Base

• 1 cup (240 ml) commercially-prepared baking mix or biscuit mix
• ¼ cup brown sugar
• 1 egg
• 1 ounce (30 g) butter
• ½ teaspoon cinnamon powder
• ¼ teaspoon powdered ginger
• ¼ teaspoon ground nutmeg

Topping

• 2 soft-textured apples, sliced
• 1 splash of grapefruit or lemon juice
• ½ teaspoon cinnamon powder
• ¼ teaspoon powdered ginger
• ¼ teaspoon ground nutmeg
• 3 tablespoons baking mix or biscuit mix
• 3 tablespoons brown sugar

Make base

1. Combine the baking mix, egg, brown sugar, and spices in a bowl.
2. Rub the butter into the base mixture with your fingers. The mixture should not be sticky.
3. Line an 8 by 8-inch (20 by 20 cm) baking pan with parchment paper.
4. Press the base mixture into the bottom of the baking pan (you might want to press it up the sides a little).

Prepare topping

5. Toss the sliced apples in the grapefruit or lemon juice, distributing the juice evenly.
6. Combine the cinnamon, ginger, nutmeg, baking mix, and brown sugar.
7. Toss most of the spice mix with the apples. Reserve the remaining spice mix.
8. Tip the lightly coated apples on top of the prepared base in the pan. Try to arrange the slices to have an even layer.
9. Sprinkle the remaining spice mixture on top of the apples.

Bake

10. Preheat oven to 375°F (190°C).
11. Bake for 30 minutes at 375°F (190°C).
12. After allowing it to cool, you can lift the slice out of the baking pan by the corners of the parchment paper and put it on a plate for easy slicing.
