Creating your Christmas Vanilla Roll Cake is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C). Line a 15×10-inch jelly roll pan with parchment paper, allowing some overhang for easy removal.
2. Prepare Egg Mixture: In a mixing bowl, beat the eggs on high speed for about 5 minutes, until thick and pale. Gradually add granulated sugar and vanilla extract, mixing until well combined.
3. Mix Dry Ingredients: In another bowl, sift together the flour, baking powder, and salt.
4. Combine Mixtures: Gently fold the dry ingredients into the egg mixture, being careful not to deflate the batter.
5. Bake: Pour the batter into the prepared pan, spreading it evenly. Bake in the preheated oven for 15-20 minutes or until the cake springs back when touched.
6. Cool the Cake: Once baked, remove the cake from the oven. Carefully invert it onto a clean kitchen towel dusted with powdered sugar. Gently peel off the parchment paper.
7. Roll the Cake: While the cake is still warm, roll it up tightly in the towel, starting from the short end. Allow it to cool completely in this position.
8. Prepare the Filling: In a mixing bowl, whip the heavy cream, powdered sugar, and vanilla extract until soft peaks form.
9. Unroll and Fill: Once the cake is cool, unroll it gently. Spread the whipped cream filling evenly over the cake.
10. Re-roll the Cake: Roll the cake back up without the towel, ensuring it’s tight but not squished. Place it seam-side down on a serving platter.
11. Decorate: Optionally, dust the top with powdered sugar and add sprinkles for a festive touch.

With these steps, you’ll have a stunning and delicious Christmas Vanilla Roll Cake ready to impress your guests!
