These decadent Keto Butter Rum Blondies are perfectly chewy and loaded with walnuts. Lightly sweet, richly buttery, and with a subtle hint of rum, these are the best Keto blondies I’ve ever had!
I had other keto recipes in the queue to post here first, but I made these keto butter rum blondies last week and I just couldn’t wait to share them!
I love a good blondie, but keto blondies I’ve had in the past never measured up to the real thing for me. I honestly didn’t even know if it was possible to get that buttery, chewy goodness right using keto friendly ingredients – so for the longest time I didn’t even bother to try.
I finally went for it though, and I’m thrilled to say that these keto butter rum blondies are everything you’ve been missing in a keto blondie recipe – and then some!
Delicious with a cup of coffee in the morning, or as a sweet ending to dinner, these low carb blondies are so good that I had to cut them in half, and then freeze them, to keep from eating them all in just a day or two. ?
Keto Butter Rum Blondies Recipe Notes
These keto butter rum blondies don’t actually contain any rum, though you could use the real thing if you wanted to. I chose to use a rum flavoring/extract because it achieved the flavor I wanted without adding a lot of extra liquid to the batter. Any brand will do, I used McCormick brand that I found in the baking aisle.
For my sweetener, I used Lakanto Golden, which helped give these keto blondies that warm, rich flavor that you can’t get with a white sweetener. Swerve brown, or any other brown sugar alternative should work similarly – though I can’t guarantee the exact results I had if you don’t use the Lakanto (not sponsored or affiliated with Lakanto in any way, this is just what I used.)
Finally, these keto blondies make use of psyllium husk powder, which gives them an authentic, chewy texture. You can omit it if you like, but you’ll end up with a harder, crumblier result, more like a cookie than a blondie. Not necessarily a bad thing, but nowhere near as good as trying the recipe as written!

Used banana extract because it’s what I had on hand and added 1/3c chocolate chips — yum!! Perfectly moist and delicious.

This was super crumbly, I even added an extra egg to try and make it less so. Half the blondies crumbled in the pan while cutting and were unusable.

Mellissa Sevigny says
There must have been a problem with your ingredients (almond flour too coarse maybe) or measurements – these should not be at all crumbly.
Anna says
Melissa, do you think you could please put metric equivalents for the ingredients in your recipes? I’m sure you realise that you have international readers. It really would make things so much easier. Many thanks.

I didn’t have any luck with this recipe. They were crumbly. Couldn’t pick up without it falling apart. I don’t know what I did wrong but I will try again maybe.
nikole says
despite being too greasy for my liking, it was very tasty! the net carb count is way off. even without using nuts , the plain almond flour alone in this recipe has 64grams of net carbs divided by 9( the serving suggestion) comes to 7.1 gm of net carbs per serving not counting the optional walnuts added carbs. thanks for sharing the recipe though it was delicious however I will have to toss the rest because of the net carb count not matching what you claimed.

Your math is way off.

Made these beauties tonight!! So delicious! I omitted the psyllium husk powder, added Lily’s sf choco chips, and only baked the blondies for 15 minutes. Gooey, chewy, and perfect!
