All-purpose flour 2 cups
Preheat the oven to 350°F
For extra dimension, combine two apple varieties—one tart (Granny Smith) and one sweet (Honeycrisp or Fuji)—so the filling stays bright yet naturally sweet without extra sugar. If you like a crunchier topping, sprinkle a handful of toasted chopped pecans over the streusel before baking; they’ll toast further in the oven and add buttery depth.
