The specific operations are as follows:

1. Fold the square colored paper in half and then in half again. After opening, there will be a cross crease inside. Then fold the left and right sides in half towards the middle crease, then fold the top and bottom sides in half towards the center line, unfold the colored paper, tuck the four corners inward, as shown in the picture, press out the crease and then unfold it.

2. Along the creases at the four corners, gather them inward one by one to form a square. The finished product after folding is as shown in the picture. You need to prepare 4 identical squares.

3. Place one square piece of paper on top of the other at an angle. As shown in Figure 1. Then first collect the four lower corners and fold them upward, and then fold the four upper corners upward. Take the top off. Stick double-sided tape on the inner corner of a square paper, tear it off, press the other one back in, and retract the corners.

4. Take the other two square pieces of paper, taking the lower center as the center, and fold them in half. After folding it in half, stretch it out and flatten it.

5. Prepare a square piece of paper of the same size, fold it in half, and cut it into 2 rectangles. After pasting the edges, form a circle toward the inside of the cake base and cut off the excess.

6. Fold the upper and lower sides in half to a length of 1 cm, and stick double-sided tape on the top. Use a ballpoint pen to mark the upper glue at intervals of 0.5cm.

7. Tear off the double-sided tape at the bottom and stick it to the bottom tray of the cake. Then tear off the double-sided tape on top and put the other folded finished product on it and stick it on.

8. Stick double-sided tape on the bottom of the candle and place it on the cake.

A cupcake is now folded. Birthday cakes first originated in the West and were later introduced to China. The earliest cakes were made from a few simple ingredients. These cakes were symbols of ancient religious myths and miraculous superstitions.
