Spiced Jelly Roll Cake With Honey Buttercream Filling - cooking recipe

Ingredients

4 None eggs, separated
1/2 cup granulated sugar, plus extra to dust
2/3 cup cornstarch
2 tbsp all-purpose flour
1 tsp pumpkin pie spice
1/2 tsp ground cinnamon
2 tsp baking powder
1/4 cup honey
6 1/2 tbsp unsalted butter

Preparation

Preheat oven to 350\u00b0F. Lightly grease and line base and sides of a 10x13 inch jelly roll pan with parchment paper.
Whip egg whites to firm peaks. Add sugar, 1 tbsp at a time, beating constantly, until mixture is thick and glossy. Beat in egg yolks until just combined. Sift together cornstarch, flour, spices and baking powder then fold into egg mixture along with 1 tbsp honey. Transfer to prepared pan and bake for 20 mins, until firm when lightly pressed with a fingertip.
Turn out onto a tea towel lightly dusted with sugar. Discard parchment paper and trim edges. Roll up immediately in the tea towel, starting from short edge. Set aside to cool.
Meanwhile, beat butter until pale and creamy. Add remaining honey and beat until combined. Add 2 tbsp water and continue beating until mixture is smooth and creamy. Unroll cake and spread filling over top. Roll up again and cut into slices to serve.
