Pumpkin Pie Cake

I’ve been working on this Pumpkin Pie Cake for a couple of months.

Pumpkin Pie Cake (THM S, low carb, Gluten Free)


This Pumpkin Pie cake is pretty awesome,using an oat fiber cake as the base allows for a great texture without overloading on calories or carbs.


The first time made this cake the center fell on me… and that was with a traditional cake mix, sweetened condensed milk and bunch of eggs.

Pumpkin Pie Cake (THM S, Sugar Free)

My son George loves pumpkin pie, if given the chance he would eat it for all his meals. He asks for it instead of cake every year for his birthday.

I know the the color looks a little weird in the photos which I believe is because I used  liquid pumpkin spice extract instead of the spices,  think next time I will use the dry spices.

I did top this with a caramel sauce from here. (If you have dogs be careful as xylitol is toxic to them) This is my favorite caramel sauce, because it’s easy and stores well.

Disclosure Statement

The cake is a little messy so make sure you are plating it on a platter with a rim. I used a silicone bundt mold like this one to bake it in. (I love my silicone pans when baking with alternative flours, they make un-molding the cakes SO much easier)

I used the Trim Healthy Mama oat fiber to make this pumpkin pie cake, you can find it in the Trim Healthy Mama Store (we appreciate when you purchase through our affiliate link)


This set of silicone pans is reasonably priced and would be a great investment in your THM journey. Especially with the holidays approaching.I have struggled with this recipe only because coconut four tends to absorb huge amounts of liquid and it really gave me some headaches. This cake is moist and sweet and the pumpkin layer is rich and creamy and honestly this type of dessert is one that can win a non THM over because it tastes just like the non THM version.

    1. Psyillium husks can be substituted for Oat fiber if you don’t have Oat fiber, they really aren’t part of the recipe unless you are substituting 🙂

    1. I don’t think so, I am still in the process of correcting some of my older recipes, the calculator seems to calculate some ingredients wrong such as sugar free brown sugar as regular brown sugar… I will try to get it corrected asap.
