Combine all ingredients in a pint glass with ice. Cover and shake vigorously for 15 to 20 seconds. Strain into a chilled Old Fashioned glass with large ice cubes. Garnish with a maple bacon strip.
Take a 750 ml bottle of Maker's Mark and 3 ounces of bacon fat. Combine cooled bacon fat and Bourbon in a large pitcher. Place at room temperature for about 6 hours. Place upright in a freezer and chill until the fat rises and solidifies into a sold disk. Remove from freezer and toss away fat. Double strain into a container that can use a pour spout. Keep for up to 4 weeks.
