• Easy: No brewing and no coffee machine needed.
• Creamy: Flavored creamer makes every glass smooth and rich.
• Ready to grab: A cold glass is always waiting in your fridge.

Before You Start: The Basics

• Use a clean 1-gallon jug with a tight cap. Rinse it with hot water first.
• Instant coffee dissolves best in hot water, so do not use cold water for the first step.
• Pick a flavored creamer you love. Vanilla, caramel, and hazelnut all work well.
• A funnel keeps the pouring neat and saves coffee.

Ingredients for Homemade Iced Coffee Gallon

• 1/2 cup instant coffee granules
• 1 cup white sugar (add up to 1 1/2 cups for extra sweet)
• 2 cups hot water
• 3/4 cup flavored creamer
• About 12 cups cold milk (enough to fill the jug)
• Ice, for serving

How to Make Homemade Iced Coffee Gallon (Step by Step)

Step 1: Add the coffee and sugar

Place a funnel in a clean 1-gallon jug. Add the instant coffee and the sugar.

Step 3: Stir until dissolved

Stir with a long spoon until the coffee and sugar are fully dissolved. You should see no grains at the bottom.

Step 4: Stir in the flavored creamer

Pour in the creamer and stir again. The coffee will turn a lovely creamy brown.

Step 5: Fill the jug with milk

Add cold milk until the jug is almost full. Leave a little room at the top so you can shake it.

Step 6: Shake and chill

Put the cap on tight and shake well. Chill in the fridge for at least 2 hours.

Step 7: Pour over ice and enjoy

Shake the jug once more, then pour over a glass full of ice. Add a straw and sip.

Tips for the Best Batch

• Shake the jug before every pour. The coffee can settle at the bottom.
• Use whole milk for a creamier drink, or low-fat milk for a lighter one.
• Freeze some of the coffee in an ice cube tray. Your drink will not get watery.
• Use a strong instant coffee for a bolder taste.

Variations

• Vanilla: Use vanilla creamer and add 1 teaspoon vanilla extract.
• Caramel: Use caramel creamer and drizzle caramel inside the glass.
• Mocha: Stir in 1/4 cup chocolate syrup with the creamer.
• Less sweet: Cut the sugar to 1/2 cup and use an unsweetened creamer.
• Dairy-free: Use oat or almond milk and a plant-based creamer.

Storage

Keep the jug tightly capped in the fridge. It stays fresh for 7 to 10 days. Always give it a good shake before serving.

FAQ

Can I use ground coffee instead of instant coffee?

This recipe works best with instant coffee because it dissolves in seconds. For ground coffee, brew a strong batch first and use that in place of the hot water and coffee.

How long does homemade iced coffee last?

It lasts 7 to 10 days in the fridge when the jug is tightly closed.

Can I make it less sweet?

Yes. Start with 1/2 cup sugar, taste, and add more if you need it.

Do I need flavored creamer?

No, but it adds creaminess and flavor. You can use plain creamer or a splash of vanilla extract instead.

Can I make a smaller batch?

Yes. Cut every ingredient in half and use a half-gallon jug.
