Preheat your oven to 325°F (163°C). Grease a 9-inch springform pan.
In a medium bowl, combine the crushed graham crackers, melted butter, and 2 tablespoons of sugar. Mix until well combined. Press the mixture firmly into the bottom of the prepared springform pan to form the crust.
In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth. Gradually add 1 cup of sugar and continue to beat until creamy.
Add the vanilla extract, eggs, cocoa powder, and red food coloring to the cream cheese mixture. Beat until fully incorporated and smooth.
Mix in the sour cream until just combined. Do not overmix.
Pour the cheesecake batter over the prepared crust in the springform pan. Smooth the top with a spatula.
Bake in the preheated oven for 50-60 minutes, or until the center is set but still slightly jiggly. Turn off the oven and leave the cheesecake inside for an additional hour to cool gradually.
Remove the cheesecake from the oven and let it cool completely at room temperature. Once cooled, refrigerate for at least 4 hours or overnight.
Before serving, spread the strawberry jam evenly over the top of the cheesecake and arrange the sliced strawberries on top.
