When I have left over coffee that I did not have time to finish, I put it in ice cube trays and freeze, then I put in a ziplock bag. If I feel like having iced coffee or mocha, I put it in the blender. Pour into a glass and enjoy!

Here's a couple of tips to make use of leftover coffee.
Instead of reusing coffee grounds as some people do, I reuse the leftover coffee itself. It seems that nobody wants to drink the last cup or two in the pot in our house so, instead of throwing it down the sink, I blend it with the fresh pot. I decrease the fresh grounds for the new pot I'm making by a scoop or two and mix the fresh water with the leftover coffee from the previous pot. I've been doing this for years; it hasn't damaged the coffeemaker and I still get compliments for making a good cup of coffee.
Leftover coffee can also be used when making iced coffee or a smoothie. Freeze leftover coffee in ice cube trays and use coffee cubes instead of plain ice.
Coffee cubes added to gravy or stew gives a lovely color and taste.
Believe it or not, coffee makes an awesome after shower hair rinse for dark haired people and it smells great.

I have been wondering what to do about my leftover coffee. Then it hit me. Coffee ice cubes. Once they freeze, I transfer them to a plastic bag to be used later. I hate waste.
When I have leftover coffee in the pot, I put it into an ice cube tray then freeze it. When frozen, I put the cubes into plastic Ziploc bag then return it to the freezer. The next time that I want to drink my coffee quicker without waiting for it to cool, I just put 2-3 coffee cubes in the cup (depends on the size cup you are using). Then I can drink it without worrying about diluting the brew.

I used to freeze the leftover coffee in an ice cube tray for iced coffee, which I still do. I developed a fondness for Thai coffee so I decided to make my own version of it and everyone seems to like it.
For those who can't tolerate regular coffee I made an extra strong pot of decaf, let it cool, pour into a pitcher with one can of condensed milk and the frozen coffee ice cubes. If necessary you can add some extra fat free 1/2 and 1/2. It's very refreshing and with the high price of coffee this is a great way not to waste it.
Source: This was inspired by many trips to the Thai restaurant where they charge $4.00 per glass, so I thought there must be a way to enjoy this at home especially since we never drank the leftover coffee. Now we do and it's a great taste and no waste!

I have a cup of coffee for breakfast and a dish of oatmeal. Since I love the taste of coffee (and to save a few calories by not using milk on my oatmeal), I just add coffee to the bowl after I take it out of the microwave. Add a little honey instead of sugar, if you want it a little sweet. Coffee thins it down and it has a nice flavor with the oatmeal.

When you have leftover coffee, add some water and use it to water your plants (houseplants or garden). It acts like plant food. Coffee grounds can be mixed in your garden soil for a boost.
I planted my acid loving herbs near my kitchen door, and in the morning when my morning coffee finishes brewing, I put the used grounds directly onto the soil, instead of having to walk them to the compost bin or throw them away! Easy peasy and smelling my fresh, homegrown basil first thing in the morning is now part of my wake-up routine!

I freeze left-over coffee in an ice tray to use for iced coffee. when you make fresh coffee to pour over the coffee isn't diluted. It makes coffee beverages easier in your blender as well. Add the flavored coffee creamers and sweetener to make your own inexpensive coffee beverages. No more $8 coffees at the local coffee shops.

After making my coffee in the morning, I always put my leftover coffee in a thermos because my coffee maker automatically shuts off after a certain amount of time and it gets cold. I cook for one so I don't want to waste it by throwing it out. This method is good for any hot liquid, tea, hot chocolate, etc. if you want to make it at a convenient time and have it ready for when you need it.
This is also great for camping when you only cook once or twice a day. You can also put leftover soup, etc. in a wide mouth thermos.

You know how coffee doesn't taste so good after you've had it hot, and it's been on too long? Use the left over coffee from the morning to make a hot chocolate. It tastes better then using plain water and uses up the left over coffee.

Here are questions related to Uses for Leftover Coffee.
I have read about using coffee grounds and eggshells for plants, but can I use cooled coffee? I heard someone mention it at a greenhouse, but I don't know how much to use. I usually make 1 TB for 1 cup. Any recommendations? This would be for my vegetable garden and a few outside plants.

I take what ever left over coffee and finish filling the pot with water and add directly to plants inside or out. The really thrive on it.

Don't let your morning coffee or evening tea go to waste! Try making ice cubes with either brew. Get creative by adding some clean fresh rose petals or spirals of lemon or bits of mint. Try shaved chocolate curls in the coffee cubes or even some mini chocolate chips!

I used to put coffee grounds around the blueberry bushes; wonder if watering them with coffee would also be helpful. (08/30/2004)

I use my left over coffee in my coffee cakes, and frosting for the coffee cake. I also put the coffee grounds around my rose bushes. (09/02/2004)
I've added it to chili - tends to deepen the flavor. It's cool back here in the office where I keep the coffee pot so if there's some left I reheat it the next morning - just make sure to turn the heat off or it will make it scorch (10/06/2004)

Mix 2 cups flour and 2 cups sugar in a bowl. In the microwave heat to boiling: 1 cup margarine/butter, 1 cup strong brewed coffee and 1/4 cup cocoa. Pour into bowl with flour and sugar. Add 1/2 cup sour milk (milk with a little vinegar in it is what I do), 2 eggs, 1 tsp. baking soda and 1 tsp. vanilla. Mix well at high speed. Pour onto large greased cookie sheet (I use a jelly pan). Bake at 400 degrees F for 20 minutes. Make your frosting while the brownies are in the oven: Heat till boiling in microwave the following: 1/2 cup margarine, 2 Tbsp. cocoa and 1/4 cup milk. Stir well to mix, then mix in 3 1/2 cups icing sugar and 1 tsp. vanilla. Cool slightly and then spread over the hot brownies, cool and cut. Super delicious! (05/18/2005)
