Gluten-Free Zucchini Muffins

Gluten-Free Zucchini Muffins make the best of summer’s zucchini! Tender oat flour bakes into perfectly moist and delicious muffins that are perfect with a morning cup of coffee.

Gluten-Free Zucchini Muffins

A muffin with a cup of tea — or coffee — hits the spot on a foggy morning like the ones we’ve been having here. A slight precursor to fall? Or just the typical Northern California summer weather? Either way, it makes my plants happy not to have the sun baking down on them all day and it makes things feel very cozy to be wrapped in a quiet blanket of gray mist until late morning, so I’ll take it. Along with a gluten-free zucchini muffin, please.

There’s no way around it — I love these muffins. The recipe needs just a half cup of maple syrup to sweeten the batch, and each muffin turns out plenty sweet. A combination of oat and almond flours balance each other perfectly so the muffin is slightly hearty yet very tender. Toasted walnuts add crunch and the shredded zucchini plus the almond flour adds moisture.

Substitution Suggestions

  • Oat Flour – Try sorghum flour.
  • Almond flour – Try teff flour or tiger nut flour.
  • Maple syrup – Swap honey or cane sugar.

These muffins are easy to make dairy free. Add 3 teaspoons vinegar to 2/3 cup coconut milk and let stand for 10 minutes, then use in place of the buttermilk in the recipe.
