01 - Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.
02 - In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and pumpkin pie spice.
03 - In a large bowl, whisk together the vegetable oil and granulated sugar until combined. Add the eggs, pumpkin puree, and vanilla extract; whisk until the mixture is smooth.
04 - Gradually add the dry ingredients to the wet mixture. Stir until just combined, taking care not to overmix the batter.
05 - Divide the batter evenly among the prepared cupcake liners. Bake for 18–20 minutes, or until a toothpick inserted into the center of a cupcake comes out clean. Allow the cupcakes to cool completely.
06 - For the cream cheese frosting, beat together the softened cream cheese and softened butter until smooth. Gradually incorporate the powdered sugar, vanilla extract, and salt until the frosting is light and fluffy.
07 - Generously frost the cooled cupcakes with the prepared cream cheese frosting.
08 - Assemble the "rat" decorations on each cupcake. Position a chocolate truffle or donut hole as the rat's body. Attach two mini chocolate chips or candy eyes for the eyes, a pink candy for the nose, and almond slices for the ears. Finally, add thin licorice strings for the tails and whiskers, pressing gently to secure them.
