Keto Lemon Pound Cake Recipe (Gluten-Free, Sugar-Free)

This keto lemon pound cake recipe creates a sweet treat with a tart lemon flavor and an optional sour cream glaze. It is a lemon loaf to love. And it will disappear quickly, too, since a slice of keto lemon pound cake is appropriate at just about any time of day.

A few simple ingredients and just minutes of prep time come together to create a marvelous treat that’s sure to become one of those easy keto recipes you’ll revisit time and time again.

This keto lemon pound cake recipe makes a sweet, tart and tender lemon loaf that’s also gluten-free, grain-free, dairy optional and packed with intense lemon flavor (all from real lemons, no lemon extract!).

I am a sucker for any kind of lemon-y dessert and I LOVE this lemon pound cake recipe.

Since I first posted it a couple of years ago, I’ve adapted it a bit to create a slightly larger loaf (more servings!) as well as a sweet lemon glaze to go on top.

Think of it as the low-carb version of a Starbucks lemon loaf– that’s the inspiration.

With each keto lemon pound cake I bake, I find even more versatility in how to enjoy it. A few options for you:

• dress up a piece with lemon curd (or may I suggest lime curd for an extra tart treat), coconut whipped cream and fresh berries because layers always bring a good dessert to the next level
• top it with strawberries and whipped cream for an easy, lemon version of keto strawberry shortcake
• serve up a slice for breakfast (my kids are all about this one, and can you really beat breakfast cake?!)

This keto lemon pound cake is so tasty and tender, and it’s a lemon pound cake recipe you’ll make over and over again.

I use a combination of almond flour and coconut flour which results in the perfect texture: moist but not too crumbly, dense and flavorful as any good pound cake should be.

As for the fat content, I’ve found that I like it best with grass-fed butter or extra virgin olive oil (opt for that if you’re dairy-free).

Olive oil cakes are delightful, and the flavor of extra virgin olive oil is extra nice with lemon. I especially love Olio Piro extra virgin olive oil, an award-winning olive oil with high antioxidants that is made in Italy (affiliate).

Overall, oil will make the cake a bit less dense compared to butter, but the differences are pretty subtle. I haven’t tried it with avocado oil but I’m sure it will also work out just fine.

This keto lemon pound cake is:

• easy to make
• low-carb with only 3 net carbs per serving
• gluten-free, sugar-free and dairy optional
• super versatile

Lemon is a wonderful flavor to incorporate into keto baking as it adds a delicious tartness without the carbs.

I have always loved lemon-y treats and this keto lemon loaf strikes the perfect balance between dessert and snack, without any guilt. 😉

To make it, you will need:

• extra virgin olive oil or grass-fed butter
• granulated monk fruit sweetener (I use Lakanto which is my favorite keto sweetener for baking)
• vanilla extract
• large eggs
• sour cream (or unsweetened coconut cream if dairy-free)
• fresh lemon juice and lemon zest
• almond flour
• coconut flour
• baking powder
• salt
• xanthan gum (optional)

keto lemon pound cake recipe

This lemon cake recipe is so simple, you can easily whip one up in no time! Take a look at the process (for all the details, check out the recipe card at the bottom of the page):

1. Mix the oil/butter and sweetener: Cream together the melted butter or oil and the sweetener in a large mixing bowl with a hand mixer (or using an standup mixer). Add in the rest of the wet ingredients: fresh lemon juice, lemon zest, vanilla extract, eggs and sour cream. Scrape down the sides of the bowl with a rubber spatula as needed and mix until well combined.
2. Mix the dry ingredients: In a separate bowl, whisk together the dry ingredients. This helps break up the almond flour to prevent any lumps.
3. Stir the batter: Pour the egg mixture into the almond flour mixture and mix until it is incorporated and there are no streaks of flour.
4. Bake the keto lemon pound cake: Line a 9 x 5-inch loaf pan with parchment paper. Pour the batter into the prepared loaf pan and transfer it to the oven. Bake at 350°F for 45-50 minutes, or until done. If the top of the pound cake begins to brown around 30-45 minutes into the baking time and the center isn’t done yet, place a sheet of parchment paper over the loaf to protect the top from getting too dark.
5. Cool and serve: Allow the low carb lemon cake to cool in the pan for at least 30 minutes before transferring it to a cooling rack. Let it cool completely. If desired, make a glaze and pour it on top of the cake. Place it in the freezer for 10 minutes to set the glaze.

tips for the best keto lemon pound cake

• Please, please, PLEASE do not substitute the flours. The almond flour and coconut flour combine well to create a specific texture, and they cannot be substituted 1:1 for each other.
• Almond meal cannot be substituted for almond flour. Almond meal is ground, whole almonds while blanched almond flour has the skins removed and is ground super fine.
• Granulated monk fruit is often found as a blend of monk fruit and erythritol. If you don’t have granulated monk fruit, you can substitute plain erythritol (like Swerve), but you might find it has more of a cooling aftertaste.
• Parchment paper is your friend! Line baking dishes with parchment paper to easily remove the bread after baking. For this keto pound cake recipe, I leave paper hanging over the sides of the pan which I then use to lift the loaf out after it has cooled.
• Using butter will create an extra dense texture in this lemon pound cake, a bit more true to a traditional pound cake. A few different oil varieties that will work include olive oil, coconut oil and avocado oil.
• If you’re using coconut oil, be sure to let the eggs and sour cream come to room temperature. Cold eggs and cold sour cream will harden the melted coconut oil and make the cake batter lumpy.
