Preheat the oven to 350°F (175°C). Lightly grease a 9x13-inch baking pan with nonstick spray or line with parchment paper.
In a large bowl, whisk together the flour, baking powder, baking soda, salt, and pumpkin pie spice until well combined.
In a separate bowl, beat the eggs, granulated sugar, and brown sugar with a hand mixer until pale and fluffy, about 2 minutes. Add the oil, pumpkin puree, and vanilla, and mix until combined. Add the dry ingredients and mix on low just until no streaks of flour remain.
Pour the batter into the prepared pan and spread evenly. Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely in the pan on a wire rack, about 45 minutes.
Once the cake is completely cool, crumble it into fine, even crumbs in a large mixing bowl, breaking up any larger chunks.
In a medium bowl, beat the softened cream cheese and butter together until smooth. Add the powdered sugar and vanilla, and continue beating until creamy with no lumps.
Add the cream cheese binder to the crumbled cake a few spoonfuls at a time, mixing after each addition, until the mixture holds together when pressed but is not sticky or wet.
Use a cookie scoop to portion the mixture, then roll each portion between your palms into a smooth ball about 1 to 1.5 inches wide. Place on a parchment-lined baking sheet and freeze for 15 minutes, or refrigerate for 30 minutes, until firm.
Melt the orange candy melts in a candy melting pot or microwave in 30-second bursts, stirring between each, until smooth. Stir in a small amount of coconut oil or shortening if the coating is too thick.
Dip the tip of each cake pop stick into the melted coating, then insert it about halfway into a chilled cake ball. Dip each ball fully into the coating, gently tapping the stick against the pot to remove excess. Stand upright in a cake pop stand or styrofoam to set.
Melt the chocolate candy melts separately using the same method. Once the orange shell has set, drizzle each pop with melted chocolate and immediately sprinkle with crushed graham crackers or sprinkles. Let sit until completely set, about 20 minutes at room temperature.
