Malt question: Horlick's vs. malt extract vs. Carnation

I love chocolate malts, and I always have to ask for EXTRA EXTRA malt in order to get enough of the delicious malt flavor I am looking for. Unfortunately, most places us Carnation Malted Milk powder, which I believe contains at least as much powdered milk as malt. It always seemed a little redundant to me to add milk powder to a milk shake.

I am on a quest to find the strongest pure malt flavor that I can without having to use a "malted milk" product. I found some online homebrew/beer stores that offer powdered malt extract, and I have seen a lot of recommendations for a product called Horlick's. I am wondering if anybody has any experience with or advice about what I should try? Is liquid malt extract more powerfully flavored than powdered? Is malt extract actually what I am looking for? Is Horlick's going to provide the strong flavor I am craving? Thanks in advance for any advice you can offer!
