Mix flour, yeast, milk, eggs, sugar, butter, raisins, lemon peel, cinnamon and/or cardamom, and salt to form a dough. Knead until smooth, adding more flour for kneading as needed.
Let the dough rise in a warm place until roughly doubled in size.
Divide the dough into portions and shape each into a flat cake roughly saucer-sized or slightly larger, using the heel of your hand. Place on a baking sheet.
Bake for 20 minutes at 200°C (392°F) using top and bottom heat, or at 170°C (338°F) using fan heat, until golden.
While still hot, brush each cake with butter using a butter block, allowing the butter to soak in.
Cool completely. Once cooled, freeze individually in a bag and thaw quickly as needed.
