2) Easy Keto Apple Cinnamon Cake Recipe

This keto apple cinnamon cake recipe was born from pure dessert desperation. You know that late afternoon itch when you’re craving apple pie, but carbs? Yeah, not happening. So I stood in my kitchen, stared at some zucchini, and thought—what if? Turns out, you can fake apple texture like a pro.

That moment when someone takes a bite and says, “Wait, this is keto?” is priceless. It’s rich, subtly spiced, and goes down with a mug of tea better than you’d expect. I’ve made it for Sunday gatherings, late-night snacking, and it’s even been breakfast once or twice. No judgment here.

3) Ingredients for Keto Apple Cinnamon Cake

Butter: Softened just enough so you can cream it. Adds richness and structure to the cake.

Granular Erythritol: A keto-friendly sweetener that bakes like sugar without spiking your blood sugar.

Eggs: Two large ones hold everything together and help it rise in the oven.

Vanilla Extract: Rounds out the flavor and adds warmth.

Apple Extract: The real MVP here. Brings that apple flavor without the carbs.

Sour Cream: Moisture is key. Sour cream gives that nice tender crumb we love in cakes.

Almond Flour: The base flour that keeps this recipe gluten-free and keto-friendly.

Coconut Flour: Adds extra structure and soaks up moisture to balance the sour cream.

Baking Powder: Lifts the batter up without being too fluffy.

Cinnamon: A big warm hug for your taste buds.

Salt: Just enough to balance the sweetness and bring the flavors out.

Shredded Zucchini: Peeled and squeezed dry. This is your “apple” in disguise.

Butter (for sautéing): Adds flavor while softening the zucchini.

Cinnamon (for sautéing): Layers more spice right into the zucchini.

Apple Extract (for sautéing): Helps the zucchini taste like apple filling.

4) How to Make Keto Apple Cinnamon Cake

Step 1. Preheat your oven to 350°F and grease an 8×8-inch pan. No parchment? Grease it well and cross your fingers.

Step 2. Peel and shred the zucchini, then squeeze it with paper towels until it stops dripping. This part’s oddly satisfying.

Step 3. In a skillet over medium heat, melt butter and sauté the zucchini with cinnamon and apple extract for about 4 minutes. Let it cool slightly.

Step 4. In a large bowl, cream together the butter and erythritol until fluffy. This is your arm workout for the day.

Step 5. Mix in the eggs, vanilla, apple extract, and sour cream. Beat until it’s all smooth and luscious.

Step 6. In a separate bowl, whisk together almond flour, coconut flour, baking powder, cinnamon, and salt.

Step 7. Combine the wet and dry mixtures, then gently fold in the sautéed zucchini.

Step 8. Pour the batter into your pan and smooth the top with a spatula. No fancy swirls needed.

Step 9. Bake for 33 to 36 minutes. When the toothpick comes out clean, you’re golden.

Step 10. Let it cool fully. This is the hardest part. Then slice and serve.

5) Tips for Making Keto Apple Cinnamon Cake

Let’s be real—zucchini can be watery, so squeeze hard. You want that stuff dry before it hits the pan or your cake might turn soggy. We’re aiming for fluffy, not mushy.

Don’t skip the apple extract. It does the heavy lifting in the flavor department. If you try to sub it with real apples, you’re going to rack up carbs fast. This is one of those keto apple dessert recipes easy enough to make once and crave weekly.

Use room temperature ingredients if you can. Cold eggs and butter don’t mix well. Take ’em out while you’re shredding the zucchini and everything will blend smoother. Trust me, I learned this one the messy way.

6) Making Keto Apple Cinnamon Cake Ahead of Time

Want to get ahead of the dessert game? You can prep this cake the day before. Just store it in an airtight container once it cools. The flavors actually deepen overnight, which makes it even better on day two.

If you’re baking for a party, feel free to slice it in advance. Put wax paper between slices and store in a container. It keeps everything tidy and the cake stays moist.

Need to freeze it? No problem. Slice it first, wrap the pieces in plastic, then pop ’em in a freezer bag. They’ll hold up for a month. Just thaw and warm in the oven before serving.

7) Storing Leftover Keto Apple Cinnamon Cake

This cake stores like a champ. Wrap leftovers tightly or place them in an airtight container. They’ll keep in the fridge for up to five days.

<pIf you're looking for a quick snack, warm a slice in the microwave for about 15 seconds. The cinnamon flavor blooms and makes it feel fresh-baked again.

Don’t forget—you can freeze it too. This is a solid keto apple cake that comes back to life with just a little heat.
