These deliciously moreish chocolate peanut butter brownies are low-carb, gluten and refined sugar-free. However, the real challenge is not to eat the whole lot!

You can’t beat a great chocolate brownie, but there are just so many recipes to choose from. However, if you are looking for a change from the traditional, these chocolate peanut butter brownies certainly won’t disappoint. Not only are they low carb, at under 3g per brownie, but they are gluten-free and by using artificial sweeteners, they are free of refined sugars as well!

The winning combination of chocolate and peanut butter is an absolute winner in this recipe. They are brilliant as a tasty afternoon snack or served with a big scoop of vanilla ice cream as a delicious dessert. I promise you they never hang around for long in my house.
However, if you aren’t a fan of peanut butter then why not try my other low carb brownie recipe, double chocolate brownies

These chocolate peanut butter brownies have an intense chocolatey kick, enough to satisfy any sweet craving, but also the nutty butter topping gives them that extra gooey, stick to the roof of your mouth edge, which just makes them so moreish. However, if you wanted to make them a nut-free treat, simply omit the peanut butter topping before cooking.
Note on sweeteners
For these chocolate peanut butter brownies, I suggest using a brown sugar replacement. I tend to use either Sukrin Gold or NKD living Erythritol Gold (affiliate link) as a substitute for brown sugar. Both work really well in this recipe as they have a slightly mellower flavour which works well with chocolate. I have also baked these using Xylitol and to be honest, they still taste wonderful.
In addition, instead of using vanilla essence, a staple for lots of bakes, I replaced this with sugar-free vanilla drops. I currently like the sugar free drops from MY Protein Flavdrops (affiliate link). Our taste preference in this house is a sucralose based drop, however, you can also use stevia-based drops if you prefer. However, if you only have vanilla essence then just use that!
Don’t be afraid to experiment with different sweeteners and the quantities in sweet recipes. It may take a few attempts to find your preference as we all have a different palate.

Diabetes Note
These really make a great sweet treat option. Because of the use of almond flour, sweeteners and good quality dark chocolate, the overall carb count is dramatically reduced.
We have found that making some switches in recipes to reduce the overall carb count has helped to avoid some of those dreaded blood glucose spikes.
Carb Counting
The overall carb count for a serving of these chocolate peanut butter brownies based on the ingredients we would count (chocolate and cocoa powder):
Dark Chocolate 85% = 150g – 33g of carbs
Unsweetened Cocoa Powder =70g – 8.7g of carbs
Now add all the carbs together – 33+8.7 = 41.7g
Finally divide this by the serving size, 15 – 41.7/15 = 2.8 g of carb per brownie
