Peanut butter has always been one of those flavors I could eat in any form. Straight from the spoon, baked into cookies, or blended into the creamiest milkshake you've ever tasted. Growing up in Florida, our summers were hot and our treats were homemade, and there is nothing better than blending up something cold and indulgent when the heat outside is doing the most. This peanut butter milkshake is the one I keep coming back to.

What I love most about this recipe is how honest it is. Three ingredients, five minutes, and a blender is all you need. No fancy technique, no hard-to-find ingredients, and no wondering if it'll turn out right. I've made this shake more times than I can count, tested different ratios, and landed on a version that is perfectly thick, perfectly creamy, and loaded with real peanut butter flavor in every single sip.

Whether you're making a treat for the kids on a hot afternoon or sneaking one for yourself after dinner (I see you), this is the recipe to reach for. Let's get started!

Why You'll Love This Peanut Butter Milkshake

• Only 3 ingredients - milk, vanilla ice cream, and peanut butter. That's it. No mystery pantry items required.
• Ready in 5 minutes - blend, pour, done. It's faster than driving to Dairy Queen, and honestly better.
• Perfectly thick and creamy - this shake is designed to be luxuriously thick, not watery. The ratio is tested and reliable.
• Endlessly customizable - chocolate version, banana version, dairy-free, no ice cream. There's a variation for everyone in the Variations section below.

Ingredients You'll Need

1. Whole milk is the base liquid here. Whole milk gives you the creamiest, richest result because the fat content works with the ice cream to create that classic milkshake texture. If you prefer a thinner shake, you can add a splash more milk after blending. For a dairy-free swap, extra-creamy oat milk is my favorite substitute, it behaves most like whole milk in texture and flavor.
2. Vanilla ice cream is what makes this a milkshake and not a smoothie. Use your favorite brand, but stick with plain vanilla, you want the peanut butter to be the star. Good vanilla ice cream has a clean, creamy base that lets the peanut butter flavor really shine through. For a dairy-free version, Oatly Non-Dairy Vanilla Dessert works beautifully. You can also use No Churn Vanilla Ice Cream if you have a batch on hand.
3. Creamy peanut butter is the heart of this recipe. Use a processed brand like Jif or Skippy for the smoothest, most consistent blend. Natural peanut butter works but can be oilier and may not blend as smoothly, if you use it, give it a good stir first. Avoid chunky peanut butter unless you love a little texture in your shake.

How to Make a Peanut Butter Milkshake

Step 1: Measure Your Ingredients

Start by measuring out your milk, ice cream, and peanut butter before anything goes in the blender. The key with ice cream is to pack it when you scoop, you want those scoops generous and full. If your ice cream is rock-solid from the freezer, let it sit on the counter for 5 to 10 minutes to soften slightly. This makes blending much easier and helps your shake come out smooth rather than lumpy.

Step 2: Add to the Blender in Order

Add the milk to the blender first, then the ice cream, then the peanut butter on top. Adding liquid first gives the blender blades something to work with right away and helps everything blend more evenly. If you put the ice cream in first, it can stick to the bottom of the blender and make it work harder than it needs to.

Step 3: Blend Until Smooth

Put the lid on tightly and blend on medium speed until everything is completely combined and smooth, usually about 30 to 45 seconds. Don't over-blend. The longer you run the blender, the warmer and thinner your milkshake becomes. Stop as soon as it looks smooth and pourable. If it's too thick, add a small splash of milk and pulse once or twice. If it's too thin, add a scoop of ice cream and blend again briefly.

Step 4: Pour and Serve Immediately

Pour straight into your serving glass and enjoy right away. Milkshakes are always best fresh, within minutes of blending, before the ice cream starts to melt and the texture changes.

LaKita's Expert Tips

• Chill your glass first. Pop your serving glass in the freezer for 10 minutes while you gather your ingredients. A cold glass keeps the shake thick longer, especially if you're a slow sipper.
• Pack the ice cream when measuring. Don't be stingy, a loosely scooped cup of ice cream will give you a thinner shake than a well-packed one. Pack it in like you mean it.
• Let the ice cream soften just a little. 5 to 10 minutes on the counter is all it takes. This prevents the blender from struggling and ensures a lump-free result.
• Add milk last, not first, wait, actually: Add milk to the blender first so it hits the blades, then layer ice cream and peanut butter on top. This is the order that gives the smoothest blend.
• Don't over-blend. 30 to 45 seconds on medium speed is your target. Blending too long heats the mixture and breaks down the texture.
• Use a spoon to pack the peanut butter. Peanut butter likes to cling to measuring spoons. Spray the spoon lightly with cooking spray first, or just scoop generously and scrape clean, don't leave peanut butter behind in the measuring utensil.
• For a thicker shake: Use less milk, more ice cream, and consider popping the finished shake in the freezer for 10 minutes before serving.

Variations & Substitutions

• Chocolate peanut butter milkshake: Swap the vanilla ice cream for chocolate ice cream using the same amount. Top with whipped cream, chocolate chips, and a drizzle of chocolate syrup.
• Banana peanut butter milkshake: Add one frozen banana (broken into chunks) to the blender along with the other ingredients. The banana adds natural sweetness and a gorgeous thick texture.
• Dairy-free version: Use extra-creamy oat milk in place of whole milk and Oatly Non-Dairy Vanilla Dessert instead of ice cream. The result is surprisingly close to the original.
• Peanut butter milkshake without ice cream: Blend ½ frozen banana + 1 cup frozen cauliflower + 1 cup oat milk + 3 tablespoons peanut butter for a thick, creamy shake without any ice cream. It sounds surprising, but it works beautifully.
• Reese's-style milkshake: Add a handful of Reese's Pieces or a chopped Reese's cup to the blender along with your regular ingredients for a candy-shop spin.
• Extra-thick milkshake: Reduce the milk to 2 tablespoons and add an extra half-scoop of ice cream. Serve with a wide straw or a spoon.

Make-Ahead & Storage

Make-Ahead

This milkshake is best made and consumed fresh, that's the honest truth. The texture changes quickly as the ice cream melts, so I don't recommend blending it ahead of time. What you can do is measure out your ingredients ahead of time: pre-measure the peanut butter into a small dish and have your milk portioned, so when you're ready, the blender takes 60 seconds total.

Storage & Reheating

If you have leftover milkshake (which is rare, but it happens), pour it into a sealed container and store it in the freezer for up to 24 hours, not the refrigerator. In the fridge, it turns into a melted, watery mess. In the freezer, it holds better. To serve from frozen, let it thaw on the counter for 10 to 15 minutes, then stir or blend briefly on low speed for 15 seconds to bring the texture back. It won't be quite as fresh as the original, but it's still good.

What to Serve with a Peanut Butter Milkshake

• As a dessert pairing - it goes beautifully alongside White Chocolate Peanut Butter Cups for a full peanut butter moment.
• With a scoop of homemade ice cream on the side - try it with No Churn Vanilla Ice Cream for a full ice cream bar experience at home.
• As a drink alongside something salty - the sweetness of the shake balances perfectly with salty snacks or a savory meal.
• On a summer afternoon with the Strawberry Smoothie - set up a DIY smoothie and shake bar for the kids, let everyone pick their flavor.
• For dessert after dinner - if you've made something rich and savory, a small shake glass is the perfect sweet finish.
