How come there's not vanilla bars like there are for chocolate?

We don't see vanilla bars as often as chocolate bars because of how we experience flavor and pleasure. Chocolate has compounds like theobromine and caffeine, which give it a mild stimulating effect, making it feel more exciting and energizing. Plus, its rich, complex flavor profile appeals to a wider range of tastes. Vanilla, on the other hand, is more subtle and lacks the same sensory punch, even though it’s a universally loved flavor.
