This Apple Streusel Cake is a great way to showcase the apple's delicious flavor and texture. It falls into the 'coffee cake' category as it combines a light and buttery cake with sliced apples and a streusel topping.
Preheat your oven to 350 degrees F (180 degrees C). Butter and flour an 8 inch (20 cm) spring form pan.
Streusel Topping: In a large bowl, mix together the flour, sugar, ground cinnamon, and salt. Cut the butter into the flour with a pastry blender or fork until it resembles coarse crumbs. Stir in the chopped nuts. Set aside while you make the cake batter.
In a separate bowl whisk together the flour, baking powder, and salt.
Note: To toast the pecans, walnuts or almonds. Put on a baking sheet and place in a 350 degree F (180 degree C) oven for about 8 minutes or until brown and fragrant. Let cool and then chop coarsely. If using hazelnuts place in the oven for 15 minutes or until fragrant and the skins begin to flake (peel). Remove from oven and cover the hot nuts with a clean dish towel. Let the hazelnuts (steam) for a about five minutes, then rub the nuts in the towel briskly to remove the skins. Let cool then chop coarsely.
