When does streusel not make something better?

I have made these without the streusel though and used a scant cup of raisins.

I have also used both.

Streusel mixture

Prep time – 10 minutes

¼ cup (50g) cane sugar
⅓ cup (76g) butter, cold, cut in pieces to make it easier to add. At least 9 pieces.
¼ cup (34g) flour
⅓ cup (30g) rolled oats
1 tsp cinnamon
⅛ tsp salt, if using unsalted butter

Combine the sugar, flour, oats and cinnamon.
Cut in the cold butter with a pastry cutter, or two knives. A food processor works great, but just until crumbly.
