It’s not just about flavor, but about achieving a tender crumb that melts in your mouth.

Ingredient Insights for Better Muffins
- Peanut Butter: Natural, oozing with flavor, adds moistness. Swap with almond or cashew butter for nutty variations.
- Flour: All-purpose gives structure, but whole wheat adds a hearty touch. Slightly denser, more wholesome.
- Sugar: Regular white sugar keeps it classic, but honey or maple syrup can add a richer sweetness.
- Eggs: Bind ingredients and lift the batter. Flax eggs work if you want vegan options, but keep in mind they’re less fluffy.
- Milk: Keeps batter moist. Almond or oat milk are good dairy-free options, with a slightly different flavor.
