8.
Drawing patterns: preparing patterns. When making the pattern, pay attention to the front and back, otherwise the finished pattern will be reversed. Lay the cut baking paper on the pattern and fix it with a paper clip or clip to prevent it from shifting. Draw contour lines according to the pattern under the paper and put it in the refrigerator for a while
9.
Take it out and fill in the color. Try not to leave a gap between the color and the color. After drawing, you can gently lift the baking paper and look at the reverse side, and deal with any bubbles. Then put the pattern in the refrigerator and chill until it is completely solidified
10.
After refrigerating to completely set, gently remove the parchment paper and put it in the baking tray to continue refrigerating

Use a spatula to wipe the surface of the flat paste, tap the baking pan to shake out the air, put it in a preheated 180 degree oven, and bake for 18 minutes. The toothpick is inserted into the cake and the cake is clean and the baking is complete.
18.
Take out the baked cake rolls, cover the baking pan with a baking net, turn the cake rolls upside down, and tear off the oily paper at the bottom
19.
Then cover it gently with a piece of clean greased paper
20.
Re-lay new greased paper on the countertop, pour down the cake slices that have been dried until warm (surface upwards), and spread the fillings evenly.
21.
Roll up the cake with the help of a rolling pin (the specific operation can be made by Baidu to make a video of cake rolls), seal both ends, put it in the refrigerator for more than 1 hour to set the shape
Tips:
1. Generally, it is better to use the slender type for the color-painted rolls.
2. When the cake slices are baked to dissipate heat, they must be covered with a clean greased paper. This way the surface of the cake is moisturized and it is not easy to crack when rolled
3. The filling must be enough to make the cake roll thicker; if the roll is thin and tight, the surface pattern is easy to crack. (Ignore this item if the pattern is small)
4. Pay attention to the front and back when making the pattern, otherwise the finished pattern will be reversed
