No-Bake Oat & Peanut Butter Protein Bar — AgeGen

Oats, peanut butter and milk pressed into a bar and chilled — a made-at-home answer to a shop protein bar, with an ingredient list you can read.

Ingredients (1 serving)

  • Rolled oats — 50 g
  • Peanut butter — 30 g
  • Milk — 40 ml
  • Honey — 10 g

Macros per serving

  • Calories: 344 kcal
  • Protein: 16 g
  • Fat: 16 g
  • Carbs: 34 g
  • Fiber: 6 g

Key micronutrients

  • Magnesium — ~100 mg
  • Fiber — 6 g
  • Niacin — ~4 mg

Why it earns a spot in the rotation

  • Four ingredients, all of them recognisable — which is the practical difference from a shop bar rather than a nutritional one.
  • 6 g of fibre, where most commercial bars deliver it as isolated chicory root instead of as oats.
  • ~100 mg of magnesium, a mineral that is commonly short and rarely thought about at snack time.
  • No baking: it is pressed and chilled, so a batch takes minutes and keeps in the fridge.
