Preheat your oven to 180°C (350°F).
Grease a 2-pound loaf pan with butter, dust it with some flour, then set it aside.
Using a large mixing bowl, mix softened butter and sugar until creamy.
Add the eggs one at a time while mixing in between.
Once all the eggs have been added, strain and add the flour and baking powder.
Add the caraway seeds and vanilla extract, and fold gently into the batter --- just enough to combine with the rest.
Pour the seed cake batter into the prepared pan from earlier.
Sprinkle more caraway seeds on top.
Place the loaf pan in the lower part of the oven for 40 to 45 minutes or until a toothpick comes out clean when inserted into the cake.
Remove from the oven and set aside for about 15 minutes to cool.
Your English seed cake is now ready for serving!
