This low carb red velvet cake is a new take on an old fashioned favorite. If you’re looking for a dessert that is as pretty as it is tasty, this might be the one.
This layer cake is completely refined sugar-free and void of gluten, but it has all the great tastes of a traditional red velvet cake.
Red Velvet – An old fashioned cake with simple flavors

Red velvet is made with cocoa powder, vinegar, and buttermilk. In our version, we skip the buttermilk (too many carbs!) and replace it with soured heavy cream.
The bright red colour comes from food dye. If you are not a fan of food dye, you can use beet root powder, but I will tell you that it is going to change the flavor of the cake. I love my veggies, but I cannot stand beets, so you’re on your own testing that one!
Food Coloring Tip
Americolor food gels are the best food dyes to use for a cake like this one. Since we need to add a significant amount of dye, you do not want to add anything with an off-putting taste.
Wilton has a no taste red dye that I have not personally tested, but I can tell you from experience to stay clear of their regular red & black food dyes; they taste terrible.
What sweeteners work best in this recipe?
I used allulose for the low carb red velvet cake layers, but you can use whatever granular sweetener you like the best.
Stick with granular sweeteners so the ratio of wet and dry ingredients is balanced.
I used powdered allulose for the cream cheese frosting because that’s the sweetener I like best lately. It doesn’t bother my stomach, doesn’t raise my blood sugar, and tastes great. So I reach for it most often.
But for the frosting, you can use any powdered sweetener you want. Use the one you like best.

Low Carb baking Tips for a Good Rise & Moist Crumb
We have an entire post dedicated to tips and tricks to make your low carb baking rise and turn out perfect every time.
For this recipe we need to make sure that we add in lots of air to help the leveners do their jobs.
- The cake batter for this recipe is going to feel thick. It won’t pour into your cake pans. You will need to spoon it in and level it all out.
- You will also want to prep your pans with parchment paper and grease very well.
- To prevent over-browning of the sides and bottom of your coconut cakes be sure to wrap your pans with tin foil. Coconut flour and some sweeteners tend to brown quickly. You can easily avoid this by using tin foil.
- Don’t skip the xanthan gum. Xanthan gum adds structure and holds the recipe together.
- Whip lots of air into your eggs before adding other ingredients. Whipping lightens the cake batter considerably.
- Don’t skip the vinegar. You can substitute lemon juice, but the extra acid is required to help those dense flours lift and rise in the oven.
- Be sure to sift all your dry ingredients. Sifting removes the irritating lumps from the flours and adds more air to the final batter.
- Ten minutes into baking cover the cakes with a piece of parchment paper or tin foil to prevent the tops from over-browning.
- Once the low carb red velvet cakes are out of the oven and cooled, level them off with a sharp serrated knife and save the bits you removed in a separate bowl. We need those bits for decoration.
Our New Favorite Brand of Sweeteners and Low Carb Flours
If you are looking for a great almond flour that doesn’t clump and tastes great, I highly recommend Besti.
I have tested all their products extensively in my baking, and I am over the moon with the quality of the ingredients. They also make the BEST coconut flour, and their sweeteners are consistent and lovely to bake with.
Tips to make low carb frosting
Here are some tips to make sure your whipped cream frosting comes out perfect every time.
- In a stand mixer, or with a hand mixer, whip cold cream cheese until it becomes spreadable.
- Scrape down the sides of the bowl to make sure all cream cheese bits are well blended.
- Add the heavy cream, flavoring, and sweetener to the bowl and mix on low until whip cream starts to blend with cream cheese. Add vanilla and emulsions and food coloring.
- Turn the mixer up and whip the mixture until soft and fluffy.
- If the icing begins to soften too much for spreading or piping, add it to the fridge for a few minutes to harden up a bit.
Decorating a cake doesn’t get any easier than this!
Take the bowl of cake bits that you removed from the low carb red velvet cake layers when leveling and grind them into a medium to a fine crumb. Place the crumbs on a parchment-lined cookie sheet and bake in the oven for 10 minutes at 300 F. This will help dry them out a bit.
If you find your cake bits are already dry enough you can skip the step above.
Frost the cakes, making sure to add a good layer of frosting between each cake. Smooth your frosting out, but no need to be fussy. The best part about this cake is it is old fashioned, so a bit of messy is excellent—no need to try to get perfection.
Once the cake is layered and coated with frosting use your cake crumbs and press them around the bottom of the cake into the frosting. Sprinkle the remaining bits on the top of the cake.
Storage & serving Suggestions
Keep the cake covered in the fridge for up to four days. After the fourth day, the cake starts to lose its freshness.
You can also prebake the cake layers and freeze them for up to a month. To defrost, remove them from the freezer the night before you need them and allow them to defrost in the fridge.
Pan Size Notes
For my recipe, I used three 6-inch Wilton cake pans. I like the presentation of a small 3 layer cake better than a large 2 layer cake.
But you can use 8 inch round pans (2) and bake for 35-40 minutes. Keep an eye out on the cakes around the 35-minute mark.
You can also make cupcakes. To make cupcakes use non-stick cupcake liners and fill them almost to the brim. Bake the cupcakes for 15-20 minutes.

Low Carb Red Velvet Cake With Cream Cheese Frosting
Ingredients
Cake Batter
- 1 1/2 cup allulose (powdered) * see sweetener section in post for replacements
- 3/4 cup butter
- 6 large eggs
- 1/3 cup full fat sour cream
- 3/4 cup heavy cream
- 1 Tbsp vinegar
- 3 cups almond flour
- 1/2 cup coconut flour
- 1 Tbsp baking powder
- 1/3 cup cocoa powder
- 1 tsp Xanthan gum powder
- 1 Tbsp vanilla
- 1/2 tsp salt
- 1 full tablespoon of red gel food dye
Frosting
- 1 Tbsp vanilla
- 1/2 cup whipping cream
- 1/2 cup allulose (powdered) * see sweetener section in post for replacements
- 1 cup (8 ounces) cream cheese
Instructions
- Preheat oven to 350 and prepare cake pans by greasing well.
- In a small bowl add the heavy whipping cream and add vinegar and stir. Set bowl aside.
- Add eggs to a mixing bowl and mix on high for 2 minutes.
- Melt the butter in the microwave, but do not overheat. We want the butter soft, but not too hot.
- Add 1 Tbsp vanilla, heavy cream, sour cream and vinegar, melted butter, and food dye to the egg mixture and blend until well incorporated.
- Sift almond flour, coconut flour, baking powder, xanthan gum, salt, and powdered allulose in a large bowl.
- Gently add the egg mixture to the dry ingredient mixture. Do not over mix.
- Divide batter between two 9 inch cake rounds (or three 6 inch cake rounds).
- Bake in a 350F oven for 30-35 minutes or until a toothpick inserted comes out clean.
- Cool on a cooling rack for about an hour.
- Once the cakes are cool, level the tops with a serrated knife and save the cake bits for decorating. See post for notes on cake decorating.
Whipped Cream Frosting
- Cube one cup of cold full fat cream cheese and add it to the bowl of a stand mixer and blend for 1 minute, until the cream cheese has no lumps. Scrape down the sides of the bowl if necessary.
- Add vanilla and powdered allulose.
- Add 1/2 cup of full-fat whipping cream to the bowl and mix on low for 30 seconds, until blended with cream cheese. Turn up to medium and then high until the whipped cream and cream cheese fluff up and resemble buttercream frosting.
- Do not overbeat. Over beating will cause the mixture to liquefy.

There are no instructions on when to add the sour cream….
Laura says
Hi Rhys, it needs to be added with the rest of the liquids to the eggs. I added the ingredient into that step. Sorry about that, we edit over and over and I don’t know how both of us missed that one. Thanks for asking the question! Cheers and Happy New Year.
Rhys says
Cheers to you as well and thanks for the quick response. HAPPY NEW YEAR!!! 🍾🍾🍾
Amanda says
is this recipe also gluten free?
Laura says
Hi Amanda, yes this recipe is gluten-free! You will need to check the ingredients on a few things to make sure that your brands are indeed gluten-free. Double-check the baking powder and your food color. I use AmeriColor gels that are 100% gluten-free. Most cocoa powders are gluten-free if you buy a good brand, but some of the cheaper versions can contain gluten ( I have had a few readers email me to let me know that). So as long as you verify those 3 ingredients you’re cake will be free from gluten. Cheers!
Joanne Natale says
I made this last night and it came out great! So moist. I modified the icing – doubled it to get the coverage I like and I added mascarpone to give it an Italian twist! One thing I learned from making the birthday cake was to sift all the dry ingredients first so that all the lovely air that I beat into the eggs didn’t deflate. I added the cocoa powder to the dry ingredients because it didn’t say in the recipe and I substituted yogurt for sour cream (very hard to find in Italy). This may not replace my other red velvet recipe, but it will definitely get a work out because of my diabetic friend who loves my baking. Thanks for doing so much work and sharing the fruits of your labour!
Laura says
Oh so glad you enjoyed it and thank you for pointing out the omission in the recipe, I will fix that immediately. Yogurt works great to replace the sour cream, I’ve made it with both and I can’t really tell the difference! I am very (very) jealous of your citrus trees!
Jas says
Hi there! Can I ask the specific type of vinegar that you use in the recipe?
Is it malt vinegar (brown), or is it a kind of white vinegar?
Thanks.
Laura says
I use apple cider vinegar usually, but white vinegar works as well – you can’t taste it at all in the recipe, it is only there to help the rising agents do their job. Cheers!
Wendi L says
Holey moley Laura! The texture of this cake is amazing; it’s as close to the real thing as I could have wished for! Everything else I’ve made with almond flour came out like hockey pucks, so I’m thrilled to be able to make a tasty, spongy diabetic friendly cake for my daughter’s birthday that everyone else will enjoy, too! I feel like I hit the jackpot finding in you! We have a bakery in our area that was featured on cupcake wars and they are Keto/vegan/gluten free only so I was planning on going there this weekend. They list ingredients for their cakes and your recipe is pretty spot on in comparison to their ingredient list (bonus; I already had everything needed in my pantry) AND is saving me at least $45 dollars!! THANK YOU THANK YOU THANK YOU!
Laura says
Hey Wendi, thank you so much for leaving such a great review, it made my day! I am thrilled you loved the cake texture because we worked on that forever. Cheers!
Cj says
With 1/3 cup cocoa powder, I’m sure this will be very good as a chocolate cake. Too much cocoa powder for a Red velvet cake. 😉
