and set them aside for later. Set the egg yolks in a smaller bowl.
  4. Step 3: Mix Dry Ingredients
  5. In a separate bowl, sift together the almond flour and coconut flour. Whisk until well combined.
  6. Step 4: Heat the Oil
  7. Heat the avocado (or coconut) oil until it reaches about 195°F (90°C) and pour it directly into the flour mixture. Stir well until combined.
  8. Step 5: Add the Almond Milk and Yolks
  9. Slowly mix in half the almond milk into the batter, then add the yolks and the remaining almond milk. Stir until you achieve a smooth, slightly runny batter.
  10. Step 6: Whisk the Meringue
  11. In your large mixing bowl, use an electric mixer to whisk the egg whites and cream of tartar. Gradually add the erythritol in three batches until the whites form soft peaks.
  12. Step 7: Fold the Meringue into the Batter
  13. Carefully fold a portion of the meringue into the almond batter to lighten it. Then, gently fold in the rest of the meringue, being careful not to overmix.
  14. Step 8: Bake in a Water Bath
  15. Pour the batter into the prepared baking pan and place it inside a larger pan filled with hot water (around 70°C). Bake for 80-85 minutes or until a toothpick comes out clean when inserted into the center.
  16. Step 9: Cool and Slice
  17. Once baked, remove the cake from the oven and peel away the parchment paper. Let it cool slightly before slicing into squares. Enjoy warm or cold!
