An exquisite Caramel Pecan Brittle Swiss Roll that is well worth making the effort to bake. Topped and filled with a cream cheese frosting and crushed homemade Caramel Pecan Brittle. A final touch of whole Pecan nuts will make you come back for another slice.
Line a baking sheet with baking parchment. Put the sugar and 35ml of water into a heavy-bottomed pan and gently heat until the sugar has dissolved. Bring the syrup to a boil until it begins to turn a golden caramel colour. Keep watching it. Remove from the heat and carefully add the chopped nuts. Give the pan a swirl – don’t stir, making sure the nuts are coated in the caramel, then pour on to the baking parchment allowing it to find its own level. Leave to set and cool completely.
When cool, break the brittle into chunks before blitzing in a food processor until you have fine crumbs. Leave to one side until required.
Make the Swiss Roll Sponge
Preheat the oven to 180 C/fan 160 C/gas 4. Grease and line a 32 x 23cm Swiss roll tin.
Beat the egg yolks, brown sugar and vanilla seeds using a wooden spoon or electric whisk, until thick and creamy and much lighter in colour.
In a clean bowl, whisk the egg whites until soft peaks form. Continue whisking as you slowly add the caster sugar until you have stiff peaks. Gently fold a little of the egg white into the yolk mixture to loosen it, then fold in two thirds of the egg white, then the flour and finally the remaining egg white.
Carefully pour the batter evenly into the tin and bake for 8–10 minutes or until a skewer inserted in the centre comes out clean. Leave in the tin to cool for a few minutes, then place a fresh sheet of baking parchment on top of the sponge and turn it out. Remove the old parchment. Beginning at the shorter end, roll up the sponge, including the paper. Leave rolled until it is cool.
Make the Creamcheese Filling
Mix together the cream cheese, icing sugar and vanilla seeds. In a separate bowl, whip the cream until soft peaks form. Gradually add this to the cream cheese mixture and mix until combined. Do not overmix.
Unroll the sponge, leaving it laid out on the baking parchment, then spread half the filling over it. Scatter over the chopped pecans, followed by a large handful of the crushed caramel brittle.
Starting with the shorter end, and with the aid of the baking parchment, start to roll the sponge around the filling. Place the remaining filling in a piping bag fitted with a rosette nozzle and pipe rosettes on top of the roll. Scatter more brittle over the whole cake and decorate with the pecan halves.
This cake will keep for a couple of days and is best kept in the fridge.
