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!
