Step 1

Preheat oven to 350°F. Stir together flour, sugar, baking powder, salt, and baking soda in a large bowl. Whisk together buttermilk, eggs, and 1/2 teaspoon of the vanilla in a medium bowl. Gradually stir buttermilk mixture into flour mixture. Gently stir in 1/4 cup of the melted butter. (Do not overmix; batter will be lumpy.)

Step 2

Pour batter into a lightly greased (with cooking spray) 15- x 10-inch rimmed baking sheet. Bake in preheated oven 7 minutes; sprinkle evenly with strawberries. Continue baking until golden brown and a wooden pick inserted into thickest part comes out clean, 15 to 18 more minutes.

Step 3

While pancakes bake, stir together honey and remaining 6 tablespoons melted butter and 1/4 teaspoon vanilla in a small saucepan over medium-low; cook until warm, about 1 minute. Slice pancake into 16 squares, and serve with warm syrup.
