Add the flour, granulated sugar, baking powder, baking soda, kosher salt, and poppyseeds into a large bowl. Mix with a whisk until the ingredients are evenly combined.
Add in the buttermilk, lemon zest, lemon juice, egg, vegetable oil, and vanilla extract. Mix until everything is well combined.
Heat a pan over medium heat. Add in a pad of butter to coat the bottom of the pan. Once it has melted, pour in the pancake batter. Use a ¼ cup scoop to make 10 small pancakes or a ½ cup scoop to make 5 larger pancakes. Cook the pancakes for about 2 minutes on each side until golden brown and cooked through. Continue to cook the pancakes in batches.
Top the pancakes with a pad of the lemon honey butter and fresh fruit. Serve with maple syrup and enjoy!
