If there were a way to bring these goodies home to Texas I'd be in big trouble. Amazing, and a must have while in KW!!! read more

Treats taste as good as how the outside aroma smells. Went in to try the key lime pie and did not leave disappointed. The individual slices are already packaged. We sat outside and shared a slice on the bench outside. The key like pie is perfectly creamy with the perfect amount of sweetness and lime flavor. The pie crust was probably my favorite part. Would definitely recommend! read more

Great desssert' and key lime pie! Definitely recommend it. Great service and lots to choose from.

A nice ice cream and sweets store. We had ice cream but were tempted by the large (really large) cookies that had a wonderful aroma. The ice cream was great and the cones were large. A nice place to get a cool sweet treat on a hot day in Key West. read more

Mattheessen's - Started eatting it before I took the picture but you get the idea! - Desserts Near Me - Key West, Florida

Got a key lime pie. Crust was good but wish I went to blue heaven instead because theirs was just like any other key lime pie you can get.

Cookies are humongous and yummy. The edges are too crispy for my liking but the inside was yummy! Must visit

My hubby was craving ice cream after dinner and I found this place. It was actually across the street from where our hotel, conveniently located on Duval street. The staff was welcoming and nice and offered fudge samples. I am not a big fan of fudge in general so I cannot comment on that. We tried samples of Cuban coffee, turtle (the one with caramel), cookies and cream, and toasted coconut. We needed by Cuban coffee and cookie and cream on a waffle cone. Both are very tasty and usually I won't go for cookie and cream but theirs is really good with real big cookie crumbs. My hubby said it was the best cookie and cream ice cream he had. The cookies are huge as everyone else mentioned and the oat and raisin one looked really good. But I got to watch my waistline :) maybe next time. It is definitely a paradise for dessert with their Cookie Monster, banana split menu offering. They also offer packaging and shipping if you are interested. read more

I would of given 5 stars because their cookies are really good, however the last couple of times I have gone it's been very difficult to get my favorite cookie the peanut butter with fudge on top. The last time I was here I drove from my house in Summerland Key to Key West just for that cookie and made multiple trips in a week and it was very disappointing. read more

You can't go wrong with a chocolate chip cookie! So soft and delicious. The peanut butter with fudge topping is the best of both worlds as well. read more

The peanut butter cookie with chocolate frosting was DELICIOUS!! We came from Rhode Island for vacation and had to take some home when we left. We definitely recommend! read more

Probably the best Key Lime pie I've had in all my travels around the country that includes nearly 40 visits to Diners Drive Ins and Dives joints. Ice cream was fresh and home made in small batch. Half pound cookies and the special recipe that was crafted by a Key West Native. Worth the stop. read more

Cute little ice cream shop. I tasted the cake batter ice cream which was delicious but at the suggestion of the server, I tried the toasted coconut and damn it was delicious! Creamy with perfectly toasted coconut. Will return on my next trip and try the cookies! read more

We are ice cream aficionados and are not easy to please. Mattheessen's is the best ice cream in Key west, period. If you want something a little lighter, definitely go for the key lime sorbet. Total bliss in every spoonful. Finally, I've tried multiple key lime pies here in Key West and Mattheessen's is the best. 5 stars all the way! read more

OUTSTANDING COOKIES!!!! the place was very cold when we came in which was great because it was a gruesomely hot day. next time i'm heading to key west, this is the FIRST PLACE that i am going. forget the hotel! read more

I'm sure most people expect the quality to drop when they see GIANT cookies, but these are some of the best cookies I've ever tried. The M & M sugar cookie is probably my favorite due to how soft and flavorful each bite is. You're missing out if you don't order some! read more

Wow talk about some good ice cream and some large portions! Softball size scoops! I had the Cuban coffee and almond toffee, both were amazing! I highly recommend the Cuban coffee, not really tasting the Cuba but the coffee is all there. Rich creamy and caffeinated. read more

Ugh Yelp is such a hit or miss with the reviews. I wish people actually left reviews based on how good the food tastes not based on niceties. Yes the owners were super welcoming and accommodating but the food here was just ick. I would not come back. They gave big pieces of fudge samples but they were way too sweet. I came for the ice cream and wasn't impressed with any of the flavors. Everything was too sweet to the point where the sugar overpowered the flavor. I love pistachio flavored ice cream but the one here was dyed a weird green color, not even light green, but a leprechaun green. Ew. I expect so much more from homemade ice cream. Bought a giant chocolate chip cookie and tastes like a straight up sugar, not so much chocolate. Even the chocolate chips used had more sugar than cocoa. Maybe I'm spoiled because I had the best chocolate chunk cookie from the Paris pavilion in Epcot a few days ago. This one looked good but cannot compare. The key lime pie taste like the artificial stuff you can buy from grocery stores. I just came from Miami and ate at Joe's Stone Crab and their key like pie was 10x better, actually taste like a lime cheese cake, where as the one here taste like a sour pudding with artificial lime flavor. It's like night and day difference between a margarita made from fresh squeezed limes and margarita mix. The baked goods here taste like the mediocre ones you can find in a grocery store just bigger portions. Everything was expensive, too! 3 ice cream cones, a cookie, 1 slice of pie cost me $30. read more

Delicious. Cookies? Delicious. Ice cream? Delicious. Location? Perfect. The people? Amazing. I was surprised at how fun, homey and wonderful this treat shop was. For what you get as well, prices are very reasonable. read more

Get the chocolate chip with macadamia nuts cookie. I have nothing else to say. That is all.

Great guys. We stop in ever visit to Key West for our annual ice cream treats and always end up talking to the guys behind the counter for 10 minutes. She gets the frozen key lime pie on a stick. She says the chocolate coating is delicious but kinda too thick and brittle. Tougher to manage than the normal thinner coat, and it can kinda overpower the main event.... the key lime pie. It does have a nice thick layer of pie crust in there though. I get a waffle cone with mint chip and chocolate. Its super tasty, the cone is great, but i just wish it was bigger. I guess the places back north just pile it high.... cookies look amazing and are bigger than your head but we've never had one. read more

What Bill said is right! This place is the devils house of sweets! WIth ice cream and cookies the size of children can consume.

Now just called Mattheessen's, comfort food doesn't get much better than this. Huge 6" cookies that are soft and tender, crammed full of nuts, chocolate chips, or whatever toppings you request. All natural and made with real butter, there is nothing like them. Ice cream is also top notch. I enjoyed a key lime shake that was just sweet enough to offset the lime but not so sweet as to be cloying. (Think sweet cream versus vanilla). There was a huge assortment of fudge as well, but sugar overload was on the horizon so I decided to pass on that. Cookie flavors are peanut butter, oatmeal raisin, chocolate chip, sugar, an chocolate chop with walnuts, macadamia nuts, pecans, or a mix of all three. Don't leave the Keys without stopping here. read more

The customer service was great and the ice cream even better. The toasted coconut ice cream was my fave, the pistachio and Cookie Monster were good contenders as well. As I was checking out, the toasted coconut macaroons were calling my name and I bought one of those as well. Those were fantastic as well. read more

Had the Colombian coffee and Key Lime ice cream. So rich and smooth. Great flavors! My husband had peanut butter and Kahlùa. Said they were great too! The cookies. OMG! Huge. Soft. Sooo good! They are the first things you see when you walking the shop. Made the shop smell delicious! read more

I was super excited to try the Cookie Monster, but the man that helped me made me feel as I was inconveniencing him and did not even listen to my request. I ordered a monster cookie with only one scoop of ice cream and that's literally all he gave me. The cookie was not warm and when I asked for the fudge and whip cream he said he would have to charge extra. 1 piece of fudge and 1 cookie was $18 and the cookie went in the trash. Only giving 2 stars because my daughters fudge didn't completely suck. read more

Giving this a 4 star experience because of the rude service we received. We stayed because we wanted to try to ice cream which the toasted coconut was amazing. The giant cookies looked and smelled delicious but we did not purchase one. Great variety of flavors that can be made into a shake too! A little bit of every type of sweets to satisfy your craving. read more
