Mix step 1 into step 2 a little at time, using spatula. Do this gently so batter wont deflate much.
Take out a couple tbsp of batter and add food coloring (depending what you want to make, this one I made strawberry, so food colors are accordingly). Pour into piping bag, and pipe of baking sheet which already lined with parchment paper. Bake on preheated 325 F for 1-2 mins.
Pour the rest of the batter covering strawberry patterns and bake for 15-18 mins
Take out, flip on another parchment paper, and gently peel the patterned parchment paper.
Roll gently immediately and leave to cool. Unroll, fill with your faved. filling and reroll.
Pictured was with whipped cream - best once filled, chill for a couple of hours before slicing.
