This past week I filled an order for a lemon blueberry bundt cake from my home keto bakery. It’s not typically on my menu, but they loved my lemon blueberry muffins so much, they wanted the bundt cake as they were celebrating their baby’s one year birthday.
They did order a regular cake from a local bakery for baby and friends, but didn’t want to break their own keto diet. They were so thrilled with how the bundt cake turned out, they sent me pictures of their celebration, thanking me for the cake. This is the best way to convey to you that this recipe is truly tested.
I decided I had to share this bundt cake with you, which will be a wonderful addition to your Easter brunch or Mother’s Day brunch.
Lemon blueberry bundt cake is keto friendly, paleo friendly and gluten free. Sweetened with Swerve, powdered erythritol, and no spike in blood sugar, and safe for diabetics.

If you’re intimidated to make a bundt cake, because you’ve had problems in the past, I’m here to tell you that I have success every single time turning over my bundt cakes. I have to, as I have a bakery. I used to be fearful turning a bundt cake over, worrying about it sticking, until I developed a few tips.
I made this recipe into keto lemon blueberry muffins here.
Tips for Successful Bundt Cake
I am somewhat an expert on making keto bundt cakes as I’ve made hundreds of them for my keto bakery. I have great success in turning them over and making sure they are properly baked in the middle without over-browning.
- Heavily butter your bundt pan.
- Place bundt pan in freezer. This helps to prevent over-browning.
- Spray pan with a baking spray (I only use avocado oil or coconut oil spray).
- The cake is done at 210 F. but I take it out once it reaches 207.
- Set a timer for 15 minutes once you take your bundt cake out of oven.
- Use a silicone knife to gently go around the edges now and at the end of fifteen minutes.
- Using either a template (see this post) or a cake board, turn over.
- Cool completely before adding glaze.

Tips for Adding fruit to Bundt Cake
Remember that the bottom of your bundt cake pan is the top of your cake. Don’t put any fruit on top of batter (which will be your bottom). Before I add fruit, I will roll my blueberries in some swerve confectioner’s sugar to help them from easily sinking to the bottom.
Add in half of your batter to bundt pan before adding any fruit. Keep in mind that it’s natural for blueberries to sink a bit to the bottom. Notice that in this cake there is fruit at the top which adds to its prettiness.
How to add lemon flavor to a Keto Lemon Blueberry Bundt Cake
I do three things to add lemon flavor. Almond flour and coconut flour are the main ingredients and don’t absorb lemon flavor as easily as regular flour. This is why I add bottled lemon juice and extract to the fresh lemon juice and zest. You an use all fresh lemons.
- Fresh Lemon Juice and zest
- Bottled Lemon Juice (can use all fresh)
- Lemon Extract
Lemon Glaze for Keto Lemon Blueberry Bundt Cake
I have to share this Wilton Drizzle Spoon with you. It’s very inexpensive and so perfect for drizzling. I use this all day long in the bakery for all the glazes.
This drizzle is made with fresh lemon juice and Swerve confectioner’s sweetener. If you don’t have any confectioner’s, you can take the Swerve granulated and put it in your food processor until you get a powdery texture.
I avoid lemon extract for the glaze, as it’s not necessary, but if you could use it if you’re out of fresh lemon juice. Always taste first. You do want your glaze to be tart and lemony. You have to judge how thick your glaze is and make adjustments as needed. Use a spoon like this to drizzle glaze. Garnish with fresh berries.
I hope you enjoy this bundt cake as much as my customers do. Please let me know, and take a look around at all my keto bundt cakes.
