This easy Keto Lemon Cake with Poppy Seeds is heavenly, topped with a sugarfree lemon glaze and raspberries.
This is the ultimate healthy lemon poppy seed bundt cake but if you like citrus desserts, you might also like my Keto Orange Angel Food Cake and if you love bundt cakes, check out my Keto Chocolate Bundt Cake.

I love baking bundt cakes especially in beautiful pans which make decorating a lot easier. You can, for example, simply sprinkle powdered sweetener on a bundt cake, but I can rarely stop at that.
Pro tips for a perfect bundt cake
- Use a quality nonstick bundt pan: I recommend Nordic Ware’s premium nonstick bundt pans for a number of reasons. Firstly, they are made of cast aluminum which heats evenly for perfect cake texture and color. Secondly, they come in a number of stunning designs such as the model I used for my cake: the Nordic Ware Heritage Bundt Pan.
- Prep the pan: For glutenfree baking with almond flour, I recommend brushing your nonstick pan with butter or grease.
- Don’t overbake your keto lemon cake: Overbaking leads to drying. Make sure you remove your cake from the oven when a knife or skewer comes out clean. If you bake a lot of bundts, you might want to pick up Nordic Ware’s Bundt Cake Thermometer, since the tip turns red when the cake is done.
- Cooling is also important: Cool in pan for 10 minutes only. Any longer than 10 minutes and the sugars start to cool and can start to stick to the pan.
- Clean your bundt pan properly: Baking sprays can leave a residue that builds up and turns into a sticky cake glue that, in fact, refuses to let go of your cake sponge. So, it is important to always clean your bundt pan properly. Regardless of whether I use butter or baking spray, I wash my Nordic Ware bundt pans with Dawn Powerwash Spray after every bake. Specifically, I apply the Powerwash Spray directly to pan, no water, and let it stand 10 minutes. Then I wipe it off or, if necessary, scrub the pan well with a plastic or nylon bristled brush, and finally rinse with hot water.
The ingredients for keto lemon poppy seed bundt cake
- Almond flour – fine, blanched
- Granulated sweetener – I use natural, zero-calorie sugar replacements such as monk fruit.
- Baking powder
- Poppy seeds
- Salt
- Avocado oil or puréed avocado – If you use puréed avocado, the batter will turn green but this will fade during baking and give the cake a dark yellow or golden yellow tone.
- Eggs
- Yogurt – I use non-fat Greek yogurt or sour cream.
- Vanilla extract
- Lemon juice – fresh squeezed
- Lemon extract – enhances the flavor
- Powdered sweetener – To make the lemon glaze, I use powdered monk fruit which has 0 calories, 0 carbs, and a glycemic index of 0. If you don’t have powdered sweetener, it’s easy to make some: Just pulverize granulated sweetener in the food processor for a few seconds and you’ll have powdered sweetener.

It doesn’t get easier than this lemon glaze. Simply mix lemon juice into powdered sugar until desired sweetness and consistency is attained. Then drizzle glaze onto keto lemon cake.
