What does it taste like?

This peanut butter latte starts with the bold richness of freshly brewed espresso, balanced by creamy milk for a smooth, mellow base. Then comes the star: a silky, house-made peanut butter syrup that adds warm notes of roasted nuttiness and caramelized brown sugar sweetness. The result is a drink that’s nutty, slightly toasty, and just sweet enough — like sipping a peanut butter on a peanut butter cookie dunked in a creamy iced latte!

Why You’ll Love This Iced Coffee Recipe

• New, Yet Nostalgic - I’ve only recently started adding peanut butter to my coffee, and I’ve gotta say—I can’t believe it took me this long! If you loved peanut butter sandwiches as a kid, you’re going to love this peanut butter latte.
• Salty-Sweet - The homemade coffee syrup we use to sweeten our latte has the salty nuttiness of peanut butter and the carmelly sweetness of brown sugar, lending a creamy, crave-worthy flavor profile to your iced coffee.
• Cheaper Than A Café - It’s pretty much impossible to leave a coffee shop without spending at least $5 these days. But when you don the barista cap at home, you can get all the flavor for a fraction of the price—all without waiting in line.

Ingredients Needed

• Peanut Butter Coffee Syrup - While you’re welcome to use store-bought coffee syrup, my homemade version is a snap to make with just water, brown sugar, and creamy peanut butter. 
• Espresso - The concentrated coffee flavor of espresso helps balance out the peanut buttery sweetness of the syrup.
• 2% Milk - Since my peanut butter syrup is made with real peanut butter, this iced latte is already quite rich. Using 2% milk helps keep the fat and calories at more reasonable levels while ensuring you still get a creamy mouthfeel.

Substitutions

• Peanut Butter Coffee Syrup - Iced lattes can be made with any flavor of coffee syrup you like! The ratio pretty much stays the same no matter what.
• Espresso - Feel free to swap in 8 ounces of conventional coffee that has been chilled, or make peanut butter cold brew coffee instead.
• 2% Milk - You’re welcome to use any percentage of dairy milk or any variety of plain or vanilla-flavored plant-based milk you like.

How To Make An Iced Peanut Butter Latte

This speedy recipe comes together in just a few simple steps: 

Step 1: Add the peanut butter syrup to a glass of ice.

Step 2: Pour the espresso on top. Stir it a bit to combine.

Step 3: Top with cold milk and enjoy! (Feel free to froth the milk a bit first if you like.)

Optional Variations & Dietary Adjustments

• Sugar-Free - Simply swap in the cup-for-cup brown sugar alternative of your choice when you make the peanut butter syrup, or buy a pre-made one at the store. (If you’re using plant-based milk, make sure to read your labels—most have at least a little added sugar.)
• Vegan/Dairy-Free - Easily make a vegan version of this yummy iced coffee by using the plant-based milk of your choice. I recommend reaching for a “barista blend” whenever you’re going vegan—they’re specifically formulated to have a nice, thick consistency.  
• Peanut Butter Cup Latte - The only thing better than peanut butter is peanut butter and chocolate. Add some Reese’s inspired goodness to your cup by using just half the syrup that’s called for and replacing the other half with mocha syrup ~or~ use your favorite chocolate milk and slightly reduce the amount of syrup you add to keep the latte from being too sweet.

Serving Suggestions

There’s more than one way to enjoy this iced peanut butter latte! Here are some delicious ideas to get you started:

• Terrific Toppers - Add a dollop of whipped cream or some sweet cream cold foam and drizzle the top with extra peanut butter syrup for an extra indulgent treat. (Or use chocolate cream cold foam for more of a peanut butter cup vibe, or salted caramel cream cold foam to double down on the salty-sweet theme.)
• Special Sauce - Drizzle a bit of peanut butter syrup and/or chocolate syrup in a clear serving glass before assembling your latte for an impressive presentation. Don’t be precious about it—a random pattern is just as pretty!
• Sweet Pairing - Since this iced peanut butter latte is pretty sweet, I like to pair it with a high-fiber and/or high-protein snack. Think strawberry chia jam on whole grain toast, high-protein strawberry overnight oats, or a chocolate chip protein muffin.

Recipe Success Tips

• Chill your glass. Pop your glass in the freezer for a few minutes before assembling for an extra-cold and refreshing experience.
• Adjust sweetness to taste. The peanut butter syrup is naturally sweet from the brown sugar, so you can use less (or more!) depending on your preference.
  Use creamy peanut butter. Smooth, shelf-stable peanut butter blends into the simple syrup best. Natural or crunchy varieties can separate or leave bits behind.
• Shake it up for extra froth. Want a foamy top without a milk frother? Add everything to a sealed jar or cocktail shaker with ice and shake vigorously before pouring over fresh ice.
• Make the syrup ahead. The peanut butter syrup keeps well in the fridge for up to a week, so you can whip up peanut butter lattes in no time—all week long.

Homemade Peanut Butter Latte Nutrition

At 317 calories per serving, this iced peanut butter latte is a bit of a treat. But, with 11 grams of protein and 14 grams of fat (thanks to the peanut butter and milk), it also brings some staying power making it more satisfying than most coffeeshop drinks.

The 39 grams of carbohydrates include 35 grams of sugar, mostly from the homemade peanut butter syrup. While it’s definitely a sometimes-treat, the fat and protein help slow the absorption of those sugars, which may help avoid a major blood sugar spike. For added protection, pair it with a high-fiber snack.

If you're looking to lighten it up in terms of fat, calories, or sugar, consider using a lower-fat milk, halving the syrup, or trying a sugar substitute like monkfruit or stevia in your syrup. Either way, it’s a fun, indulgent drink that offers a little nutritional bonus from the protein-packed peanut butter. Enjoy every sip—just do it in moderation.
