Keto Kentucky Butter Cake

by hungryelephant

A southeastern American treat – made KETO. This delicious butter cake is a staple in some U.S. households and anything with butter – you bet I HAD to make it.

So original butter cake is made with buttermilk.. since we can’t use that on keto, I replaced that with sour cream so it will be nice and MOIST. It worked perfectly!

One problem that I had was that there was TOO much syrup – so I altered the recipe to be JUST right. A great thing about this cake is that if you don’t want to use the syrup, it will still taste delicious and moist!

 

 

We’ve gotten so many great reviews, here’s just a sample: 

Keri on Facebook says: 

I make this all the time. I add a chocolate ganache on top for birthday cakes. It’s our favorite cake. Ah-may-zing!!!

Sheryl on Instagram wrote: 

One of the best cakes I have ever made!

Avelino on Instagram praised: 

This is for real the best Keto breath ever! I am obsessed with it! I have made tons of desserts since I stated Keto and nothing compres to this! Yes it is a dream come true!

Hope you enjoy!

Keto Kentucky Butter Cake

Prep Time: 15 minutes
Cook Time: 30 minutes
Total Time: 45 minutes

A southern American treat made keto!

Ingredients

Cake

Syrup

  • 1/4 cup (50g) butter
  • 1/3 cup (60g) sugar substitute (I used erythritol)
  • 1 tbsp vanilla
  • 2 tbsp water

Instructions

  1. In a mixing bowl, whisk together the cake ingredients.
  2. Pour into a greased or floured bundt cake pan.
  3. Bake at 350°F / 175°C for 35 minutes.
  4. While the cake bakes, melt the butter in a pot over medium heat.
  5. Whisk in your sugar substitute, vanilla and water. Heat and stir until the sugar substitute has dissolved
  6. Once the cake is done, use a skewer or end of a utensil to poke several small holes into the top (technically the bottom) of the bundt cake. 
  7. Pour the butter mixture around the cake, making sure the holes are filled with the butter. Keep swirling the pan around until your mixture has dissolved into the cake.
  8. Set aside and let it cool for 1 hour.
  9. When you’re ready to serve, place a plate on top of the bundt pan and flip it around so the cake pops right out!
  10. Serve!

so sad because i was so looking forward to this but it never rose😩Going to see if maybe baking powder was expired

I have been baking for a long time and this cake was not even the yellow color. It did not rise and looks nothing like the cake in the recipe. So weird. It tastes very good but it is Brown not yellow .

I made this yesterday and it is delicious! Today I poured some sugar free chocolate syrup over it and it was glorious. I could taste the almond flour a little bit. Do you have a brand you recommend? Thanks for the awesome recipe!

I just made this cake a few hours ago. Maybe I measured the baking powder wrong or something because it didn’t rise like a normal bunt cake. Also, the texture was really horrible with the almond flour. What can I do differently next time? Should I have mixed the ingredients a certain way? I’m not new to baking but this was my first keto baking. The taste of the cake was great and I made a keto chocolate buttercream icing to put on top.

hi! your baking powder may have been expired or gone bad. That is probably why it didn’t rise and had a bad texture. No specific way to mix the ingredients so it should be fine any way. Do a test with your baking powder. Add some water to 1 tsp of baking powder, it should violently bubble up. If it doesn’t or its more of a subtle bubble, your baking powder has probably gone bad. I also recommend adding in maybe a scoop of protein powder – that will help with the lift and give it more of a fluffier texture.

My family is from Kentucky so it’s gotta be good from the south ya know! And it’s got BUTTER!! You being from Canada, I appreciate a Kentucky style recipe from ya’ll up north. Thanks. I’ll have to put this one in my file.

Hey Linda! I’ve actually done that! Here is the link to that recipe: https://wp.me/p6Yuzo-F4

You can still bake it in a bundt pan and add the syrup!

Any keto recipes I have baked have been crumbly. Does this cake stay in a solid piece when cut? Have you ever used xantham gum? Thanks!

Reply
hungryelephant December 29, 2018 - 9:06 am

Yes it’s definitely not crumbly. I’ve used xanthan gum before and you could add a tsp in here to hold it together 🙂

Jennifer December 31, 2018 - 7:05 pm

I made this cake as 12 mini bundt cupcakes. I followed the recipe exactly but only cooked them for about 29 minutes. They came out perfect! Thank you for a wonderful recipe. Next time I think I’ll add some rum to the glaze. Or just soak these in some now!

Reply
Lacie January 5, 2019 - 8:19 pm

I accidentally only added half a cup of butter to the batter and only did softened (I should have watched the video first!) How badly do you think I ruined it? My batter was pretty thick

Reply
Leena January 6, 2019 - 11:06 pm

Made this today and loved it! So soft, moist and delicious! Tad too sweet though. So next time would prefer to either not use swerve in the butter syrup or cut the swerve in half in the cake itself. Very yummy though. Thanks for sharing the recipe.

sue January 10, 2019 - 12:51 pm

Please…..what size is your cake pan? Either capacity or inches? You say “packed” almond flour. Are you packing it hard like brown sugar? Most recipes say to lightly scoop the flour — I want to do it right for this recipe. thank you

Reply
hungryelephant January 10, 2019 - 2:55 pm

Yes, like brown sugar 🙂 as for the bundt pan, I’d say it’s 9inches across!

A family member had a rum cake shipped to us from Kilgore, Texas this Christmas. I was devastated being four months into lowcarb and having lost three sizes. I had to give it away! It looked an awful lot like this! I’m going to try this with just a little bit of rum in the syrup. If I’m not mistaken, rum is allowed on keto, right?

Pablo January 24, 2019 - 8:13 pm

I followed this recipe exactly (by weight) and batter came out super thick, almost like cookie dough. Any idea why? My eggs were big, I measured and double checked everything, it should’ve worked… I tried fixing it by adding more cream and butter and a little water, but I’m worried about how it’ll come out, it’s in the oven right now

Reply
hungryelephant January 24, 2019 - 3:21 pm

I’ve had some people say this although I’m not sure why. Might be the almond flour brand? Either way, see how it is after the oven. Most of them turn out well despite being thick. Let me know!

Sugar substitute… granulated or like powdered sugar?

if it just says sugar substitute, I always mean granulated. I will always specify if needed icing/confectioners/powdered sugar substitute.

Kristin February 2, 2019 - 5:12 pm

Anyone new to baking will likely run into issues with this recipe, as it leaves out some basics. First, you have to prep your baking pan with butter and a dusting of almond flour so the cake doesn’t stick. Bring the butter to room temp. Use a mixer. First, cream the butter and sweetener. Then add the sour cream and mix until combined. Add the eggs one at a time, mixing until each is combined. Add the vanilla, then the dry ingredients and mix again until it’s all combined into a batter. Thanks for this delicious recipe!

I beg to disagree. , You dont need to cream the butter etc., , I made it like a DUMP CAKE. all the ingredients in one bowl .
CAME OUT SPECTACULARLY !!

Reply
Joy February 9, 2019 - 6:09 pm

I tried this today and it was pretty good. I am new to keto and I’m missing regular flour a lot. Most of the things I’ve made with almond flour just don’t cut it. I think the difference with this recipe was poking the holes and pouring the butter mixture in made it more moist than anything else I’ve had and so I enjoyed it better. One thing I did differently was I had some xylitol sweetener that I had mixed with some cinnamon for something else and since I didn’t want to throw it away I used that. The cinnamon was a really nice touch.

Reply
Joy February 9, 2019 - 6:17 pm

(The cinnamon was in the syrup not the cake)

I made this in a rectangular pan (don’t have a bunt pan), and it turned out so yummy!
With the last piece I had I decided to add low sugar jam and peanut butter and omg, delicious!!
Do you think I can make a layered cake by making two cakes in my rectangular pan and adding strawberries and whipped cream between the layer and on top? Wondering if it’ll be too sweet and how I should tone down the sweetness. Not adding the syrup? Or will that change the taste of the cake too much?!
Thank you!!!

This was SO good. My husband loves all things lime so I changed it up only a bit. I added lime juice and zest to the batter and replaced the water in the sauce with lime juice (until it tasted lime-y enough!). Topped with swerve confectioners sugar and lime zest. PERFECT. Thank you!

Cheryl May 11, 2019 - 11:41 pm

This is a winner recipe, but in your directions, you could clarify what size (cup capacity) bundt pan you used. My cake was about 1/2 the size (in rise) that is should be. Next time I would double this recipe. The butter syrup takes this over the top great! I am serving this for Mother’s Day tomorrow, with strawberries and a smidge of chocolate buttercream piped along the bottom edge. Also emphasize buttering or spraying the bundt pan- I sprayed mine with coconut oil, but will use MORE next time…. Yes… there will be a next time!!

Hi there! First of all…AMAZING recipe! I made this for a friend doing Keto and he cannot stop raving about it! Such being, he actually wants me to bring 2 of them to his house! My only issue is…I only have 1 bundt pan and not enough time! Do you think this can be made in a sheet pan, and if so, what size/time would work best? Thank you so much!

Reply
hungryelephant May 14, 2019 - 4:47 pm

Yes it should be fine! I’d probably do it at 30 minutes and check from there. An average size one would be best. 21×15?

Chelsey Urianza May 14, 2019 - 4:51 pm

Wait what….a 21×15? I don’t have a 21×15! I have a 9×13? 11×7? 12×8? Anything?! Haha

I just thought I’d follow up and let you know that I baked this recipe in a 12×10 (half steam table tray), poked/poured as normal, cooled, then dusted with Swerve powdered sugar…STILL just as perfect! My keto friend said he devoured 4 pieces as soon as he got home! Thank you so much– this one is def a keeper (:

hungryelephant May 17, 2019 - 2:49 pm

Yay! so glad to hear! 🙂

Shannon July 3, 2019 - 6:14 pm

I followed the recipe to a tee and had a separate thermometer to check the oven temperature, but it was still uncooked after 35 minutes. I put it in for an extra 5 minutes, but it still seemed undone. I was hoping it might set as it sat out, but nope. When I tried to flip it out of the binder cake pan, it came out as a broken up mess. If you think it needs more time, I recommend going with your gut.

hey trina! it sounds like the baking powder was an issue. I realize you said it’s not expired, however baking powder can go bad quite easily and if it’s been opened for sometime, it can lose it’s power while not actually expired. hope that helps!

I just opened my baking powder so not sure it was that but mine didn’t rise either. I also watched the video afterwards. I think the order you added the ingredients mattered. Would suggest altering the recipe to match the video. I just combined everything like the recipe says and could tell from the batter it would be a mealy texture.
