In a bowl, combine the flour, sugar, salt, and yeast.

In a separate bowl, whisk the egg and warm milk together, then mix in the softened butter.

Pour the wet ingredients into the dry ingredients and knead until a smooth dough forms.

Let the dough rise in a warm place for about an hour, or until it doubles in size.

Preheat the oven to 180°C (350°F).

Roll out the dough and cut it into small circles; place a strawberry in the center of each circle.

Fold the dough over the strawberry and seal the edges.

Place the bombs on a baking sheet lined with parchment paper.

Bake for 15-20 minutes or until golden brown.

Allow to cool slightly before serving.
