This keto lemon poppy seed cake has been adapted from my lemon coconut cake with cream cheese icing, which has been a huge hit amongst my readers. It’s nut-free, as coconut is technically a drupe, however, you could use sesame seed flour as a nut-free alternative as well.
What is Nuvia Baking?
Nuvia Baking is a blend of erythritol, soy protein isolate, chicory root extract and stevia extract. It is designed to be a one-for-one sugar replacement in baked goods, specifically home baking.
Nuvia tastes and browns, and gives rise to baked goods just like regular granulated sugar. It can act as a direct replacement for sugar whenever you are searching for a sweet alternative you can feel good about.
The coolness of the erythritol is balanced out by the sweetness of stevia, giving this blend a very similar taste to sugar.
Generally, I use erythritol mixed with monk fruit in most of my baking, but in this lemon poppy seed cake, I believe Nuvia actually works really well.
This sweetener does contain soy protein isolate, which is derived from a legume. However, this is not going to impact your blood sugar levels in any way since erythritol, stevia and monk fruit are pretty much the only sweeteners that won’t.
Looking for a Keto Lemon Pound Cake Recipe?
Sure, you could make this into a regular pound cake by leaving out the blueberries and poppy seeds, but seriously, who doesn’t love lemon and poppy seeds? I used gelatin in this recipe as it always gives low carb baked goods more of a cake type consistency.
Gelatin is also useful in chocolate chip cookies to make them chewy as they cool.

- 1/3 cup lemon juice about 1 large lemon
- 1/3 cup Nuvia Sweetener
- 2 Tbsp poppy seeds
- 2 tsp gelatin powder
- 1/4 tsp salt
- 1 cup blueberries frozen is fine
Icing
- 1 cup Nuvia Sweetener
- 1 Tbsp salted butter room temp
- 2 Tbsp lemon juice use enough to turn the mixture to a fluid glaze
Instructions
Cake
- Preheat the oven to 180 C (350 F).

- Fold the blueberries into the mixture using a spatula.

Icing
- Using a food processor, blend the Nuvia sweetener until it resembles confectioners sugar (icing sugar).
- Pour this mixture into a bowl along with the butter and a small amount of lemon juice. Mix together with a hand mixer until smooth; keep adding lemon juice until it turns into a glaze, thick enough to coat the back of a spoon.
- Place this in the fridge until your cake is ready to go.
Once Cake Is Cooked
- Remove from the oven, and let it completely cool before icing.

Hi,
Can I use Stevia instead of Nuvia Sweetener??
Hi Aaron, Thank you for an amazing recipe. I made it last week but replaced poppy seeds with Chia seeds; for the reason I had so much of them in my pantry. I am soon to make my second attempt of it this weekend, with poppy seeds.
I’m intrigued! I’m allergic to soy so using the Nuvia as listed isn’t an option for me. Will an erythritol/stevia replacement work? I’d like to use a small sized bundt pan instead of a loaf pan. Can you think of any concerns to be aware of? My plan is to omit the blueberries (this time) and pipe lengths of your Lemon Curd down the sides of the bundt shaped cake from the top, for a special occasion. I may also add a few edible flowers for decoration, too. I’d love your feedback.
Hi Jacki,
Yes, a stevia / erythritol based sweetener will definitely work as well. Thanks for asking!
