Follow these simple steps to create your amazing Christmas Vanilla Roll Cake:

1. Preheat the Oven: Preheat your oven to 375°F (190°C). Line a 15×10-inch jelly roll pan with parchment paper and lightly grease it.
2. Beat Eggs and Sugar: In a large bowl, beat the eggs and granulated sugar until pale and fluffy, about 5 minutes. Add vanilla extract and mix well.
3. Combine Dry Ingredients: In a separate bowl, sift together the flour, baking powder, and salt.
4. Fold Dry Ingredients: Gently fold the dry ingredients into the egg mixture, being careful not to deflate the batter.
5. Pour Batter: Spread the batter evenly in the prepared jelly roll pan.
6. Bake: Bake in the preheated oven for 15-20 minutes or until the cake is lightly golden and springs back when touched.
7. Cool the Cake: Remove from the oven and let it cool in the pan for 5 minutes. Then, turn it out onto a clean kitchen towel dusted with powdered sugar.
8. Roll the Cake: Carefully roll the cake with the towel from the short end, creating a log shape. Allow it to cool completely in this position.
9. Prepare the Filling: In a mixing bowl, whip the heavy cream with powdered sugar until stiff peaks form. Add additional vanilla extract if desired.
10. Unroll the Cake: Once cool, gently unroll the cake and spread the whipped cream evenly over the surface.
11. Re-roll the Cake: Roll the cake back up without the towel and place it seam-side down on a serving platter.
12. Chill: Refrigerate for at least 30 minutes to allow the filling to set.
13. Garnish: Before serving, dust with powdered sugar and garnish with fresh berries if desired.
