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.
- To make the streusel topping – sift the flour and cinnamon together. I just whisked them together well since I didn’t have a sieve.
- Cut the cold butter into small pieces and rub into the flour+cinnamon mixture with fingertips until the streusel comes together like bread crumbs.
- Add the brown sugar to this.
- Mix well and set aside until needed.
- 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.
- Add the sugar to this and cream together until well combined and soft.
- Add the egg and vanilla.
- 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
- 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.
- Layer the sliced apples on top. You can make this layer as thick or thin as you like.
- Sprinkle the streusel on top.
- 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.
