A treat for you
Grenade’s White Chocolate allows you to have a treat without feeling guilty, especially if you’re dieting or in a low carb diet. If you’ve been strict in your diet, go ahead and have a couple of these bars, you deserve it for all the effort you put in.

Soy, sucralose and sugar alcohols
Soy, sucralose and maltitol are three things I don’t like seeing in the ingredients. Soy is used in the crispy pieces for the crunchy oomph, and both sucralose and maltitol are used as sweeteners. Soy is an inferior source of protein and may put male’s testosterone at risk (1). As for sucralose and maltitol, these are both sugar alcohols. Maltitol has 75% of the sweeteness of sugar and 75% of the blood sugar impact of sugar. It’s advantage is having less calories than sugar. I’d prefer if xylitol and erythritol were the main sweeteners.

Taste: 8/10

White Chocolate Cookie is the fourth addition to Grenade’s Carb Killa. It’s a glorified milky bar. A milky bar packed with protein.

A real milky bar
It has a white chocolate coating that tastes like a real milky bar, with crunchy chocolate cookie flavoured crispy bits in, followed by a layer of sweet vanilla that acts as base.

Crunchy and soft
The white vanilla base tastes like white chocolate but with the softness of caramel, making this a weirdilicious white chocolate flavoured caramel. You can’t go wrong with a white chocolate caramel combination, and looks like Grenade nailed this one right.

Overall rating: 8/10

Grenade’s Carb Killa White Chocolate Cookie is a protein bar with a white chocolate coating with cookie crispy bits on top of a crumbly biscuit base.

Pros of White Chocolate Cookie
White chocolate cookie is a 60g protein bar with 215 calories, 22g protein, 8g fat and 2g of active carbs. It has great nutrititionals, so it won’t ruin your diet. It can be a good pre-workout and post-workout, or just eaten as a snack during the day.

Cons of White Chocolate Cookie
Soy is a poor source of protein and has anti-testosterone properties(1). This protein bar is sweetened with sucralose and maltitol. It would be better to use good sugar alcohols such as Erythritol (zero glycemic index and 0.2 cal/g) or Xylitol (good for your teeth, it’s an ingredient in toothpastes).

It’s still awesome
White choc cookie is a great addition to the Carb Killa line. A great tasting protein bar that will remind you of the milky way bars you had when you were younger.

  1. Hey John! Thanks for the review.

    Just FYI, the soy content is for the crispies only, not as a source of protein. The protein in Carb Killa bars is Milk Protein which is made up from Calcium Caseinate, Milk Protein Isolate and Whey Protein Isolate)

    Also, White Chocolate Cookie isn’t available in the US…yet, but will be soon!


    1. Hi Neal, you’re welcome, and thanks for your comment. It’s good to know soy content is used in crispies only (still, I don’t like soy no matter how small it’s in the bar). Apart from that, I completely agree, good sources of protein. It’s good to know, for a change, that our US buddies get them later than us… hehe :)

  2. Linda

    Great review. 100% sure im gonna test it soon :)
