This low carb and Keto coffee cake has a tart sweet rhubarb layer and a streusel crumb topping. It's a wonderful summertime dessert with just 5g net carbs.
Greetings fellow rhubarb lovers!
I've been taste-testing rhubarb sauce all morning, and boy is my mouth tired! Rhubarb is ridiculously sour on its own, so I've been adding a little more sweetener, testing it, puckering up my mouth because it is so sour, and then starting the process again. The reason for all this experimentation is that, like lemon recipes, it's very easy to make rhubarb either too sweet or too sour.
Nevertheless I persisted, as they say.
But let me back up for a minute. If you have searched for and found this recipe, then you are likely familiar with the wonders of rhubarb. But for the rhubarb newbies out there: rhubarb is a cultivated perennial plant with red and green stalks and large (poisonous!) leaves.
Rhubarb is usually sugared up and used in desserts as though it is a fruit, but it’s technically a low carb vegetable. But to confuse things even more, a 1947 court opinion deemed the plant a fruit since it's often used that way. So you really have your pick in terms of what you call a nice hot pink stalk of rhubarb. I prefer to think of it as "sour celery".
So let's talk about the Keto Rhubarb Coffee Cake that we can make with this wonderfully tart plant.
Over the years, I've shared low carb recipes for Strawberry Rhubarb Cobbler, and my personal favorite, Rhubarb Cobbler Ice Cream. And today's recipe for Keto Rhubarb Coffee Cake fits right in. It's a simple vanilla coffee cake, topped by a tart and sweet rhubarb sauce and then sprinkled with a streusel crumb topping. It is a truly fabulous dessert.
Just promise me that you won't go rhubarb crazy and make yourself a suit out of rhubarb leaves.
Have a little dignity.

Absolutely the best low carb dessert I have ever made!!!! SO GOOD. The only thing I did differently was to use softened butter instead of melted.

Aren’t you so glad rhubarb is in season?
Rhonda Hagen says
Wow! Just wow! Can’t believe this is low carb... so yummy! I used half sweetener as I substituted with truvia and I also substituted almonds in topping for walnuts. Definitely will be making this again!
EmilyKrill says
Yay! So glad you like the cake.
Connie says
Very good! I used softened butter for the topping. Going to make next time with strawberries, think it would taste a lot like a strawberry shortcake!!

Have made this recipe several times and reminds me of German style „ Streusel Kuchen“. Today I am making it with a compote of redcurrants and raspberries instead of the rhubarb. The crumb topping is very soft and buttery so next time will just soften rather than melt the butter and rub it into the almond flour and sweetener( Monkfruit Brown) with a 1/2 tsp of cinnamon added. I add whatever nuts I have in the kitchen such as pecan, hazelnut , today the almonds and is always good. It is a bit of a multistep process. but as it is not a frequent treat is totally worth it! Thanks for the recipe. .

What a great low carb summer dessert option. I love that there is only 5 grams of carbs in this rhubarb coffee cake.

Yep, rhubarb is a very low carb vegetable/fruit. It's only got 4g net carbs per cup.

This looks INCREDIBLE! Two of my favorite things - rhubarb and coffee cake, in one! Thanks for the recipe!
EmilyKrill says
Sure thing! I love both things too.

Rhubarb! I just love it. But I've never had it in coffee cake. This looks amazing!
EmilyKrill says
Thanks!
Barbara says
I’m about to try the Rhubarb Coffee cake, but we’re is the coffee in the ingredients . Thank you
EmilyKrill says
No, there is no coffee in this coffee cake, but I can see the confusion. This is a cake that is served with coffee. Some people call it a crumb cake because of the streusel topping, but it is equally known as coffee cake.
