In a mixer bowl, mix the dry ingredients - flour, sugar, baking powder, and poppy seeds.

Add the softened butter in portions and mix on low speed.

Add the lukewarm milk, mixing on low speed.

Add eggs one by one and yogurt - mix only until combined - do not overmix, as it may result in a dense, uncooked layer.

Pour the batter into the prepared pan.

Bake at 180 degrees (top/bottom heat) for 30-35 minutes - until a wooden skewer comes out clean.

After baking, let it cool slightly.

Prepare the glaze - pour the sugar into a bowl and add heavy cream or milk, one tablespoon at a time - the glaze should be thick but slightly pourable.

Spread the glaze over the cake - you can additionally sprinkle the top of the cake with dry poppy seeds.
