Preheat the oven to 180℃ Fan and line a 12-hole muffin tray with muffin or cupcake cases.
Combine the eggs, sugar, pumpkin puree, vanilla extract and olive in a stand mixer bowl and mix together until thoroughly combined.
210 g pumpkin puree, 150 g caster sugar, 2 medium free range eggs, 125 ml olive oil, ¼ tsp vanilla extract
Sift in the flour, pumpkin spice, baking powder, baking soda and Xanthan Gum.
130 g gluten-free self-raising flour blend, 2 tsp pumpkin spice mix, 1 tsp baking powder, ¼ tsp baking soda, ¼ tsp Xanthan Gum
Fold in until no pockets of flour remain.
Transfer the mixture to the cupcake cases, using an ice cream scoop to evenly divide the mixture between the cases.
Bake on the middle shelf for 20-25 minutes or until an inserted toothpick comes out clean. The cupcakes will be spongy to the touch in the centre.
Allow to cool completely before preparing the buttercream topping.
