  1. Frosting Preparation: In a microwave-safe bowl, combine white chocolate chips, heavy cream, and peppermint extract. Microwave at half power in intervals of 30 seconds, stirring after each until smooth. Chill uncovered until fully set, about 1 hour.
  2. Preheat Oven: Set your oven to 350°F (175°C). Line an 8×8-inch square pan with parchment paper, ensuring an overhang on all sides.
  3. Dissolve Espresso Powder: Mix the espresso powder with hot water until it fully dissolves.
  4. Combine Dry Ingredients: In a medium bowl, whisk together flour, cocoa powder, salt, baking soda, and baking powder.
  5. Cream Butter and Sugars: In a large bowl, beat the butter with both sugars until light and fluffy. Beat in the egg thoroughly. Mix in the espresso solution, vanilla extract, and peppermint extract.
  6. Forming the Dough: Gradually mix in half the flour mixture until just blended. Add the remaining flour mixture, mixing just until combined. The dough will be thick. Stir in the chocolate chips and crushed candy canes. Spread the dough evenly in the prepared pan.
  7. Baking: Bake for 25-30 minutes, or until the bars are set. Allow them to cool completely in the pan.
  8. Frost the Bars: Whip the chilled white chocolate mixture until it forms stiff peaks. Spread this frosting over the cooled bars and sprinkle with extra crushed candy canes.
  9. Serving: Cut into 16 pieces and serve.
