First, keep it at room temperature and whip the softened butter with a whisk to make it soft.

Add sugar and whip for at least 10 minutes.

If a soft and rich butter cream is made

Add eggs stored at room temperature one at a time and keep whipping. The longer you whip, the softer the cake will be.

I'll divide the dough into two, one with coffee extract and Kahlua
I made the dough with lemon juice and lemon extract,

Add the sifted flour more than twice and mix lightly with a rubber spatula to knead.

I squeezed the dough into a bag and panned it in a mold
If you scoop it with a spoon, it gets dirty in the mold, so I usually put it in a squeezer and pan it. If you put chopsticks in the dough and turn it like this, you will get less holes. Bake in a preheated 180 degrees oven for 35 to 40 minutes
If the top gets darker, cover it with foil and bake it so that it doesn't burn. After baking, remove molds, cool in a cooling net, place in a plastic pack, seal, and store for one night before eating for a softer pound cake.
