Turn your oven to 375°F and place a 12-cup muffin tin inside to heat up.
02 -
Throw all the batter ingredients in a blender and blend for half a minute until it's smooth and fluffy. Or, whisk everything together in a bowl for 2-3 minutes instead.
03 -
Take the preheated muffin tin out and use a brush to spread melted butter into each cup.
04 -
Divide the batter evenly among the muffin cups, filling each about three-quarters full.
05 -
Drop 2-3 diced strawberries and 2-3 blueberries onto the top of each cup of batter.
06 -
Bake them until golden and puffed, which should take about 30-35 minutes.
07 -
Leave the muffins to cool in the tin before popping them out. It's normal if they deflate when cooling. Dust with icing sugar or pour maple syrup on top if you'd like.
