Mix the flour, sugar, salt, baking powder, and cinnamon in a large bowl.
Mix the egg, milk, melted butter, and vanilla in a separate bowl. (Ensure the butter is chilled before adding, or mix the egg and milk before adding the butter to ensure the heat of the butter doesn’t cook the egg.)
Add the wet ingredients to the dry and mix until just combined, leaving some lumps in the batter. Let sit for 5 minutes.
Scoop the batter, 1/3 c at a time, onto a greased griddle at medium heat. Cook for approximately 90 seconds to 2 minutes, until small bubbles form around the edges, then flip. Cook 1 additional minute and remove from heat.
Serve with lemon whipped cream and fresh fruit, or your favorite toppings.
Lemon Whipped Cream
Pour the whipping cream in the bowl of a stand mixer, and whisk on medium speed until it begins to thicken. Add lemon juice and sugar a little bit at a time.
Continue to beat until soft peaks form, then turn off mixer.
