Combine flour, sugar, baking powder, and salt in a food processor or large bowl and mix well. Cut in the cold butter until mixture is fine and crumbly. Slowly add coconut milk or cream and mix until a dough forms. If it's a bit sticky add small amounts of flour until the dough is no longer sticky.

Cut your apples into quarters and remove the seeds. Cut each section into small squares. Pour the apples into a saucepan or skillet and place over medium high heat.

Add the butter and cook for about 5 minutes until apples begin to soften. Add the sugar and stir until melted. Sprinkle in remaining ingredients while stirring.

Cook over heat for about 3 minutes until it begins to thicken. Remove from heat and allow to cool.

In a mixing bowl stir together the brown sugar and melted butter. Add in the flour and salt and fold together with a spatula or use hand mixer to blend until it becomes a thick crumbly dough.

Preheat oven to 350 degrees F and line a baking tray with parchment.

Roll the chilled pastry dough into a rectangle as evenly as possible. Pour half of the crumb mixture and half of the apple mixture onto center of dough (horizontally) and press down slightly.

Fold top half of the dough up over the filling to completely cover. Pour the remaining filling onto second layer and fold the lower section of dough up to cover second layer of filling. Press down to seal the edges as well as possible.

Cut the slab into 4 sections and place on a parchment lined baking tray. Use a sharp knife or pastry cutter to cut each section diagonally to make triangles. Bake for 8 minutes then rotate pan and bake for 10 - 12 minutes longer until edges are golden. Remove from oven and allow to cool.
