Ingredients
320 g (11 oz) unsalted butter, melted and cooled
320 g (11 oz) soft light brown sugar
4 eggs
320 g (11 oz) plain (all-purpose) flour
2 teaspoons bicarbonate of soda (baking soda)
1 teaspoon ground cinnamon Pinch of salt
100 g (3½ oz) peeled and grated parsnip
200 g (7 oz) peeled and chopped pears
½ tablespoon finely chopped rosemary, and sprigs to decorate
125 g (4½ oz) unsalted butter
200 g (7 oz) icing (confectioners’) sugar
2 teaspoons ground cinnamon
50 ml (1½ fl oz) thick (double/heavy) cream
Instructions
1Preheat the oven to 170°C (335°F). Grease and line two 15 cm (6-inch) round cake tins.
2Beat the melted and cooled butter, brown sugar, and eggs together with an electric mixer for 2 minutes until pale and fully combined.
3Sift the flour, bicarbonate of soda, and salt into a clean bowl. Fold this dry mixture into the beaten butter mixture by hand until just combined. Overmixing will make the cake tough.
4Fold the grated parsnip, chopped pear, and chopped rosemary into the batter. Divide the batter evenly between the two tins.
5Bake for 40 to 50 minutes, or until a skewer inserted into the center comes out clean. Transfer the cakes to a wire rack and let them cool completely before frosting. Warm cakes will melt the buttercream.
6Make the frosting by beating the remaining 125 g (4½ oz) butter for 3 to 4 minutes until pale and creamy. Add the icing sugar, cinnamon, and cream, mixing until completely smooth.
7Trim the domed tops off the cooled cakes to level them, then slice each cake horizontally to create four even layers.
8Place the first layer on a serving plate and spread or pipe a portion of the buttercream over it. Stack the next layer and cover with buttercream, repeating until all layers are stacked. Spread a final layer of buttercream over the top and garnish with fresh rosemary sprigs.
Notes
Storage: Keep the frosted cake in the fridge for up to 3 days. Let it sit at room temperature for 30 minutes before serving so the buttercream softens.
Make ahead: You can bake the cake layers a day in advance. Wrap them tightly in plastic wrap and store at room temperature until you're ready to frost.
Tip: Make sure your melted butter has cooled completely before mixing it with the eggs, or it might scramble them.
