Creating the Summer Berry and Peach Cheesecake involves several steps but is manageable with a little patience. Follow these instructions closely for perfect results:

1. Preheat the Oven: Start by preheating your oven to 325°F (160°C).

2. Prepare the Crust: In a mixing bowl, combine the graham cracker crumbs, cocoa powder, sugar, and melted butter. Mix until well combined and crumbly.

3. Form the Base: Press the crumb mixture firmly into the bottom of a 9-inch springform pan to form an even layer. Bake in the preheated oven for 10-12 minutes. Remove and let cool while preparing the filling.

4. Make the Cheesecake Filling: In a large bowl, beat the softened cream cheese and sugar until smooth and creamy. Add in vanilla extract and mix again.

5. Mix in Eggs: Add one egg at a time, mixing well after each addition until fully incorporated.

6. Add Sour Cream: Stir in the sour cream until the mixture is smooth and free of lumps.

7. Pour Filling: Once the crust has cooled, pour the cheesecake filling over the crust, smoothing the top with a spatula.

8. Bake the Cheesecake: Place the springform pan in the oven and bake for 50-60 minutes, or until the center is set but still slightly jiggly.

9. Cooling: Turn off the oven and leave the cheesecake in the oven with the door slightly ajar for about 1 hour. Then, transfer to the refrigerator to chill for at least 2-3 hours.

10. Prepare the Fruit Topping: While the cheesecake chills, prepare the fruit topping. If desired, gently toss the sliced peaches and mixed berries with honey for added sweetness.

11. Assemble: Once the cheesecake is fully chilled, remove it from the springform pan. Top with the peach slices and mixed berries, arranging them artfully for a beautiful presentation.

12. Garnish: Optionally, garnishing with fresh mint leaves adds a pop of color.
