A moist pumpkin cake topped with a deliciously creamy buttercream, these Pumpkin Squares with Cinnamon Vanilla Buttercream Frosting are a fall favorite!
I first made these Pumpkin Squares last fall when my sister Maureen sent me the recipe and said, “you absolutely have to try these!” She said they were my niece Ally’s favorite. Well, all I can say is that Ally’s got great taste, and now they’re one of my favorites. The cake is incredibly soft and moist, with the wonderful flavors of pumpkin and cinnamon. As soon as I feel fall is in the air, I whip out my half sheet cake pan, and plan a little dinner party just so I can make them, and not eat them all myself!!
I’ve made them several times with cream cheese frosting, but this time I decided to change it up a bit, and I made my homemade Cinnamon Vanilla Buttercream Frosting. I’m a huge cinnamon fan, especially during the fall season. Cinnamon and fall just seem to go hand in hand for me, and it’s just the perfect complement for these pumpkin squares. I love the little flecks of cinnamon in the icing.
I also decided to step up my game in the icing department and try my hand at icing roses. I have seen so many gorgeous cakes with icing roses on Pinterest and other awesome blogs that I just had to give it a go. I’ll be honest, I’m not very talented in the cake decorating department, but with some encouragement from my good friend Hakeem, the pastry chef, and a little help from an online tutorial, I did it! They may not look perfect, but since the cake is, (thanks Ally!) all my guests loved it!
As Natasha says in the online tutorial, use a Wilton 2D tip to pipe the roses and practice first on a baking sheet until you get the hang of it. I thinly iced the sheet cake first, then cut them into squares, and finally piped the roses on top of each square.
Take it from my niece Ally, you don’t want to miss out on making this simple and incredibly delicious fall dessert. It’s sure to impress!

These little squares of pumpkin, cinnamon and buttercream lovin’ look divine, Mary Ann! And, your icing roses look preeeetty dang perfect, if you ask me! I am going to have to take your advice and make these for my next dinner party, because I am pretty sure I can’t be trusted with an entire pan of these all to myself! Pinned! Cheers, lovely!
I know right?! Who can resist pumpkin treats this time of year Cheyanne! Enjoy!
Your rosette is perfect Mary Ann! Good job! It’s harder than it looks, right? It’s early, but my mouth is watering already for these delicious pumpkin squares. They are perfectly baked, iced and cut! Your guests were luck to be able to sink their teeth into these beauties! I’m with you on the cinnamon… I buy in bulk so I can stock up and get a good price. It can get expensive. I love it when family and friends are looking out for our culinary prowess. Your pastry friend and sister are super sweet to help out in the effort. Delicious my dear! Have a great week!
Thanks so much Traci! I know, my friend Hakeem is always a great help! He is so talented, and always gives me confidence when baking in the kitchen! You have an awesome week too!

Thanks Rose! They will be a hit! The roses took some practice, but they weren’t as hard as I thought!
These look AMAZING!!!! Do you think swerve can be used as the sugar in this recipe?
Hi Kari. Thanks so much! I have never used Swerve, but I got on to their site and they say you can use Swerve just like you use sugar. So the cake calls for 1 2/3 cup granulated sugar, so you just use 1 2/3 cup Swerve! Enjoy!
OK these are too pretty to eat. Wait I lied..I will down two in a second.
Thanks Zainab! Ha! I ate more than two!
Oh wow these are so so so so gorgeous! I want pinning this fast and in a hurry!
