Heat the cider over medium-high heat in a saucepan and reduce it to 120ml (US ½ cup). This should take around 12 to 15 minutes. When reduced, set the cider aside and let it cool down.
350 ml dry apple cider
In the meantime, make the chia eggs: Mix the ground chia seeds in 6 tablespoons of water. Set aside for 10 minutes.
2 Tbsp ground chia seeds, 6 Tbsp water
Preheat the oven to 200°C/400°F/Gas 6. Place 12 large paper baking cases in a muffin tin.
In a mixing bowl, stir together the self-raising flour, sugars, baking powder, baking soda, salt, 2 teaspoons of cinnamon, ½ teaspoon of nutmeg, and ¼ teaspoon of cardamom.
250 g self-raising flour, 75 g caster sugar, 75 g dark brown sugar, 1 tsp baking powder, 1/4 tsp baking soda, 1/2 tsp salt, 2 teaspoons ground cinnamon, ½ teaspoon ground nutmeg, ¼ teaspoon ground cardamom
In a separate bowl, whisk together the oil, milk, reduced cider, vanilla extract and chia eggs until fully combined.
75 ml vegetable oil, 100 ml non-dairy milk, 1 teaspoon vanilla extract
Mix the apple cider mixture into the flour mixture until well combined. Do not overmix.
Share the batter evenly between the muffin cases.
Place in the oven for around 20-25mins. Insert a skewer to check they are cooked. The skewer or toothpick should come out clean.
When done, leave the muffins to cool in the muffin tin for 5 minutes.
In the meantime, prepare the toppings: In a shallow dish, mix the granulated sugar, 1 teaspoon of cinnamon, ½ teaspoon of nutmeg, and ¼ teaspoon of cardamom. Place the melted butter into another shallow dish. Dip the top of the first muffin in the butter, and then roll in the sugar mixture until the top is coated all over. Repeat with the remaining muffins. Sprinkle some of the remaining sugar mixture on top of each muffin. Leave the muffins to cool on a wire rack.
