A moist and flavorful apple cake with a delightful cinnamon nut filling.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated for even baking.
In a bowl, mix the apples, cinnamon, and sugar for the filling. Set aside.
Let the filling sit for a few minutes to allow the flavors to meld.
In a large bowl, combine the flour, sugar, baking powder, and salt. Add the eggs and vanilla extract, and mix until smooth.
Mix just until combined to avoid overworking the batter.
Fold in the chopped walnuts and pecans into the batter.
Coat the nuts in a bit of flour before folding to prevent them from sinking.
Pour half of the batter into a greased tube pan. Layer half of the filling over the batter. Repeat with the remaining batter and filling.
Spread the layers evenly for a uniform bake.
Bake in the preheated oven for 1 hour and 20 minutes, or until a toothpick inserted in the center comes out clean.
Check the cake at the 1-hour mark to prevent overbaking.
Cool the cake in the pan for 15 minutes, then turn it out onto a wire rack to cool completely.
Run a knife around the edges of the pan to help release the cake.
Slice and serve the cake. Enjoy!
Serve with a dollop of whipped cream or a scoop of ice cream for added indulgence.
