What's inside makes a difference

Peanut butter

Peanut butter

Peanut butter adds rich, satisfying flavor plus fats and protein that help the bar feel more filling. It’s one of the ingredients that gives Kate’s that creamy, comforting base.

Why we love it:

  • Whole-food fat source
  • Satisfying, steady fuel
  • Simple, recognizable ingredient
Honey

Honey

Honey is a natural source of carbohydrates that helps deliver quick energy when you need it. It also adds sweetness and binds the bar together without relying on refined syrups.

Why we love it:

  • Naturally sweet
  • Quick energy source
  • Simple, recognizable ingredient
Ingredient Icon
Oats

Oats

Oats provide slow-release carbs that support steady energy and lasting fullness. Their soluble fiber helps slow digestion, which supports a more even, sustained feeling of fuel.

Why we love it:

  • Gentle on the stomach
  • Whole-grain energy source
  • Simple, recognizable ingredient

Plant-based protein

Plant-based protein

Plant-based protein helps the bar feel more satisfying and supports longer-lasting fullness. It’s what turns this into a protein bar that can hold up through long days, not just a quick snack.

Why we love it:

  • Helps you stay satisfied
  • Steadier, longer-lasting fuel
  • Simple, recognizable ingredient
Dark chocolate

Dark chocolate

Dark chocolate brings a deeper cocoa flavor with less sweetness than milk chocolate. It adds richness and contrast that keeps the bar tasting bold without being sugary.

Why we love it:

  • Rich cocoa taste
  • Less sweet finish
  • Simple, recognizable ingredient
