1Place your blender container in the freezer for 15 minutes before beginning to ensure maximum thickness in your finished shake.
2Scoop the premium vanilla ice cream into the chilled blender, allowing it to soften at room temperature for 2-3 minutes to facilitate easier blending without over-mixing.
3Pour the whole milk and heavy cream over the ice cream, adding gradually to control consistency.
4Add the malted milk powder, vanilla extract, and sugar directly into the blender.
5Pulse the mixture 3-4 times using short 2-second bursts to initially combine ingredients without over-aerating.
6Blend on low speed for 10-15 seconds only, just until ingredients incorporate into a thick, creamy consistency that's still spoonable.
7Check thickness by stopping the blender - the shake should slowly fall from a spoon rather than pour. Add 1-2 tablespoons additional milk if too thick, or 2-3 more tablespoons ice cream if too thin.
8Pour immediately into a chilled tall glass, filling to about ¾ inch from the rim.
9Top generously with whipped cream, creating a dome that rises above the glass rim for authentic restaurant presentation.
10Serve with a wide straw and long spoon for the complete Five Guys experience.
