01 - Preheat oven to 350°F and line a 12-cup muffin tin with paper liners.
02 - In a medium bowl, sift together flour, cocoa powder, baking powder, baking soda, and salt until well combined.
03 - In a large bowl, whisk eggs and sugar until light and fluffy. Add milk, vegetable oil, and vanilla extract; blend until fully incorporated.
04 - Gradually add dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix.
05 - Divide batter evenly among cupcake liners. Bake for 16-18 minutes, or until a toothpick inserted in the center comes out clean. Cool completely before frosting.
06 - Beat softened butter until creamy. Gradually mix in powdered sugar and cocoa powder. Add vanilla and 2 tablespoons milk; beat until fluffy and spreadable, adding more milk if needed.
07 - Generously frost the completely cooled cupcakes with the chocolate frosting, creating a smooth surface for decoration.
08 - Carefully twist Oreo cookies apart, keeping the cream filling on one half. Place two cream-side-up halves on each cupcake to form the owl's eyes.
09 - Press one brown candy onto the center of each cream-filled eye for pupils. Position an orange or yellow candy between the eyes as the beak. Optionally, place Oreo halves without cream on the upper corners as eyebrows.
10 - Arrange your whimsical owl cupcakes on a serving platter and enjoy these playful treats.
