What Is a Bundt Cake?

A Bundt cake is a type of cake that’s baked in a Bundt pan, which is round with a central tube and decorative, fluted sides. The unique shape of the pan not only gives the cake a beautiful, sculpted appearance but also helps it bake more evenly by allowing heat to reach the center of the cake.

Unlike other cakes that are defined by their ingredients or method, a Bundt cake is defined solely by its shape. You can make many different types of cakes in a Bundt pan—everything from lemon cakes and chocolate pound cakes to spiced holiday cakes or even keto-friendly versions.

Thanks to its elegant design and moist, dense texture, Bundt cake is often served at celebrations, brunches, or holiday gatherings. And because it holds glazes and drizzles beautifully, it’s perfect for topping with sugar-free glazes, fruit compotes, or even creamy frostings.

In short, Bundt cakes are a versatile, easy-to-make, and visually stunning dessert option for any occasion.

Is Bundt Cake Keto?

Traditional Bundt cakes are not keto-friendly because they’re typically made with wheat flour, sugar, and other high-carb ingredients. A single slice of regular Bundt cake can contain 30 grams of carbs or more, which doesn’t fit into a low-carb or ketogenic lifestyle.

However, the good news is that you can still enjoy a delicious Bundt cake on a keto diet by simply modifying the ingredients. In this keto version, we replace wheat flour with almond flour or coconut flour and use low-carb sweeteners like monk fruit, erythritol, or allulose instead of sugar.

The result is a cake that’s just as moist, fluffy, and flavorful as the traditional version—without the carbs. With only 4g net carbs per serving, this keto lemon Bundt cake proves you don’t have to sacrifice taste to stick to your health goals.

Ingredients Needed

You’ll be surprised how just a few simple, low-carb ingredients can create such a moist and flavorful keto lemon bundt cake. Here’s everything you need:

For the Bundt Cake

• Almond Flour – Use superfine blanched almond flour and sift it to remove clumps and achieve a light, smooth texture.
• Sweetener – I used erythritol, but you can also use monk fruit or allulose. Choose a granulated low-carb sweetenerthat suits your taste.
• Butter – Adds a rich, buttery flavor and keeps the cake tender.
• Eggs – Use large, room-temperature eggs to ensure the batter mixes evenly and the cake rises properly.
• Sour Cream – Adds moisture and a slightly tangy depth to the flavor.
• Lemon – You’ll need both fresh lemon zest and juice for that bright, zesty citrus flavor.
• Vanilla Extract – Use high-quality vanilla for a deeper, more balanced flavor.
• Baking Powder – Helps the cake rise and stay light and fluffy.
• Salt – Just a pinch to enhance all the flavors.

For The Lemon Glaze

• Powdered Sweetener – Use a finely ground sweetener for a smooth, lump-free glaze.
• Lemon Juice – Freshly squeezed lemon juice gives the glaze a vibrant, tangy kick.
• Cream Cheese – Makes the glaze ultra-creamy and adds a subtle richness.
• Vanilla Extract – Optional, but adds an extra layer of flavor.

How To Make This Keto Lemon Bundt Cake

This recipe may look too fancy, but you’ll be surprised to see how easy it is to make it in such a short time. Here is everything you have to do:

Preheat The Oven

Start by preheating the oven to 350 degrees F/ 177 degrees C and grease a bundt pan.

Preparing the Cake Batter

Add the softened butter and sweetener to a large bowl and mix until well combined.

Next, add the eggs, lemon juice, sour cream, and vanilla extract. Mix until frothy.

Mixing the Dry and Wet Ingredients

Add the almond flour, baking powder, salt, lemon zest over the egg mixture and mix until the cake batter is smooth.

Bake The Bundt Cake

Pour the batter into the greased pan and smooth the top.

Don’t overfill the bundt pan, as the cake may overflow during baking. Fill the pan about 2/3 full to allow room for the cake to rise.

Bake in the preheated oven for 50 minutes until golden brown or until an inserted toothpick comes out clean.

Remove the bundt cake from the oven and let it cool in the pan for at least 15 minutes, then turn it out onto a cooling rack and cool completely.

Make The Lemon Glaze

Mix the cream cheese, lemon juice, sweetener, and vanilla until well combined, then drizzle it over the cooled cake.

Tips For Making The Best Keto Lemon Bundt Cake

• Don’t overbake the cake – Start checking for doneness around the 40-minute mark. A toothpick should come out with a few moist crumbs — not wet batter. Overbaking can lead to a dry, crumbly texture.
• Avoid overmixing the batter – Mix just until the ingredients are combined. Overmixing can result in a dense and toughcake.
• Grease the bundt pan generously – Use butter or non-stick cooking spray to ensure your cake releases smoothly and keeps its beautiful shape.
• Use room temperature ingredients – Cold eggs or butter can cause the batter to curdle or mix unevenly. Let them sit out for 30 minutes beforehand for a smooth, lump-free batter.
• Let the cake cool completely – Allow it to cool in the pan for at least 15–20 minutes before inverting. This helps the cake firm up, release cleanly, and slice neatly.

Recipe Variations

Looking to give your keto lemon bundt cake a twist? Try one of these creative, flavor-packed variations:

• Add unsweetened dark chocolate chips to the batter for a rich, slightly bitter contrast to the lemon flavor.
• Mix in poppy seeds or fresh blueberries for a bright, fruity twist that adds both color and texture.
• For a decadent chocolate version, add 1 tbsp of cocoa powder to the batter and skip the lemon and poppy seeds – voilà, you have a keto chocolate pound cake.
• Create a cozy fall-inspired cake by adding pumpkin purée, cinnamon, nutmeg, and cloves to the batter, then top it with a smooth cream cheese glaze.
• Stir in shredded unsweetened coconut and top with a sugar-free coconut cream glaze for a tropical flavor profile.
• Add chopped nuts like almonds, pecans, or walnuts for a crunchy texture and a nutty, satisfying flavor.

Storing Ideas For Keto Lemon Bundt Cake

• Fridge – If there are any keto bundt cake leftovers, you can store them in an airtight container in the fridge for up to 5 days.
• Freezer – You can also freeze this sugar-free bundt cake. Wrap the cake in plastic wrap and freeze it for a few months until you want to eat it. To thaw the frozen pound cake, simply remove it from the freezer and let it sit at room temperature for a few hours until it is completely thawed.
