Add bourbon, maple syrup, angostura bitters, and orange bitters to a mixing glass.
Add ice and stir for about 20 seconds to chill.
Strain into a rocks glass over a large ice cube.
Top with ginger beer and stir gently to mix.
Twist orange peel over glass, then add as garnish. Add cinnamon stick or cherry if desired.
Notes
Use rye whiskey for more spice. Adjust maple syrup for sweetness. Ginger beer brings fizz and warmth—don't shake, just stir gently. Garnish with orange, cinnamon, or cherry for a cozy touch.
