In a big bowl, mix together the flour, sugar, baking powder, baking soda, salt, egg, melted butter, vanilla extract, and buttermilk until it’s thick but still a bit clumpy. Don’t mix too much!
Heat up a griddle or a big pan on medium-low to medium heat.
Butter the griddle or pan so your pancakes don’t stick.
Take a skewer or fork and dip each strawberry slice into the pancake batter, then put it on the griddle or pan. Keep doing this until your pan is full.
Cook each mini pancake until it’s golden on one side, then flip it and cook the other side.
Once you’ve made all your pancakes, serve them up with some maple syrup and powdered sugar.
