Can peanut butter coffee be consumed together? How to make a delicious peanut hot latte special?

A Peanut Inspiration

One morning, while shelling peanuts, FrontStreet Coffee had a thought: these are delicious — savory and aromatic. Could they go into coffee? And if so, how exactly?

Inspired, we searched online and found that others had already put peanuts into coffee. Plenty of menus feature peanut lattes, made in all sorts of ways. So today, let's take a close look at this rather special flavored coffee.

Gathering the Ingredients

From the recipes we found, one thing became clear: to get that rich peanut aroma into coffee, whole peanuts aren't the way to go — bread-spread peanut butter is. Strictly speaking, a "peanut latte" is really a "peanut butter latte." Peanut butter brings a natural salty-sweet, deeply nutty flavor in a light, smooth, creamy texture, and it pairs beautifully with milk coffee in both hot and cold drinks.

But peanut butter is primarily savory and high in fat, so simply stirring it into a latte can feel jarring — your palate may rebel after a few sips. That's why FrontStreet Coffee experimented with sweet elements: honey, condensed milk, syrup. Each adds layers to the drink and, to some extent, rounds off that "sauce-like" edge.

The other key ingredient — the coffee itself — matters just as much. To amplify the nuttiness, FrontStreet Coffee reached first for Brazil Cerrado, which naturally carries creamy peanut notes. This medium-dark roasted Red Bourbon is semi-washed processed, with balanced flavor, low acidity, and medium body. As espresso it produces good crema, and it works for moka pot and espresso machine extraction alike. It's also a regular component of FrontStreet Coffee's espresso blend.

Peanut Iced Latte

Step One

Take a clear coffee glass and scoop a spoonful of peanut butter, spreading it evenly on the inner walls.

Then add 100 grams of ice cubes and 180 grams of milk.

Step Two

Scoop 20 grams of peanut butter and 12 grams of condensed milk into a clean, wide-mouthed container. FrontStreet Coffee recommends a pourable peanut butter (skip the solid kind) — it blends with the other ingredients much faster when stirred.

Step Three

Extract two shots of espresso using the Brazil Cerrado beans. In our shop the espresso grinder is set to 2.0, with 20 grams of coffee extracted at a 1:2 ratio over 31 seconds to yield 40 grams of espresso.

Step Four

Pour the espresso over the peanut butter–condensed milk mixture and blend with an electric mixer until the foam turns creamy and all three ingredients are fully combined.

Final Step

Pour the blended peanut-butter coffee over the iced milk, and a fragrant peanut iced latte is done.

Give it a gentle stir and the faint peanut aroma is already there. Take a small sip through a straw and you'll taste creamy peanut, milk chocolate, and caramel biscuit notes in a velvety, smooth texture. The ice keeps the rich nuttiness in check with a hint of milky sweetness — never cloying. A genuinely excellent drink.

Peanut Butter Hot Latte

The hot version is built much like any hot milk coffee. The key questions are: without ruining integration (latte art) and flavor, how much of each sauce (peanut butter, condensed milk, etc.) to add — and where, and when.

Compared with the refreshing lift of iced coffee, hot drinks bring out an ingredient's inherent flavors more directly, and the milk adds a character reminiscent of salty cheese. So if you don't want the "sauce flavor" to dominate, trim the amounts slightly. Here FrontStreet Coffee reduced the peanut butter to 12 grams and used 6 grams of condensed milk.

On our first attempts, we tried to exploit the vortex and high temperature of milk steaming to "melt" the peanut butter and condensed milk, adding them to the milk before frothing. The results were disappointing, for two reasons: first, peanut butter doesn't dissolve easily in milk, which makes it hard to build silky microfoam, and the patterns won't hold. Second, peanut butter turns the milk "cloudy," and that darker color hurts latte art without buying anything in texture.

So on the second attempt we changed the plan: let the peanut butter meet the espresso first, and add the condensed milk to the milk instead. That solved the frothing problem and let the peanut flavor express itself fully in the coffee.

The resulting hot peanut latte is far more balanced. The crema on top contributes caramel and dark chocolate aromas; the first sip brings rich roasted peanut, lifted by lightly sweet hot milk into a creamy, smooth texture — much like biting into a peanut cocoa cookie.

Beyond the methods FrontStreet Coffee described, feel free to improvise to your own taste. Crushed nuts sprinkled on top boost both looks and texture; a touch of sea salt seasoning works nicely; and you can swap the milk base for oat milk if you like.

FrontStreet Coffee Recommendation

The secret to a great peanut latte is a bean whose own nuttiness does half the work. These Brazilian FrontStreet Coffee options are made for it:

FrontStreet Coffee Brazil Cerrado Red Bourbon — the bean used in this recipe. A classic Brazilian single origin from the Cerrado growing region, semi-washed processed and medium roasted: creamy peanut, toast, caramel, and hazelnut aromas in a rounded, low-acid cup with just a touch of bitterness. Works for pour-over, moka pot, espresso SOE, siphon, or French press — and as we saw above, it's a star in milk-based specials.

FrontStreet Coffee Brazil Fazenda Rainha (Queen Estate) Yellow Bourbon — from Mogiana near southern Minas, where fertile red volcanic soil feeds deeply aromatic beans. The rare Yellow Bourbon varietal (a mutation of Red Bourbon) gives a cleaner fruit character: pour-over, moka pot, or home espresso all reveal a sugarcane sweetness you won't find from other origins, alongside fruit and chocolate notes.

FrontStreet Coffee Espresso Blend Series — Brazil's low acidity and balance make it the backbone of many espresso recipes, and FrontStreet Coffee's Classic Blend (rich crema), Premium Blend (nut-forward), Dark Cocoa Blend, and Commercial Blend all contain Brazilian components. The Brazil content contributes chocolate and cream aromas plus a gentle sweet-sour-bitter harmony that stabilizes extraction — exactly what you want under milk in a signature latte.
