Start by collecting all of your ingredients on the counter. This makes the process smoother and ensures you don't miss anything essential.

In a high-powered blender, add the vanilla bean ice cream and fresh whole milk. Next, sprinkle in the malted milk powder. Blend on high until you achieve a smooth, creamy consistency. Keep an eye on it; you want everything well mixed but avoid over-blending.

Now, drizzle your homemade chocolate sauce into the mixture. Don’t just plop it in. Instead, swirl your blender to ensure the chocolate marries with the vanilla shake without becoming one solid color. You want it mixed just enough to create a marbled look.

Once blended, pour the milkshake into tall glasses. For a fun presentation, add extra chocolate sauce to the insides of the glass before pouring in the shake. Top it off with whipped cream (if desired) and maybe a sprinkle of malt powder to amplify the experience.
