Gluten-Free Pumpkin Bars with Mascarpone Frosting

These gluten-free pumpkin bars are soft, moist, and warmly spiced, with a rich mascarpone frosting that makes them perfect for fall gatherings and holiday tables. Naturally sweetened with just a few Medjool dates — without sugar, syrups, or excessive amounts of alternative sweeteners — they have all the pleasure of a festive pumpkin cake in a more balanced, nourishing form. Almond and tigernut flours, pumpkin, and extra virgin olive oil give them flavor, substance, and a beautifully tender texture.

A different kind of gluten-free pumpkin bar

Many pumpkin bars are essentially conventional sheet cake made with a gluten-free flour blend and plenty of added sugar. This recipe takes a different approach.

Tigernut and almond flours give the bars more flavor and nutritional value, while a small amount of tapioca helps create a soft and light texture. Pumpkin keeps the crumb moist, and extra virgin olive oil adds richness without weighing it down. Instead of relying on refined sugar, the batter is sweetened with three Medjool dates, complemented by the natural sweetness of pumpkin and tigernut flour.

The mascarpone frosting turns the simple pumpkin cake into a festive dessert. It is rich, creamy, and only lightly sweetened, allowing the pumpkin and warming spices to remain at the center of the recipe.

Ingredients you will need

The dry mixture is made with tigernut flour, almond flour, and a small amount of tapioca flour. This combination is important to the character of the recipe: tigernut flour contributes subtle sweetness, almond flour creates a tender crumb, and tapioca provides enough starch to keep the bars light and fluffy. Baking powder and baking soda help the batter rise.

I would not recommend replacing this flour combination with a general-purpose gluten-free blend. Gluten-free flours behave very differently from one another, and a direct substitution would change both the moisture balance and texture.

If you are new to baking with tigernut flour, you can learn more about how it behaves in my guide to tigernut flour.

For the wet mixture, pumpkin puree is blended with eggs, extra virgin olive oil, Medjool dates, inulin, vanilla, and pumpkin pie spice. Blending these ingredients creates a smooth mixture and ensures that the dates are fully incorporated into the batter.

Be sure to use plain pumpkin puree, not sweetened or spiced pumpkin pie filling. You can use canned pumpkin or well-drained homemade puree, provided it has a similar thick consistency. I always prefer a home-baked pumpkin. It has more sweetness and flavor, and a less watery consistency, which contributes to a better result overall.

I use inulin in a lot of my baking, not so much for added sweetness, as for its contribution to a better crumb. However, if you don’t have it, feel free to use allulose, which is one of my favorite natural sweeteners.

For the spice, use two teaspoons of pumpkin pie spice or combine one teaspoon of pumpkin pie spice with one teaspoon of my Warming Spice Blend for a more complex flavor.

The frosting is a simple combination of cold mascarpone, crème fraîche or sour cream, and a small amount of your preferred sweetener. Mascarpone is naturally rich and mild, while the cultured cream adds a pleasant tang and softens it into a spreadable frosting.

How to make gluten-free pumpkin bars

Begin by lining an 8 x 8-inch (20 x 20 cm) metal baking pan with parchment paper. A metal pan is preferable because it conducts heat efficiently and helps the center bake evenly.

Whisk the flours, leavening agents, and salt together in a large bowl. In a high-powered blender, combine the pumpkin puree, olive oil, eggs, dates, spices, inulin, and vanilla, blending until completely smooth and creamy.

Pour the pumpkin mixture over the dry ingredients and gently fold everything together with a spatula. Mix only until no dry flour remains; overmixing can make the finished bars heavier. Transfer the light, fluffy batter to the prepared pan and smooth the surface.

Bake until the center is set and a toothpick comes out clean. Let the cake rest briefly in the pan before transferring it to a cooling rack. It must cool completely before frosting, or the mascarpone mixture will soften and slide.

While the cake cools, whip the cold mascarpone, crème fraîche, and sweetener just until smooth and creamy, then refrigerate the frosting until needed. Once the cake is completely cool, spread the frosting over the top and finish with cinnamon, pumpkin pie spice, or edible flower petals.

Cut into squares and serve chilled or allow the bars to sit briefly at room temperature before serving for a softer texture.

Storage

Because the frosting contains mascarpone and crème fraîche, store the pumpkin bars in a covered container in the refrigerator for up to three days.
