Baking disaster: Classic streusel blueberry muffins

I completely messed up the streusel and the oven temperature:  adding too much flour to the streusel; not massaging the streusel with two hands; and baking the muffins at 280'C instead of 190'C for 35 minutes.

(I baked the muffins for 10 minutes before smelling the burnt streusel from the oven!  The kitchen was covered with smoke!!!)

The result was muffins covered with burnt streusel.  The saving grace out of this trial was the texture of the muffins.  They were soft and fluffy due to the sieving process and milk.  Another one was the tulip wraps, that were correctly home made by me!

I will follow the instruction for the muffins in the future.  Enjoy the photos below.
