gluten free pumpkin sheet cake recipe

It’s that time of the year.

One of my favorite times of the year when the leaves are changing color, the farmers markets are a bounty of local fruits and vegetables and the smell of pumpkin starts to fill our kitchens.

It is thanksgiving soon here in Canada and that means gluten free pumpkin pie, pumpkin spice syrup, pumpkin desserts as well as roasted pumpkin as a side veggie.

Basically it is pumpkin season!

I have been busy in the kitchen developing new gluten free pumpkin recipes and have 3 new ones that I will be sharing this week.

First up will be a gluten free pumpkin sheet cake. This recipe is super easy and you have a few options with the cake.

Leave it the way it is.

Icing the whole thing or as I did slice each piece in half, sandwich the halves with whipped cream and then top with a homemade brown sugar icing.
