Low Carb Lemon Ricotta Cake – Bright, Soft, and Naturally Sweet
This Low Carb Lemon Ricotta Cake is the kind of dessert that feels fancy but comes together with simple ingredients. It has a tender, moist crumb with a lovely citrus lift, and it’s not overly sweet. If you like cakes that taste clean and bright rather than heavy, this one hits the mark.
Ricotta keeps it soft for days, and almond flour adds a delicate, nutty flavor. It’s great for brunch, an afternoon coffee break, or a light dessert after dinner.
Ingredients
Method
- Prep the pan and oven. Heat the oven to 350°F (175°C). Grease a 9-inch springform pan and line the base with parchment for easy release.
- Mix the dry ingredients. In a bowl, whisk almond flour, coconut flour, baking powder, and salt until well combined. This helps prevent clumps and gives a consistent crumb.
- Cream butter and sweetener. In a large bowl, beat the softened butter with the granulated sweetener until light and fluffy, about 2–3 minutes. This adds air and improves texture.
- Add ricotta. Mix in the ricotta until smooth. Don’t worry if it looks slightly curdled—it will come together once you add the eggs.
- Add eggs and flavorings. Beat in the eggs one at a time, then add lemon zest, lemon juice, vanilla, and almond extract if using. The batter should be creamy and fragrant.
- Combine wet and dry. Gently fold the dry ingredients into the wet mixture until just combined. Avoid overmixing; a few tiny lumps are fine.
- Fill and smooth. Transfer the batter to the prepared pan and smooth the top with a spatula. The batter will be thick but spreadable.
- Bake. Bake for 35–45 minutes, or until the top is set and golden and a toothpick comes out with just a few moist crumbs. If the top browns too quickly, tent loosely with foil for the last 10 minutes.
- Cool completely. Let the cake cool in the pan for 15 minutes, then run a knife around the edges and release the springform. Cool fully on a rack before slicing. This helps the crumb set.
- Finish and serve. Dust with powdered low-carb sweetener if you like. Serve plain, with fresh berries, or a dollop of lightly sweetened whipped cream.
Why This Recipe Works
This cake leans on ricotta and almond flour for a soft, creamy texture that stays moist without extra sugar or starch. Lemon zest and juice bring fresh flavor without needing a glaze or heavy frosting.
Using a low-glycemic sweetener keeps carbs down while still delivering a cake that tastes like the “real” thing. A simple method—cream, fold, bake—means no tricky steps or special equipment. The result is a reliable, lovely cake you’ll want to bake again and again.

How to Make It
- Prep the pan and oven. Heat the oven to 350°F (175°C).
Grease a 9-inch springform pan and line the base with parchment for easy release.
- Mix the dry ingredients. In a bowl, whisk almond flour, coconut flour, baking powder, and salt until well combined. This helps prevent clumps and gives a consistent crumb.
- Cream butter and sweetener. In a large bowl, beat the softened butter with the granulated sweetener until light and fluffy, about 2–3 minutes. This adds air and improves texture.
- Add ricotta. Mix in the ricotta until smooth.
Don’t worry if it looks slightly curdled—it will come together once you add the eggs.
- Add eggs and flavorings. Beat in the eggs one at a time, then add lemon zest, lemon juice, vanilla, and almond extract if using. The batter should be creamy and fragrant.

How to Store
Refrigerate: Store covered in the fridge for up to 5 days. The flavor often improves by day two as the lemon settles in.
Freeze: Wrap individual slices tightly and freeze for up to 2 months.
Thaw overnight in the fridge or at room temperature for 30–45 minutes.
Room temp: Because of the ricotta, keep it at room temperature for no more than a day. After that, refrigerate.
Health Benefits
- Lower in carbs: Almond and coconut flours keep net carbs down compared to wheat flour.
- Better blood sugar control: Using low-glycemic sweeteners helps reduce blood sugar spikes.
- Protein and fats: Ricotta and almond flour add protein and healthy fats, making the cake more satisfying.
- Nutrients from almonds: Almond flour provides vitamin E, magnesium, and fiber.
- Real citrus: Fresh lemon adds vitamin C and bright flavor without extra sugar.
What Not to Do
- Don’t skip the parchment. This cake is tender; parchment ensures a clean release.
- Don’t overmix the batter. Overmixing can make the crumb dense. Fold gently until just combined.
- Don’t underbake. A wet center won’t set properly.
Look for a lightly golden top and a toothpick with moist crumbs, not batter.
- Don’t use almond meal. Coarse almond meal makes the cake gritty. Choose fine, blanched almond flour.
- Don’t use cold ingredients. Room-temperature eggs and softened butter help the batter emulsify for a smoother texture.
- Don’t drown it in lemon juice. Too much liquid can make the cake collapse. Stick to zest plus a measured amount of juice.
Recipe Variations
- Poppy seed twist: Add 1 tablespoon poppy seeds for a subtle crunch and bakery-style vibe.
- Blueberry lemon: Fold in 3/4 cup fresh blueberries tossed with a teaspoon of almond flour.
Bake a few minutes longer if needed.
- Lemon glaze: Whisk powdered low-carb sweetener with a little lemon juice and drizzle over the cooled cake. It adds shine and extra tang.
- Olive oil swap: Replace half the butter with extra-virgin olive oil for a Mediterranean note and super-moist crumb.
- Orange ricotta cake: Use orange zest and juice instead of lemon for a warmer, sweeter citrus profile.
- Almond topping: Scatter sliced almonds on top before baking for a toasty crunch.
FAQ
Can I make this cake dairy-free?
You can try a thick dairy-free ricotta alternative and use a neutral oil instead of butter. Texture may be slightly different, but the cake should still be tender.
Choose a plant-based ricotta that isn’t too watery.
Which sweetener works best?
Erythritol or an erythritol/monk fruit blend holds structure and gives a clean taste. Allulose is great too but can brown faster and make the crumb a bit softer. Adjust baking time and tent with foil if browning quickly.
Can I use only almond flour?
Yes.
The small amount of coconut flour helps with structure, but you can omit it and add 2 extra tablespoons of almond flour. The cake may be a touch more delicate.
Why did my cake sink in the middle?
Common causes are too much liquid, underbaking, or opening the oven door too early. Measure lemon juice carefully, bake until fully set, and avoid peeking for the first 25 minutes.
Let it cool in the pan to stabilize.
Do I need a springform pan?
It’s helpful for easy release, but a well-greased and parchment-lined 9-inch round cake pan works. Let it cool longer before turning out to avoid breaking the cake.
Can I reduce the sweetener?
Yes, but keep at least 1/2 cup for balance and proper texture. Less sweetener may make the crumb slightly drier, so consider adding 1 extra tablespoon of butter or a splash of cream.
How do I know when it’s done?
Look for a golden top, edges pulling slightly from the pan, and a toothpick with moist crumbs.
If the center still looks glossy or jiggles, give it more time.
Is this keto-friendly?
Yes, when made with low-carb sweetener and almond/coconut flours, it fits most keto plans. Keep portions reasonable and check your specific macros.
In Conclusion
This Low Carb Lemon Ricotta Cake is bright, soft, and simple enough for any day of the week. With clean flavors and a moist, tender crumb, it satisfies a dessert craving without a sugar crash.
Keep it classic, or try one of the easy variations to make it your own. Serve it with berries, coffee, or tea, and enjoy a slice that tastes like sunshine.
