Homemade Coffee Marshmallows

I love a good marshmallow.  There is a gourmet market near my house that sells four marshmallows for TEN DOLLARS.  That is INSANE.  Marshmallows are very simple to make and once you’ve had a homemade one you’ll never want to eat them from the bag again.  Also, people seem to think it’s really difficult so you’ll come off as a crafty superstar. 

I made these coffee flavored as a little V-Day gift for Scarlet’s coffee-loving Papa, but you can make yours vanilla, or peppermint, or whatever flavor you like.

3 packages of unflavored gelatin
1 cup ice water, divided into 1/2 cups
1.5 cups granulated sugar
1 cup light corn syrup
1/4 tea salt (coarse or sea salt)
1 tablespoon coffee extract (or 1 teaspoon vanilla)
you can add food coloring if you want
1/2 cup powdered sugar
1/2 cup cornstarch

1.  In the bowl of your mixer with the whisk attachment, empty the 3 packets of gelatin and add 1/2 cup ice water.  Let it sit to “bloom” while you do the other stuff

2.  In a sauce pan mix the 1.5 cups sugar, the other 1/2 cup ice water, 1 cup corn syrup and 1/4 teaspoon coarse salt.  Put the lid on and bring it to a boil.

3. Remove the lid and let it cook until it reaches 240 degrees.  Temperature is important with this.  I used a meat thermometer because I couldn’t find my candy thermometer.  It worked out fine it was just a pain to clean.

Meanwhile your gelatin has been “blooming” and will look like this:

4.  When it hits 240 degrees immediately remove it and pour it into the mixer on top of the gelatin.  Start the mixer at a slow speed so you don’t splash 240 degree sugar syrup on your face:

Put the lid on the mixer and turn it up to way-high speed:

5. That is going to be whisking for a while, so prepare your pan.  use a brownie pan and cover it in plastic wrap.  Coat the plastic wrap with a bunch of non-stick cooking spray.  In a bowl mix 1/2 cup powdered sugar and 1/2 cup cornstarch and generously sprinkle it around.  Pick the pan up and shake it to coat the top and sides.  Pour the excess out and then back in, make sure it is coated really well because your marshmallows will be sticky, and if there’s too much you can always brush it off later when the marshmallows are done:

6. Ok, back to your mixer.  The whole mixing process will take about 8-12 minutes.  Your marshmallows mixture is going to about double or triple in size.  it will start like this:

and get as big as this:

You will know it is done when it stops growing.  At that point add your 1 tablespoon of coffee extract or your teaspoon of vanilla or whatever flavoring you want to use and mix one more minute.

7.  It will be thick and sticky:

Pour it in your prepared pan:

Smooth out the top:

And coat with a bunch more of the powdered sugar/cornstarch mixture:

And put plastic wrap over it:

Let it sit overnight (or at least 4-6 hours).  Reserve the remaining sugar/cornstarch mixture.

8.  In the morning take the plastic wrap off:

And remove the marshmallows to a cutting board:

Dust off the excess sugar/cornstarch mixture into a bowl. Cut the marshmallows in half, then quarters, then the other direction:

Dip each one in the sugar/cornstarch mixture until it isn’t sticky:

Resist urge to immediately eat all of them:

Serve yourself a few:

Package remainder in cute boxes.  These are martha stewart brownie boxes from Michaels:




I made a batch today myself using Martha's recipe. I like yours better:) the pictures are great. I am cutting mine in the shape of houses for our housewarming party this weekend, can't wait to taste them- YUM!


Is there a way to do this without the mixer? I have a hand mixer with a whisk attachment but how does this effect it? Any ideas?


jessica you could totally do this with the whisk attachment on a hand mixer, you'd might just get a tired arm. it would probably be a good workout. maybe i will do that next time.


I am going to make these for a wedding shower I'm hosting. Thanks for the wonderful pictures, step-by-step tutorial and the positive affirmation that anyone can make these!


I have made homemade marshmallows before (I have made peppermint, vanilla bean and saffron) but using coffee seems like an awesome idea. I think I am going to have to try coffee now, since I cannot get the idea out of my head. What do you think if I used a mixture of powdered sugar and sifted cocoa powder – would that make them moka marshmallows?


there is a product called Agar made from seaweed but i've never tried it. it's used in lots of japanese candies.


I just got these made yesterday for an early christmas present for my sister. I couldn't find coffee extract so I just brewed a strong 1/2 cup of coffee & used that in place of the 1/2 cup of water when cooking the sugar etc. I'm not a coffee person but they do have a coffee flavor so I'm sure my sis will love them.


Im gonna make these for xmas presents, Cut with small star and snowflake cookie cutters,I'll pack them in a celophane bag and put in a basket with a jar of homemade coco mix! Thanks for the awesome idea!


Do you think instead of powdered sugar you could substitute nesquik for chocomallows?

These look much better than Martha's. I think I shall try these soon. πŸ™‚


So I made these last night for a party tonight….but mine did not get as big as the pictures πŸ™ I bought 3 boxes of gelatine (I have never used before) when I got it home it had 4 envelopes, so I only put 3 in….was I suppose to put all 3 boxes in? Any help would be great, Thanks

Hi Amy! you were right, just 3 packets. The marshmallows don't rise after you're done mixing them, so they either needed to mix longer or you used a bigger pan than me. I used an 8" square brownie pan. Hope that helps. I bet they are still delicious! πŸ™‚

I would like toi talk about candy thermometers and why some of you are afraid to use one. I have lots of experience with them, if anyone needs advice.

I am a 58 year old mom, and grandmother of (nearly) six grands! I am SO PROUD of every young woman who participates on this site! It is not easy to take care of children, much less cook and sew and do projects with them. Just wanted to offer my encouragement to any mom who needs advice or encouragement from a mom with many years' experience. I just LOVED the sewing contest and the entries!!! Very impressive, both in creativity and workmanship!

Debbie Thornton

Amazing! What an easy recipe. I used a pack of Starbucks VIA for the coffee. I mixed it with 1/2 cup of water and used it with the sugar, corn syrup mixuture.

I am opeining a wine bar and currently working on the menu. I have been considering offering S’Mores – how cool would it be to make home made marshmallows for those S’Mores?!?!?! Of course, I would have to prepare them ahead of time and when they’re gone…….


Thank you for this well written and amusing recipe. I’ve been thinking about making marshmallows for a few months, looks like now’s the time!


I am going to make these for a housewarming party! Thank you for the great recipe and pictures.
