Notes

Disclaimer: I bake by weight for accuracy. Cup measurements are approximate and may vary depending on how you scoop.
Audrey’s Tip: For the best flavor, use a mix of tart and sweet apples—like Granny Smith and Honeycrisp—so you get a balance of bright flavor and natural sweetness in every bite. Also, dice the apples small so they soften evenly and don’t weigh down the muffins.
