Step 1- Preheat the Oven
Preheat your oven to 200°C (400°F).
Step 2- Prep the Peaches and Spices
Thinly slice the peaches. In a small bowl, mix together the cinnamon and ginger powder and set aside.
Step 3- Line Your Baking Tray
Line a baking tray with parchment paper.
Step 4- Build Each Tart
Spread about 2 teaspoons of maple syrup on a corner of the parchment for each tart. Place peach slices on top, then drizzle with a bit more maple syrup. Sprinkle with the cinnamon-ginger mixture and a few sliced almonds.
Step 5- Cover and Seal
Cover with a puff pastry square and gently press down. Seal the edges by pressing with a fork all the way around.
Step 6- Brush with Oil
Brush the puff pastry with a little oil, then repeat the process with all the remaining squares.
Step 7- Prick and Bake
Prick each puff pastry square in 2 to 3 places with a fork to let steam escape. Bake in the preheated oven for 18 to 20 minutes, or until the pastry turns golden brown.
Step 8- Cool and Flip
Remove the baking tray and let the tarts cool to room temperature. Once cooled, flip them over with a spatula so the peach filling faces up.
Step 9- Garnish and Serve
Sprinkle with powdered sugar and a few extra sliced almonds before serving.
