Pin Step by Step Instructions for Apple Streusel Cake: 0. Pre-heat oven to 170C / 340F. Grease an 8″ cake pan with butter and set aside. I used a deep Pyrex glass dish since which is all I had in hand. Worked perfect.

  1. To make the streusel topping – sift the flour and cinnamon together. I just whisked them together well since I didn’t have a sieve.
  2. Cut the cold butter into small pieces and rub into the flour+cinnamon mixture with fingertips until the streusel comes together like bread crumbs.
  3. Add the brown sugar to this.
  4. Mix well and set aside until needed.
  5. For the cake sponge – take the softened butter in a large enough bowl. My butter was still cold so I cut it into small pieces to speed up the softening process.
  6. Add the sugar to this and cream together until well combined and soft.
  7. Add the egg and vanilla.
  8. Beat well with a whisk until combined. You can also use an electric beater or stand mixer but it’s not really needed. Then add the milk and mix well
  9. In a bowl, whisk the flour, salt, and baking powder together. Add this to the egg mixture in 3 additions and whisk the batter gently. Pour into the greased pan.
  10. Layer the sliced apples on top. You can make this layer as thick or thin as you like.
  11. Sprinkle the streusel on top.
  12. Bake in the pre-heated oven for 35-40 mins or until a skewer inserted into the centre comes out with moist crumbs. Cool and cut into slices. Apple streusel cake tastes great with a dollop of vanilla ice cream or vanilla flavoured sweetened yogurt.
