There are plenty of places to get dessert in Key West. I know because we tried most of them! What's nice about Mattheessen's is that they offer some items that are uniquely their own. Food: The one item that really stood out was the PB Fudge Cookie. It's a large peanut butter cookie with a thick layer of peanut butter fudge, topped with another thick layer of chocolate fudge. Yes, it's one big and delicious cookie. It's expensive at $12, but it's large enough to feed a family of six. There were other items that looked equally amazing, including the chocolate-dipped coconut macaroons. On another visit a couple of days later, we tried the Key lime pie, and it was excellent. The crust had a rich, buttery flavor and held together well. Instead of the traditional meringue topping, they used whipped cream, which was a nice touch. We even asked for extra. Service: The staff were friendly, helpful, and patient. We never felt rushed. Atmosphere: [[HIGHLIGHT]]The shop is well lit, clean, and has an upbeat aesthetic.[[ENDHIGHLIGHT]] Mattheessen's is a place we would, and did, return to for a second visit. read more

Raspberry sorbet was delicious! We came after lunch and didn't get a chance to try all of the yummy looking treats but it smelt amazing. We were in and out and the ice cream was just what we needed for a quick cool down. read more

Couldn't resist popping in when our kids squealed "those cookies are as big as my face" Delicious cookies and ice cream. We asked about the Cuban coffee and hope to return soon after we were told it was incredibly strong. [[HIGHLIGHT]]Very cute shop perfect for a quick treat.[[ENDHIGHLIGHT]] read more

Dined: 5/27/26 We arrive on Key West via Celebrity Reflection cruise ship. We wanted to find the best Key Lime Pie on the island. This place is absolutely the BEST! The crust is phenomenal and the filling is perfectly balanced (not too tart). We even saw him making the pies! I also ordered their Frozen Limeade drink ($6). PERFECT drink for the humidity and temperature. The baker/server was extremely friendly and fast! If you love Key Like Pie, Mattheessen's is THE PLACE! We will be back! read more

Freshly squeezed lemonade for me in the door, but the homemade giant chocolate chip & pecan cookie with warm ice cream made us stay. [[HIGHLIGHT]]The shop is located in the middle of a busy (even on a Wednesday) street, filled with shops and visitors.[[ENDHIGHLIGHT]] We paid to park a few blocks away. The four stars is for the 5-star price. That lemonade was small for $7 and the cookie and ice cream, while tasty was $17. I'd still consider visiting again for the key lime pie. read more

I'm not so sure about their giant cookies, which appear to be their signature offering. I could be wrong (I'm allergic to chocolate, so it's probably best to ignore my cookie opinions) but they seem way too unmanageably large to possibly be good -- unless you're somewhat drunk (which you probably are, if you're in Key West... even the name of this shop has way too many superfluous letters to not be a hallucination). But, that doesn't matter. Never mind the comically large cookies. They have excellent lemonade. They have excellent FROZEN lemonade. And, because it's Key West, they have really excellent FROZEN KEY LIMEADE! It's fantastic. I got two -- or for immediately, and one for the freezer for (a little bit) later. read more

Homemade ice cream and huge delicious cookies. THE BEST! A must visit. Right across the street from La Concha hotel. read more

The best ice cream on the island. Been here a long time and owner is a great down to earth guy.

This was such a fun place with great local ice cream, the really fun part is checking out the local Keylime pie that was made just right and then dipped in chocolate. I never experienced such a thing before, but I really love it. The customer service was awesome. Highly recommended! read more

Cookies are insanely delicious! We went twice in 4 days. [[HIGHLIGHT]]Good service and a very clean establishment[[ENDHIGHLIGHT]]

This is so disappointing when you go here on vacation and you get poor rude customer service from this guy. You know what he said, cause I was standing looking at the fudge he said, 'can you move so that they can pay for their food unless you wanna pay for theirs! This was stated in such a rude and satcastic manner. . What a jerk. And that's how you represent Key West? The other guy with the dirty blonde hair was much nicer and deserves to work with customers. This other guy should just stay in the back where he belongs! read more

I have stumbled upon a Little piece of Heaven. As soon as you walk in the door, you can smell the most delicious sweet smell. There's an assortment of Homemade delicious treats they have delicious ice cream, fudge, and cookies. It was very hard to control myself. I ordered double chocolate ice cream on a waffle cone, which was delicious. I had a conversation with Jack who I thought was the owner, because he was so knowledgeable but he is the manager. Jack is absolutely so helpful and sweet. He suggested I try the chocolate covered macaroons. I took them back to my hotel and ate them the next day. These macaroons are the best thing I've ever eaten ever!!! I love them so much that I actually went back the next day to buy more and to say hello to Jack again. I wish I had more time in Key West. I would go back again. This was the most pleasant experience. I love this, place is so beautiful and They make the most delicious treats you also have to try the chocolate fudge it's amazing. Can't wait to make another trip back to Key West Too visit this hidden gem. read more

[[HIGHLIGHT]]Very small and cute.[[ENDHIGHLIGHT]] Ice cream and coffee were tasty and would love to go back for some pie!

[[HIGHLIGHT]]Stopped in for some ice cream & there weren't any other customers inside.[[ENDHIGHLIGHT]] Asked to try 2 samples & the girl behind the counter mumbled something under her breath, but eventually got samples for me. I wound up getting cookie dough ice cream & my husband got mint chocolate chip. The ice cream was just ok & was overpriced. I do not mind spending money when on vacation, but do mind when workers are rude! When we left, I said "Have a good night" & the workers never responded & seemed like they didn't want to be there. read more

Great cookies! Surprised treat of our trip! Try their specialty treats. We did not try ice cream tho.

The chocolate dipped key lime pie is a must!! My husband had ice cream and loved it! The cookies looked and smelled amazing as well! Seriously they were as big as your face! read more

My group of friends and I rode by this lovely establishment. Since I was leading the pack we all came to a sudden halt. I walked in and fell in love immediately with the LARGEST macadamia cookie. The best $$ I've spent on dessert. I don't remember the price. It was around $8 maybe. It was soft and crunchy the way cookies should always be. Each bite was just as sweet as the last. Took me three days to eat it the whole piece. Mostly because I was trying to pace myself. If your roaming around the keys and want a break from all the key lime pie. I recommend you stop by and order more than just one cookie. I only ordered one and I am filled with disappointment in my actions. What's your favorite cookie ? I bet they have it! read more

We visit the various Mattheessen's locations every time we're in town! Let me tell you -- these are probably the the absolute best cookies I've ever had anywhere, ever. Family members actually request Mattheessen's cookies as their Key West souvenirs when we come down! If you tell the employees that you'll be traveling and taking the cookies home, they wrap them up and package them for you so they won't break in transit. Their ice cream and key lime pie are fabulous, too. You're doing yourself a disservice by *not* dropping for a treat if you're in Key West. read more

Absolutely loved the cookies in this place, they were so warm and soft, taste/recipe was sooooo on point, and it was hugggggge! My favorite was the sugar cookie with sprinkles and the m&m one. Cookies are made fresh, next will I'll get some other sweets like fudge. Def get a cookie here!!! read more

Cute place for a dessert while walking around Key West. I didn't try the cookies but they looked delicious. The ice cream and cone were great. The service was meh but it was almost time to close so maybe that was it. Either way, good stop! read more

Best cookies I have ever had. I probably bought 20 peanut butter fudge cookies while I was there and have ordered no less than 24 since I've left Key West. I have a shipment in route now. read more

Absolutely delicious! I would even go in winter! The cones are homemade and worth the purchase! We tried several flavors and landed on the peanut butter cup, vanilla, cookies and cream and cake batter. Best of all, the key lime pie ice cream was smooth and refreshing! The servers were so polite and willing to let us try many flavors. The giant half pound cookies looked divine and they even had chocolate covered key lime pie on a stick. We will be back! read more

We were sitting on the second floor balcony of a restaurant across the street and I could see these giant cookies. That's how big the cookies were...I could see them from that far! Now you might be thinking, $6 is a lot for one cookie. These things are not only huge, but pretty tasty. We tried the peanut butter and a chocolate chip. My vote goes to the peanut butter one all the way. We also ended up coming back to try their key lime pie. Now mind you, this was my first key lime pie, but I really enjoyed it. That being said, I don't have anything to compare it to but I thought it was delicious. So why not a 5 star rating? At both locations I went to, the employees weren't particularly friendly. I almost felt like I was bothering them when approaching the counter. Clearly they don't care about who comes there, but a smile and helpfulness goes a long way. read more
