Ingredients: 1 medium sweet apple (about 150 g before coring; washed and cut into small dice); 3/4 cup water (180 ml, for the syrup); 1/4 cup granulated sugar (50 g); 3 cups chilled brewed coffee (720 ml; ready to drink, not undiluted cold-brew concentrate); 4 tsp caramel coffee syrup (1 teaspoon per drink; choose a pourable syrup); 3 cups ice cubes (approximately, divided among four glasses); 1 cup cold oat milk (optional; up to 1/4 cup per drink)

A small batch of apple syrup gives this iced coffee its fruit flavor without requiring a flavored coffee blend. Simmer diced apple with sugar and water, drain gently, then stir a measured spoonful into chilled coffee with caramel syrup. The default drink is served without milk, which keeps the apple flavor easier to judge.

The recipe makes four drinks using coffee that is already brewed and chilled. The apple syrup should yield roughly 1/2 cup, but evaporation and straining will change the amount. Four drinks use 1/4 cup of syrup altogether; refrigerate any remainder. Cooling the brewed coffee is not included in the stated recipe time.

Recipe development note: This formulation has not been kitchen-tested. Preparation times are estimates; follow the texture checks and product instructions.

Choosing the apple, caramel and chilled coffee

Use a sweet, fragrant apple rather than a very tart one for the first batch. Leave the skin on if it is sound and well washed; remove the core and seeds. Cut the flesh into roughly 1/4-inch pieces so it softens within the short simmer.

Pourable caramel coffee syrup mixes into cold coffee more readily than a thick dessert sauce. Check the ingredients if you need to avoid dairy or other allergens. This recipe does not include making caramel from hot sugar.

Use ready-to-drink coffee. If your cold brew is a concentrate, dilute it according to the product instructions before measuring. A strongly flavored coffee can hide the apple, while a weak one can taste watery once the ice melts.

Making apple syrup and four iced coffees

Step 1: Dice the apple and dissolve the sugar

Wash the apple, remove its core and seeds, and dice the flesh. Put the water and sugar in a small saucepan over medium-low heat. Stir until the sugar dissolves, then add the apple pieces.

Step 2: Simmer the syrup gently

Bring the mixture to a gentle simmer. Lower the heat, partly cover and cook for about 10–12 minutes, stirring occasionally, until the apple softens. Keep some liquid in the pan and avoid boiling it down to a sticky glaze. Cooking times depend on the apple and pan.

Step 3: Drain and cool the apple syrup

Set a fine-mesh sieve over a heatproof jug. Carefully pour in the mixture and let it drain for about 5 minutes without pressing the apple. Leave the syrup to cool for about 10 minutes, using a shallow heatproof container if needed. Measure the yield. Reserve 1/4 cup for the four drinks and refrigerate the rest promptly.

Step 4: Measure the flavorings and assemble

For each drink, stir 1 tablespoon of cooled apple syrup and 1 teaspoon of caramel syrup into 3/4 cup of chilled coffee. Add about 3/4 cup of ice to a tall glass and pour in the flavored coffee. Taste before adding more syrup. If using oat milk, add up to 1/4 cup and stir. Repeat for the other glasses and serve immediately.

Balancing sweetness and avoiding a pulpy drink

Start with the measured amounts rather than pouring both syrups freely. Caramel can quickly cover the apple flavor. If that happens, use less caramel in the next glass; adding more apple syrup to an already sweet drink may only make it sweeter.

Pressing the apple through the sieve makes a sauce-like mixture with pulp. Let gravity do the draining for a cleaner drink. Some cloudiness is still possible with fruit syrup. If the chilled syrup is too thick, thin the portion you are using with a teaspoon of water, rather than reheating the whole jar.

Optional milk and other small adjustments

Oat milk is optional, and the drink can be served black. Apple acidity and different milk formulations may cause separation; test a small amount before mixing all four glasses. Add only a small pinch of cinnamon if you want spice, since it can obscure the apple. For a single drink, prepare the syrup batch as written and use 3/4 cup coffee, 1 tablespoon apple syrup and 1 teaspoon caramel syrup. Keep the unused syrup refrigerated.

Keeping leftover apple syrup refrigerated

Refrigerate unused apple syrup promptly in a clean covered jar at 40°F/4°C or below and use it within four days as a conservative household limit; its shelf life has not been tested. This formulation is not suitable for shelf-stable storage or home canning. Use a clean spoon each time. Assemble the coffee over ice only when serving, and keep any added milk refrigerated. Perishable drinks should not sit out beyond two hours, or one hour above 90°F/32°C.

Questions about this recipe

Can I use apple juice instead of a fresh apple?

Apple juice needs its own syrup ratio and cooking time. It is not a direct replacement for the apple and water here. This version is designed around gently infusing fresh diced fruit.

Does the recipe need apple-flavored coffee?

No. Ordinary chilled coffee gets its apple flavor from the homemade syrup. Start with a coffee you already enjoy drinking without flavored syrups.

What can I do with the drained apple?

It will be soft and sweet. Refrigerate it promptly and use it within a day in oatmeal or yogurt if you like its flavor. It is not the same as a pie filling, and the recipe does not rely on keeping it.
