Jelly Roll Cake

Step 1: Heat your oven to 375° Fahrenheit.

Step 2: You need a 15X10X1 inch pan. Line it with either waxed paper, foil, or parchment paper. If using the waxed paper or the foil, you will need to grease it well.

Step 3: Add the three eggs to a medium bowl and beat them with an electric mixer until thick and lemon colored- about 5 minutes. Don't try to hurry this step because it will help the cake hold together.

Step 4: Beat in the granulated sugar. On low speed, beat in the water and vanilla.

Step 5: Add the flour, baking powder, and salt. Beat just until the batter is smooth.

Step 6: Pour the batter into the pan, making sure you spread it to the corners.

Step 7: Put into the oven and bake for 12 to 15 minutes or until a toothpick inserted in the middle comes out clean.

Step 8: Immediately loosen the cake from the pan. Turn the pan upside down onto a towel that you have previously sprinkled with powdered sugar.

Step 9: Remove the paper or foil.

Step 10: If the edges of the cake are stiff, trim the edges off.

Step 11: While the cake is still hot, roll it up with the towel. Roll from the narrow end. Cool it on a cooling rack for 30 minutes.

Step 12: Unroll the cake, removing the towel. If needed, beat the jelly or jam with a fork to soften it. Spread the jelly over the top of the cake.

Step 13: Roll the cake up again. Sprinkle powdered sugar over the top.
