Preheat oven to three hundred and fifty.
Line a large baking (cookie) sheet with parchment paper. It’s a good idea to spray a small amount of cooking oil on the parchment paper to ensure no sticking.
In a large bowl, combine the eight eggs, one and one-quarter cups of sugar, two teaspoons of vanilla, and two tablespoons of vegetable oil.
In a separate bowl blend two cups of Bisquick, two teaspoons of baking powder, one teaspoon salt, and ½cups of cocoa powder.
Mix the wet and dry ingredients together with an electric beater for approximately four minutes.
Place the batter on the greased baking sheet and bake for approximately twelve to fifteen minutes.
Sprinkle a tea towel with one-quarter cup of powdered sugar.
Remove the cake from the sheet and place it onto the towel, removing the parchment paper. Fold the edge of the towel over the edge of the cake and roll with the towel. Place in fridge until cool.
Unroll the cake once it has cooled and remove the towel. Spread the filling over the top of the cake and layer the strawberries evenly.
Gently roll the cake and sprinkle with a small amount of powdered sugar (optional). Place seam down and cool in the refrigerator for approximately an hour before serving.
