Creating Strawberry Shortcake Sushi Rolls is simple if you follow these steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C) and greasing a rectangular baking pan.
2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, and salt until well combined.
3. Cream Butter and Sugar: In another bowl, cream the softened butter and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs, one at a time, followed by the vanilla extract until mixed well.
5. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, stirring until just combined.
6. Bake the Cake: Pour the batter into the prepared baking pan, spreading it evenly. Bake for 20-25 minutes or until a toothpick comes out clean.
7. Cool the Cake: Once baked, let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
8. Prepare Whipped Cream: In a bowl, whip the heavy cream and powdered sugar until stiff peaks form.
9. Slice the Cake: Once cooled, slice the cake into rectangular sheets that are about 6 inches wide.
10. Assemble the Rolls: Lay a sheet of nori or rice paper down, place a piece of cake on top, spread a layer of whipped cream, and add sliced strawberries.
11. Roll It Up: Carefully roll the cake, nori, and filling tightly like a sushi roll. If using rice paper, wet the edges to seal.
12. Chill the Rolls: Place the rolls in the refrigerator for at least 1 hour to firm up before slicing.
13. Slice and Serve: Use a sharp knife to cut the rolls into bite-sized pieces.
