Iced Coffee Mix

Three ingredients shaken in a mason jar. That’s the whole project. Instant coffee granules, powdered creamer, and granulated sugar — combined, sealed, and ready to make iced coffee in about 90 seconds whenever you want it. No brewing, no waiting, no drive-thru line, no $6 receipt.

The jar makes roughly 20 servings. You make it once and it sits on the shelf for up to six months, which means the question of what to do about iced coffee is already answered every morning without any decision-making involved. That’s the actual value of a pantry mix — not the cost savings, though those are real, but the fact that the default changes. The jar is there. The habit is easier.

What’s in the Jar

Instant coffee granules are the base — they dissolve in hot water in seconds, which is what makes this mix fast. The quality of the instant coffee matters more here than in a recipe where other flavors are carrying the load. A good instant coffee like Café Bustelo instant, Folgers Classic Roast, or Nescafé Gold produces a noticeably better cup than a bargain brand. It’s a small investment for 20 servings.

Powdered coffee creamer does two jobs: it adds creaminess and it carries the sweetness. Regular dairy powdered creamer, coconut creamer, or oat milk creamer all work — use whatever you normally add to your coffee. The powdered format means it stays shelf-stable and blends evenly through the mix rather than settling at the bottom.

Granulated sugar sweetens the base. The recipe uses half a cup for 20 servings — about a teaspoon per drink — which is lightly sweet. Adjust up if you want a sweeter cup, down if you don’t. Sugar substitutes work at the same ratio.

How to Make the Iced Coffee

Add 2 to 3 tablespoons of mix to half a cup of hot water. Stir until completely dissolved — the mix needs hot water to dissolve properly, which is why you don’t just shake it into cold water. Pour over a full glass of ice. Add cold water or cold milk to fill the glass and adjust to the strength and creaminess you want.

The hot-water-first step is what keeps this from tasting weak. Dissolving the mix in a concentrated half cup of hot liquid before adding ice means you’re not diluting it before the coffee is even properly made. The ice dilutes it to the right strength as you drink.

Adjusting the Strength

Two tablespoons per serving produces a mild, lightly caffeinated iced coffee. Three tablespoons produces something closer to a medium coffee shop strength. For a stronger cup — closer to an iced Americano — use three tablespoons of mix and only a quarter cup of hot water, then pour over ice and top with cold water only, no milk.

The mix is fully customizable batch to batch. If you want it stronger overall, increase the coffee-to-creamer ratio in the jar. More coffee, same creamer, same sugar. The jar doesn’t lock you into one strength forever.

Flavor Variations

All of these go directly into the jar when you make the mix — no extra steps at serving time.

Vanilla latte: add one tablespoon of Vanilla sugar — thisoldbaker.com/vanilla-sugar or vanilla bean powder to the jar. The vanilla distributes through every serving without measuring anything extra each morning.

Mocha: replace two tablespoons of the powdered creamer with Dutch-process cocoa powder. The cocoa dissolves into the mix and turns every cup into a chocolate coffee drink.

Cinnamon roll: add one teaspoon of ground cinnamon to the jar. It adds warmth without sweetness and pairs well with the vanilla variation.

Low sugar: reduce the granulated sugar to a quarter cup or swap for allulose or a monk fruit blend at the same ratio.

Dairy-free: use coconut milk powder or oat milk powder in place of the regular powdered creamer. Either produces a creamy result with a slightly different flavor note — coconut adds a mild tropical undertone, oat milk is more neutral.

Adding Simple Syrups at Serving

The dry mix handles the base sweetness. For flavored drinks that go beyond what’s in the jar, a pump of homemade simple syrup added at serving time is the move. A tablespoon of Vanilla Simple Syrup — thisoldbaker.com/vanilla-simple-syrup turns this into a vanilla iced coffee. Raspberry syrup makes it a raspberry iced coffee that genuinely competes with anything on a coffee shop menu. Hazelnut, toffee, caramel — the Homemade Simple Syrups collection — thisoldbaker.com/homemade-simple-syrups gives you six flavor options to rotate through without buying anything extra.

If You Want to Go Further

This mix is the fastest possible iced coffee. If you want the version with deeper, richer coffee flavor and no instant coffee involved, my Cold Brew Coffee Concentrate — thisoldbaker.com/cold-brew-coffee-concentrate-easy-overnight-recipe is the overnight approach — 12 hours of steeping, no heat required, and a concentrate that keeps in the refrigerator for two weeks. Both have a place in a practical kitchen. The mix is for weekday mornings. The cold brew is for when you planned ahead.

Gifting

A pint jar of this mix with a tag that lists the use ratio (2-3 tablespoons mix + half cup hot water, pour over ice) is one of the most practical pantry gifts you can make. Pair with a jar of vanilla simple syrup or hazelnut simple syrup for a two-jar coffee gift set that covers a month of iced coffees.

Storage

Sealed pint mason jar in a cool dry pantry for up to 6 months. Keep it away from heat and steam — the powdered creamer can clump in humidity. If the jar clumps, shake or break it up before measuring; the flavor isn’t affected. Label the jar with the date you made it and the use ratio so it’s ready to use without hunting for the recipe.
