01 - Whisk flour, granulated sugar, baking powder, baking soda, and salt together in a medium bowl.
02 - In a separate bowl, beat eggs. Add whole milk, cooled brewed coffee, melted unsalted butter, and pure vanilla extract; whisk until homogenous.
03 - Stir wet mixture into dry ingredients gradually, blending just until incorporated. Avoid overmixing; a slightly lumpy texture is ideal.
04 - Heat nonstick pancake pop pan, cake pop maker, or skillet over medium-low. Lightly grease with unsalted butter.
05 - Deposit 1 tablespoon batter per pop onto prepared surface. Insert a wooden lollipop stick into each portion before turning.
06 - Allow pops to cook for 1–2 minutes until bubbles appear and edges set. Flip carefully; cook an additional 1–2 minutes until golden and fully set.
07 - Transfer cooked pops to a plate. Continue process with remaining batter, regreasing the pan as necessary.
08 - Allow pops to cool slightly. Dust with powdered sugar if desired. Serve while warm.
