An Original Klondike Bar Has 250 Calories
One Original Klondike bar (85 g) has 250 calories. Compare other varieties and calculate half-bar, two-bar and six-pack totals.
One Original Vanilla Klondike bar (85 g) has 250 calories, including the chocolatey coating. That is the serving listed for the U.S. six-count multipack—not the calorie total for the whole box. Klondike’s Original nutrition listing gives the serving as one bar.
If you ate the classic vanilla square with its coating, 250 calories is the number to log, unless your package lists a different value. Other Klondike varieties have their own serving weights and calorie counts.
Calories by variety
These U.S. manufacturer listings were checked on October 1, 2026. All refer to servings from six-count multipacks.
| Klondike variety | Listed serving weight | Calories per serving |
|---|---|---|
| Original Vanilla | 85 g, one bar | 250 |
| Dark Chocolate | 85 g | 250 |
| Heath | 74 g, one bar | 230 |
| No Sugar Added Vanilla | 74 g, one bar | 180 |
The comparison is per listed portion, not equal weight: the Heath and No Sugar Added Vanilla bars are lighter than the Original. Also, “no sugar added” does not mean calorie-free—the listed bar still supplies 180 calories.
Half a bar, two bars or the whole box
Using the Original’s 250-calorie label value:
| Amount eaten | Calories |
|---|---|
| Half a bar | About 125 |
| One bar | 250 |
| Two bars | 500 |
| All six bars in a six-pack | 1,500 |
These are calculated totals. The half-bar estimate assumes you eat roughly half of both the filling and coating.
For tracking, match the variety, serving weight and number of bars before choosing an entry. Do not add the coating separately; it is already included in the whole-bar value. If the wrapper or carton differs from an online listing, use the nutrition panel on the package you actually ate.
