Step 1: Preheat and prep
Set your oven rack in the center of the oven. Preheat the oven to 425°F (218°C). Line up your muffin pan and get everything ready before you start mixing.
That high heat matters. It helps the muffins rise fast at the start, which gives them those bakery-style tops. Why settle for squat muffins when you can get a nice dome?
Step 2: Mix the dry ingredients
In a large bowl, whisk together:
all-purpose flour
oat flour
baking powder
baking soda
sea salt
Whisking helps break up clumps and spreads the leavening evenly through the batter. You want each muffin to rise the same way, not act like it missed the memo.
Step 3: Mix the wet ingredients
Melt the vegan butter in a mug or small bowl. If the non-dairy milk feels cold, warm it just a little in the microwave so it loses the chill.
In a medium bowl, combine:
non-dairy milk
lemon juice
apple cider vinegar
vanilla extract
sugar
Whisk well, then pour in the melted vegan butter and whisk again. The mixture will look a little odd for a second, and that is fine. Baking likes drama, apparently.
Step 4: Combine wet and dry
Pour the wet ingredients into the dry ingredients. Stir until just combined. Do not overmix.
The batter should look thick and fluffy. That texture tells you you’re on the right track. If you stir too much, the muffins can turn tough, and nobody invites tough muffins to brunch.
Step 5: Fold in the blueberries
Gently fold in the blueberries with a spatula. Try not to crush them unless you want blue streaks throughout the batter.
If you use fresh berries, they usually hold their shape nicely. If you use thawed frozen berries, they may tint the batter a little more, but the muffins will still taste great.
Step 6: Fill the muffin pan
Fill each muffin cup almost all the way to the top. A measuring cup helps you scoop the batter evenly. If you want that bakery look, press 2 or 3 extra blueberries into the tops.
Sprinkle a little sugar over each muffin top. That tiny extra step gives you a sweet crunch after baking, and it looks pretty too. Because yes, we do eat with our eyes first.
Step 7: Bake with a temperature drop
Put the muffins in the oven, then immediately reduce the temperature to 375°F (190°C).
Bake:
24 to 26 minutes for jumbo muffins
21 to 23 minutes for standard muffins
Check doneness with a toothpick. It should come out clean or with just a few moist crumbs. Let the muffins do their thing without opening the oven too early unless you enjoy deflating your own hard work.
Step 8: Cool properly
Let the muffins cool in the pan for 10 minutes. Then move them to a cooling rack.
Jumbo muffins feel delicate while they stay hot, so I like to place them top-side-down on the cooling rack. That little move helps them cool evenly without getting soggy bottoms. And yes, soggy bottoms deserve no mercy.
