Begin by coating a small loaf pan (measuring 8 x 4 inches) or a 7-inch/18 cm round cake pan with non-stick spray. Ensure even coverage. Next, preheat the oven to 400°F/299°C.
Take the flour, baking powder, and salt, and sift them together. Introduce the caraway seed into the mixture and set it aside.
In a separate bowl, beat the butter and sugar until the mixture achieves a pale consistency. Gradually add the eggs, one at a time, ensuring thorough blending after each addition.
Incorporate the flour mixture into the batter and adjust the consistency by adding sufficient milk. Aim for a dropping consistency akin to that of a pound cake. Note that the batter will possess a stiff texture.
Transfer the prepared batter to the greased pan, spreading it evenly. Place the pan in the preheated oven and bake for approximately 40-50 minutes, or until a toothpick inserted into the centre emerges clean.
