A very tasty and fluffy (you could even say spongy) muffin topped with yummy crumbs... What more can you ask for?! :)
- In a big bowl combine flour and baking powder. Add sugar, vanilla, eggs, butter, poppy seeds and crème fraiche. Using a mixer work into a smooth dough (will take about 2 minutes).
- Take 3-4 heaped tbs of the dough and place in a second bowl. Add as much of the additional flour as needed to make coarse crumbs (they shall be rather soft).
- Fill dough into prepared muffin pans and top with crumbles.
- Bake in the preheated oven at 180°C for about 25 minutes.
