Step-by-Step Instructions
- Preheat the oven.
Set it to 350°F (175°C). Line a muffin tin with liners or lightly grease it. - Prep the oats.
Pulse oats briefly in a blender if you want softer muffins. - Mix dry ingredients.
Combine oats, flour, baking powder, baking soda, and salt in a bowl. - Mix wet ingredients.
Whisk eggs, yogurt, milk, sweetener, and vanilla in another bowl. - Combine gently.
Add dry ingredients to wet and mix until just combined. - Fold in blueberries.
Gently. Blueberry explosions are not the goal. - Fill muffin cups.
About ¾ full. Don’t overdo it. - Bake.
Bake for 18–22 minutes, until a toothpick comes out clean. - Cool slightly.
Let them rest before removing. Muffins need a minute to chill.
Common Mistakes to Avoid
- Overmixing the batter.
Leads to dense muffins. Stir gently and stop early. - Using too much sweetener.
Blueberries already help—don’t overpower them. - Skipping liners without greasing.
Muffin surgery is not fun. - Adding frozen blueberries straight from the freezer.
Toss them in flour first to prevent bleeding. - Overbaking.
Dry muffins = sadness. Watch the oven.
