Heat the oven to 185C/130C fan/gas 2. Butter a 20cm springform cake tin that’s about 7cm deep, then double-line with baking parchment. Beat the butter and sugar using an electric whisk until light and fluffy. Mix in the eggs, flour, ground almonds, mixed spice and vanilla until well combined, then stir in the cooled fruit mixture and the pecans. Tip the batter into the tin and bake for 2 hrs until a skewer inserted into the middle comes out clean. If any wet batter clings to the skewer, bake for a further 10 mins, then check again. Cool in the tin for 15 mins, then put on a wire rack to cool fully.
