Keto Apple Spice Cake Recipe: A Cozy Treat You Can Actually Enjoy

Let’s be honest. If you’ve been living the keto life, desserts can feel like they belong on some distant memory shelf—sweet, warm, comforting smells teasing you from every bakery window. But hold up! I’m here to change that today. We’re making a Keto Apple Spice Cake that tastes so good, you won’t believe it’s low-carb. And yes, we’re doing it step by step, like we’re hanging out in your kitchen, aprons on, ready to bake together.

Grab a mug of coffee or tea, roll up your sleeves, and let’s get into it.

What Makes This Cake Special?

Here’s the thing: apples are kind of a no-go on keto. They’re naturally high in sugar. But we’re sneaky, and we’re going to cheat that warm apple flavor using something that’s keto-friendly: zucchini and apple extract. (Trust me, zucchini disappears in this cake, leaving you with all the cozy vibes of apples without the sugar crash.)

This cake is soft, full of cinnamon spice, and topped with a buttery frosting that feels like a warm hug. And yes, it’s totally keto.

Ingredients You’ll Need

I’m going to break this into sections so it’s easier to follow. Double-check your pantry!

For the Cake

  • 2 cups almond flour
  • 1/4 cup coconut flour
  • 1/3 cup granulated erythritol or your preferred keto sweetener
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1 1/2 tsp cinnamon
  • 1/4 tsp nutmeg
  • 1/4 tsp ground ginger
  • 1/4 cup unsweetened applesauce (optional, adds moisture and just a hint of apple flavor)
  • 1/4 cup melted butter or coconut oil
  • 3 large eggs, room temperature
  • 1 tsp apple extract
  • 1/2 cup grated zucchini (peeled)

For the Frosting

  • 1/4 cup unsalted butter, softened
  • 4 oz cream cheese, softened
  • 1/3 cup powdered erythritol
  • 1/2 tsp vanilla extract
  • 1/4 tsp cinnamon (optional but SO good)

Let’s Make It!

I’m going to keep this simple, so don’t worry if you’re not a seasoned baker. We’ll go slow, and I promise this cake is worth it.

Step 1: Prep Everything

Before we even touch the ingredients, preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan or line it with parchment paper so you don’t end up with a sticky mess.

Pro tip: Always let your eggs sit out for a bit so they’re not cold. Room-temperature eggs mix better with the other ingredients.

Step 2: Mix the Dry Ingredients

In a big bowl, stir together your almond flour, coconut flour, sweetener, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger. Use a whisk here to make sure there aren’t any lumps. Trust me, no one likes biting into a clump of flour.

Step 3: Handle the Wet Stuff

In another bowl, whisk your eggs until they’re nice and frothy. Add the melted butter (make sure it’s cooled a bit so you don’t scramble the eggs), apple extract, and applesauce if you’re using it. Mix until smooth.

Now, here’s the fun part: fold in the grated zucchini. I know it sounds weird, but this is our secret to a moist cake. You won’t taste it, and it won’t mess up the apple vibes we’re going for.

Step 4: Combine the Two

Slowly add the wet mixture to the dry ingredients. Stir gently—don’t overmix, or the cake might get dense. You’re looking for a batter that’s thick but smooth.

Baking Time

Pour the batter into your prepared pan and smooth out the top with a spatula. Bake it in the preheated oven for 30-35 minutes. You’ll know it’s done when the top is golden brown, and a toothpick poked into the center comes out clean.

Once it’s done, let it cool in the pan for about 10 minutes. Then transfer it to a wire rack to cool completely. (I know, the waiting is tough, but frosting a warm cake is a disaster waiting to happen.)

The Frosting

This is the part that takes the cake (pun intended). While your cake is cooling, let’s whip up a creamy, cinnamon-kissed frosting that’s so good, you might eat it with a spoon.

  • In a bowl, beat the softened butter and cream cheese together until it’s super smooth.
  • Add the powdered erythritol little by little, mixing as you go.
  • Stir in the vanilla extract and cinnamon.

That’s it. Simple, right? Pop the frosting into the fridge if your kitchen is warm, so it doesn’t get too soft while you wait for the cake to cool.

Assembling Your Masterpiece

Once the cake is cool, spread the frosting evenly across the top. You can get fancy and pipe it if you want, but I’m all about that rustic, homemade look.

For an extra sprinkle of magic, dust a little cinnamon on top or add some crushed pecans if you’re feeling fancy.

Why This Cake Works for Keto

Let’s talk carbs for a second.

  • The almond and coconut flours keep things low-carb without sacrificing flavor.
  • Erythritol gives it the sweetness without spiking your blood sugar.
  • Zucchini adds moisture (and secretly ups the veggie count for the day).

One slice comes out to about 4 net carbs, depending on your portion size. That means you can enjoy it without stressing over your macros.

Storage Tips

This cake is great fresh, but it gets even better the next day after the flavors settle. Here’s how to keep it tasty:

  • Fridge: Store it in an airtight container for up to 5 days.
  • Freezer: Slice it into portions, wrap each slice in plastic wrap, and freeze for up to 3 months. Just thaw in the fridge overnight before eating.

A Few Handy Tips

  • No apple extract? Try vanilla extract instead. It won’t have that apple twist, but it’ll still taste amazing.
  • Want more crunch? Toss some chopped nuts into the batter. Walnuts or pecans are a great choice.
  • Extra spice? Feel free to bump up the cinnamon or add a pinch of allspice.

Make It Yours

This cake is a blank canvas for all kinds of cozy vibes. Serve it warm with a dollop of whipped cream, or pair it with a cup of hot coffee on a rainy afternoon. Honestly, it’s the kind of dessert that feels like home—no matter where you are.

So, what are you waiting for? It’s time to get baking. Let your kitchen fill up with the smell of cinnamon and warm spices. If you try this recipe, let me know how it turns out! Whether you’re a keto pro or just dipping your toes into low-carb living, this cake is about to become a favorite.

Now, pass me a slice, would ya? 🍎
