Five Guys-Style Peanut Butter Milkshake

The Sunday my youngest came home from college declaring she had discovered the perfect milkshake at Five Guys, I knew I had to reverse-engineer it. We stood in the kitchen that evening taking turns blending different ratios until spoons stood straight up in our glasses. Now this version lives in permanent rotation, especially during those humid summer afternoons when nothing satisfies like something cold, sweet, and decadent.

Last summer I made these for my daughters birthday party and the adults kept sneaking back to the blender for seconds. The best part is how quickly they come together, so when someone unexpected drops by you can have restaurant-worthy shakes in minutes flat.

Ingredients

• Vanilla ice cream: Premium, full-fat versions create that luxuriously thick texture milkshake lovers demand, so skip the light stuff here
• Whole milk: Cold milk helps control consistency while keeping things creamy and rich
• Creamy peanut butter: Unsweetened or lightly sweetened varieties give you control over the sugar level while delivering authentic peanut flavor
• Vanilla extract: This small addition rounds out the flavors and makes everything taste more cohesive

Instructions

Blend it all together:

Add your ice cream, milk, peanut butter, and vanilla to a blender and let it run on high for about 30 to 45 seconds until completely smooth and velvety.

Check your consistency:

Dip a spoon in to test thickness, then blend in extra milk if you prefer it thinner or add a scoop more ice cream if you want that stand-up straw experience.

Pour and serve:

Cold glasses make all the difference here, so stick them in the freezer for at least 10 minutes before pouring your shakes to the rim.

Save

These shakes have become our family go-to for celebrating small victories. Nothing beats the sound of spoons clinking against glasses as everyone digs in at the same time.

Making It Vegan

Plant-based ice creams have improved dramatically, and oat or almond milk blends beautifully with peanut butter for a dairy-free version that still delivers satisfying creaminess.

Storage And Timing

Milkshakes do not wait for anyone, so plan to serve them immediately. You can prep ingredients ahead by measuring everything into the blender jar, but do not blend until you are ready to drink.

Toppings That Transform

Whipped cream and crushed peanuts recreate the diner experience, but a drizzle of chocolate syrup blended right into the shake takes it over the top.

• Chill your glasses in the freezer for at least 10 minutes before serving
• Use long straws and sturdy spoons for the full experience
• Make extra because people always ask for seconds

Save

Grab your favorite glass and a couple of straws, then settle in for something sweet, rich, and completely satisfying.

Questions & Answers

→ How do I make the shake thicker?

Add more ice cream and reduce the milk quantity. For an extra thick consistency, freeze your glasses beforehand or blend in a few ice cubes.

→ Can I use natural peanut butter?

Yes, natural peanut butter works well and provides a more robust peanut flavor with less sweetness. Stir thoroughly before measuring to incorporate any separated oils.

→ Is this milkshake suitable for vegans?

Absolutely. Substitute dairy ice cream with your favorite plant-based alternative and use oat, almond, or soy milk instead of whole milk.

→ What's the best way to blend this?

Start on low speed to break up the ice cream, then increase to high for 30–45 seconds. Stop occasionally to scrape down sides and ensure everything is fully incorporated.

→ Can I make this ahead of time?

For best texture, serve immediately after blending. If you must prepare ahead, blend and freeze in an airtight container, then give it a quick stir before serving.

→ What toppings work best?

Whipped cream, crushed roasted peanuts, and chocolate syrup are classic choices. Try chopped peanut butter cups, banana slices, or a drizzle of caramel for variety.
