Almost every chocolate milkshake recipe I've seen calls for just three ingredients - Hershey's chocolate syrup, vanilla ice cream, and milk. Mine has a few more ingredients, but we're not reinventing the wheel here. Instead we are elevating our chocolate milkshakes with a simple 1-minute homemade chocolate sauce that really boosts the chocolate flavor.

Our secret to creating the best chocolate milkshake of your life is using dutch processed cocoa powder. It packs a much more chocolatey punch and the flavor of the chocolate sauce is much deeper and richer than using plain Hershey's syrup.

What You'll Need

Scroll down to the recipe card below this post for ingredient quantities and full instructions.

  • Dutch Processed Cocoa Powder - This type of cocoa powder gives a darker, smoother, less bitter taste than natural unsweetened cocoa powder, which makes it perfect for chocolate milkshakes.
  • Granulated Sugar - For just the right amount of sweetness to balance the cocoa powder so the chocolate sauce isn't bitter.
  • Water - Provides the liquid for the base of the homemade chocolate sauce.
  • Ice Cream - Use your favorite vanilla ice cream. For an even MORE chocolatey shake you can use chocolate ice cream.
  • Milk - Whole milk gives the best results for milkshakes, but you can even get away with nonfat if that's what you have in the fridge at home.

How to Make This Recipe

  1. Make the chocolate sauce. Combine the sugar, cocoa powder, and water in a microwave-safe bowl by whisking well. Microwave for 30 seconds, give it a good stir, then microwave for another 30 seconds until bubbling. It will be thin but will thicken a bit as it cools.
  2. Blend. Once your chocolate sauce has cooled, combine ice cream, chocolate sauce, and milk in a large blender. I recommend starting with less milk and only adding more as needed until you get the shake consistency that you like best. Blend on medium speed, stopping to scrape the sides of the blender pitcher so everything gets evenly mixed. If you want a thinner milkshake, adding a little more milk or blend longer. If you want a thicker milkshake, you can add another scoop or two of ice cream.

Let the homemade chocolate sauce cool before using it in your chocolate shakes or they will likely turn out runnier than you want them to be because the hot sauce will start to melt the ice cream.

  1. Pour and serve. Divide the milkshake between two tall milkshake glasses and top with a generous swirl of whipped cream. We like to drizzle ours with a little of the reserved chocolate sauce, but you could also use chocolate sprinkles, mini chocolate chips, or a maraschino cherry on top!

Recipe FAQ's

How much chocolate sauce does this recipe make?

This recipe makes about ⅔ cup chocolate sauce, which makes for an intensely chocolatey shake. I like to set aside 1-2 tablespoons for drizzling over the milkshakes, and the milkshake is still plenty chocolatey.
