Do I Need A Mixer For These Low Carb Brownies 

I used a mixer for the brownies but it is not something you have to have. You could very easily do a bowl with a spatula and whisk it up that way. You just want to ensure you really incorporate the batter and make sure it is mixed well. 

Could I Substitute Chocolate Chips in Brownies Recipe 

Sure, if you have a sugar free (keto-approved) chocolate bar. You could chop up the bar and then place it in the batter. It would be bigger chunks but would add a nice texture and flavor to your peanut butter low carb blondies.

Could I Use Nut Butter In Peanut Butter Blondies

I personally have not tried using the nut butter in this recipe. I would assume it would convert wonderfully. So you are more than welcome to give it a try. If you do I would love to hear what you chose and how it turned out. 

How To Know Low Carb Blondies Are Done 

You will see that the brownies slightly pull away from the edges of the pan. It will also get a slight golden brown texture. Then just take a toothpick and stick it in the center of the pan, and if it comes out clean you know the brownies are done. 

One thing is to watch your brownies close to ensure they don't overcook. If you overcook these low carb blondie brownies you will find that it becomes dry. So if you start smelling the brownies, it never hurts to peek and check to see if they are done.
