2. Make Ice Cream
What you’ll need:
- 1 cup of leftover coffee
- 1 to 1 ½ cups of whole milk
- ½ cup of heavy cream
- 2/3 cup of sugar
- 4 egg yolks
- a little bit of salt

- Beat egg yolks in a bowl, then add salt and sugar and whip until the mix is foamy
- Pour the milk and heavy cream into the mixing bowl and continue whipping so everything is well combined
- Take the content back into the pot and cook it at low to medium temperature for no longer than 15 minutes
- Take the pot off the heat and add leftover coffee
- Let it sit for 10 to 20 minutes at room temperature, then freeze
3. Make Ice Cubes
Pour coffee leftovers into ice cube trays and leave them to sit in the fridge for as much as you want.
You can use them when making iced coffee (as hot coffee would dilute them).
But you can also make cocktails with them to add some more flavor to your fav drinks.
Alternatively, you can simply add several cubes when enjoying a cup of cold milk.
4. Make a Frappé Coffee
What you’ll need:
- Whipped cream
- 2 cups of milk, ideally almond milk
- 3 ½ tablespoons of granulated sugar
- 3 to 4 tablespoons of chocolate syrup
- coffee ice cubes
- shaved chocolate bar
How to make frappe?
- Blend milk, sugar, chocolate syrup, and coffee ice cubes in a blender
- Pour the mixture into your fav cup
- Top with shaved chocolate and – enjoy.
5. Add Some Coffee to Chili
If you’re feeling braver and more adventurous, then you can try adding leftover java to chili.
Add ½ or ¾ cup of coffee when preparing a homemade chili dip.
By doing so you will achieve a richer and deeper flavor and color!
6. Use it When Roasting Meat
The acidity in the coffee can help you tenderize the meat when roasting/baking it.
You can add one to two tablespoons and your meat will get a little extra flavor.
It might sound weird and even off-putting but some coffee on your steak when preparing it for dinner can help to make it nice and tender.
7. Make a Smoothie
Blend several coffee ice cubes with vanilla, chocolate.
Or whatever protein powder you like, even non-dairy milk and frozen fruits.

This will help you make the tastiest, healthiest smoothie you’ve ever tried.
8. Make Sauces
You can use your unused java to make tasty sauces, like the ones that we list below.
- Whisk ½ cup of leftover coffee with several egg yolks
- Stir in butter and add salt, pepper, and paprika
- Mix ½ cup of coffee with chili powder, brown sugar, ketchup, 1 cup of onion, 1 cup of cloves, cumin, dark molasses and mustard
9. Make Coffee Liqueur
Here’s how to do it:
- Mix brown sugar with leftover coffee
- Add rum or bourbon and spices (vanilla, cinnamon)
- Pour it into a glass bottle
- Let it sit in the refrigerator for a few days
You can use this liqueur as ice cream topping or you can even add it to cocktails.
10. Fertilize Your Garden
Dilute leftover coffee with water in a 1:3 or 1:4 ratio and pour over your garden plants.
This trick applies to black coffee only i.e. no sugar, creamers, or milk.
Coffee can provide multiple nutrients for plants, including calcium and magnesium, nitrogen, and strengthen the stems and boost their growth.
Repeat every two weeks for best results.
Orchid, iris, gardenia, magnolia, begonia, and azalea like coffee the most.
Yet, if the leaves start turning brown or yellow, that means the soil in your garden is already acidic.
This is a sure tale sign that you should stop this practice.
11. Hair Dye
Mix 2 to 4 cups of leftover coffee with your fav conditioner and apply the mixture after shampooing.
This will give your hair a nice, deep brown shade and stimulate hair growth.
We wouldn’t recommend using it on lighter, blonde hair shades tough!
What to Do With Used Coffee Grounds?
Once you’ve used the liquid and don’t know what to do with the grounds, here are some quick tips!
1. Get Rid of Odors in the Refridgerator
Collect the grounds in a small jar and leave it open.
Put the jar in the fridge and the grounds will soak up those nasty odors in your fridge.
2. Use Them as a Shower Bath Scrub
Use a bath sponge and dip it in a jar filled with coffee grounds.

Rub your skin with the sponge and the coarse texture of the grounds will remove layers of dead skin.
You can also mix coffee grounds with honey, coconut oil, coarse salt, brown sugar, and your fav essential oil/vanilla extract to make an exfoliating wash.
3. Scour Away Tough Dirt
Use a sponge and some coffee grounds to clean your pots and pans.
Although they are abrasive, they still not too abrasive so you can still use them to scour away stains and bits.
4. Grow Mushrooms
Use coffee grounds as a substitute for sawdust when growing mushrooms.
You won’t need to sterilize them and you’ll have some available every day.
Use fresh, espresso grounds for best results (within 24 hours after brewing).
- Contains 1 - 12 ounce bag of ground coffee
- Original Blend is the coffee that made Dunkin'...
- Medium roast coffee, specially blended and roasted...

Did somebody say coffee? Two shots of espresso for me, thanks. Oh, nevermind – I’m Simon, nice to e-meet you, dear CoffeeLifior! I like to write, drink coffee and I believe in Jesus. Highly-caffeinated drinks are my thing, but you can occasionally see me sip on decaf (my wife never finishes her coffee). Speaking of which, I’m off to grab another cup of caffeinated goodness now, laters!
