🧁 Step-by-Step: How to Make Low-Carb Cake in a Jar
Follow these easy steps to create the most decadent, melt-in-your-mouth low-carb dessert you’ll ever taste.
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C).
Grease four small glass jars (or ramekins) with cooking spray or a touch of butter. Make sure the jars are oven-safe.
Step 2: Combine the Dry Ingredients
In a medium-sized bowl, whisk together:
- Almond flour
- Erythritol
- Cocoa powder
- Baking powder
- A pinch of salt
Mix well to eliminate clumps and distribute the cocoa evenly.
Step 3: Mix the Wet Ingredients
In another bowl, beat the eggs until slightly frothy. Add almond milk and vanilla extract. Whisk until smooth and consistent.
Step 4: Blend Wet and Dry Ingredients
Gradually pour the dry mixture into the wet mixture while stirring gently. Don’t overmix — this ensures your cake stays soft and tender.
Step 5: Fill the Jars
Divide the batter evenly among the jars, filling each about halfway.
Leave space for the cake to rise while baking.
Step 6: Bake in a Water Bath
Place the jars in a baking dish filled with about one inch of hot water. This water bath creates gentle steam, ensuring a moist and fluffy cake texture.
Bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean.
Step 7: Cool and Serve
Carefully remove the jars from the oven and let them cool for 10 minutes.
Top with sugar-free whipped cream or fresh berries before serving.
🍓 Pro Tips for the Perfect Low-Carb Cake
Want bakery-quality results every time? Here are expert-level tips to elevate your dessert game.
1. Don’t Overmix
Overmixing makes almond flour dense and heavy. Stir just until the ingredients are combined.
2. Use Room-Temperature Ingredients
Cold eggs or milk can cause uneven baking. Let them rest at room temperature before starting.
3. Try Microwave Baking for Speed
If you’re short on time, this recipe also works in the microwave! Cook one jar for 60–90 seconds on high power. The texture will be slightly softer but equally delicious.
4. Add a Flavor Twist
- Stir in sugar-free chocolate chips for extra richness.
- Add a spoonful of unsweetened peanut butter to the batter for a nutty surprise.
- Sprinkle cinnamon or instant espresso powder for depth and aroma.
5. Create a Layered Dessert
Once baked, cut the cake in half, add a layer of whipped cream or sugar-free chocolate ganache, and assemble it back in the jar for a layered “mini trifle” effect.

💬 Frequently Asked Questions (FAQs)
1. Can I make this cake ahead of time?
Absolutely! You can bake the jars, cool them, and refrigerate them for up to 3 days. Just warm slightly before serving.
2. Can I make this dairy-free?
Yes! Replace almond milk with coconut milk and butter (if used) with coconut oil.
3. What can I use instead of almond flour?
You can use sunflower seed flour in equal amounts — it’s nut-free and still low in carbs.
4. Can I use stevia instead of erythritol?
Yes, but stevia is much sweeter. Use a small amount (check your brand’s conversion chart).
5. Can I bake without the water bath?
You can, but the cake might dry out slightly. The steam ensures a soft and fluffy texture.

🧑🍳 Chef’s Notes & Pro Insights
Creating a low-carb cake that’s moist, soft, and rich can be tricky — but the secret lies in ingredient balance and baking technique.
- Almond flour doesn’t absorb liquid like wheat flour, so always use exact measurements.
- Erythritol doesn’t caramelize like sugar, so expect a lighter color.
- Never skip the water bath; it mimics professional steam baking.
When done right, your cake will have a tender crumb and a slightly crisp top — the perfect contrast of textures.
