These easy keto blondies are heavenly! They are super moist and fudgy - and require only five minutes of prep.
This keto blondies recipe deserves a place in the hall of fame for sugar free desserts. It is that good!
I'm a huge fan of easy baking, and these blondies tick all the boxes:
- Staple kitchen pantry ingredients
- no special equipment needed (one bowl and a fork, that's it!)
- ready in 25 minutes
- 2.3g net carbs per square
And the taste! Ultra buttery and oozing peanut butter flavour, studded with chocolate chips... I'm salivating all over again.
In a nutshell, keto blondies are the blonde counterpart to my fabulously fudgy keto brownies. They are equally irresistible!
Ingredients
Here are the ingredients I used:
- Peanut Butter - I used smooth peanut butter. It must be nice and soft. You don't want the last hard dregs from the bottom of the pot. Ideally, choose a brand that contains just 1 ingredient - peanuts.
- Almond Flour - I use ground almonds in most of my recipes, this one included. Super-fine almond flour works equally well.
- Butter - melted and cooled. My butter was unsalted, but salted butter would give an interesting flavor lift.
- Eggs - Large, room temperature eggs is the way to go.
- Sweetener - I used a granulated monk fruit erythritol mix in this recipe. A golden erythritol would also be great here. You can replace the erythritol with either xylitol or allulose, which would make the blondies even softer.
- Baking Powder
- Vanilla Extract
- Sugar Free Chocolate Chips - A popular brand is Lily's. I simply made my own using 90% Lindt chocolate. I melted the chocolate and then poured it into a pyramid silicone baking mat. Or, make sugar free chocolate chips from scratch!

Instructions
Let's make easy keto blondies! Here are the basic steps.
You begin by lining a baking pan (mine measured 8 x 6 inches) with parchment paper. Also, preheat the oven.
STEP 1
Melt the butter (1 minute on high in the microwave). Then, add all ingredients except the chocolate chips to a large mixing bowl.
STEP 2
Stir with a fork until you have a smooth batter. Then, fold in the chocolate chips, holding some back to scatter over the top.
STEP 3
Fill the blondie batter into a prepared dish and scatter the remaining chocolate chips over the top.
STEP 4
Bake the blondies in the preheated oven for 20 minutes. After that, the top was golden and set, but the middle was still jiggly, a bit like a baked cheesecake.
It looked like this:
Expert Tips
#1 Always taste the batter before baking and adjust the sweetener. I don't have much of a sweet tooth, so you may prefer it a little sweeter!
#2 Don't over-bake low carb blondies! You WANT them to be slightly under-baked and on the fudgy side. That's how they taste best.
#3 Let them cool fully before cutting! They are very soft when hot and firm up as they cool.
Variations
Use different nut butter: Even though these are keto peanut butter blondies, you can replace the peanut butter with any nut butter of your choice, such as almond butter.
Dairy-free blondies: Replace the butter with coconut oil.
Nut free blondies: My go-to nut-free replacement for almond flour is a 50-50 blend of sunflower seed flour and sesame seed flour.
Coconut flour blondies - I have not tested this yet, but here is my suggestion: Replace the almond flour with â…“ cup / 40g coconut flour and add an additional egg. Coconut flour bakes up more brittle than almond flour and I think it will need the additional binder. Or, try my recipe for coconut blondies.
Storage
Store keto blondies in an airtight container at room temperature for up to 3 days or in the fridge for up to 1 week.
Alternatively, freeze them for up to 6 months. I always slice them before freezing, so I can defrost one square at a time.
