Blueberry Oat Muffins: Ingredients & Substitutions

  • All-purpose flour. To make them gluten-free, use a 1:1 gluten-free flour blend. You can also replace up to half the flour with whole wheat pastry flour.
  • Whole milk. Half-and-half or 2% milk work well as substitutes.
  • Sour cream. Full-fat Greek yogurt or plain yogurt are good alternatives; vanilla-flavored yogurt can be used for extra sweetness.
  • Salted butter. Unsalted butter, coconut oil, canola oil, or ghee are fine substitutes.
  • Old-fashioned oats. Quick-cooking oats work in a pinch.
  • Maple syrup. Honey is a great swap.
  • Blueberries. Fresh blueberries give the best texture and flavor. If using frozen, thaw them in a colander to drain excess liquid before adding to the batter.

Bake & Cool

Note: Baking the muffins across two tins helps them rise higher. Grease two standard muffin pans and plan to bake 7 muffins in each pan. The recipe yields 14 muffins total.

Scoop about 1/4 cup of batter into each well, spacing them so there are seven per tin. Bake at 375°F (190°C) for 17–19 minutes, or until the tops spring back when lightly touched and a toothpick inserted into the center comes out clean.

Let the muffins cool in the pans for about 20 minutes, then run a spoon or sharp knife around the edges to remove them. Transfer to a wire rack to cool completely.

Recipe FAQs

Why coat blueberries in flour before baking?

Coating berries in flour helps prevent them from sinking to the bottom of baked goods. This is most helpful when using frozen, thawed blueberries.

Can I use frozen blueberries?

Yes. Thaw them in a colander and drain excess liquid. Tossing thawed frozen blueberries in a little flour helps absorb extra moisture and prevents sinking.

Should I chop blueberries for muffins?

No—leave blueberries whole to keep the best texture and flavor.
