01 - In a small saucepan over medium heat, melt 1/4 cup unsalted butter. Continue to cook, swirling occasionally, until the butter turns golden brown and develops a nutty aroma, 4 to 5 minutes. Remove from heat and let cool slightly.
02 - In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, and salt.
03 - In a separate bowl, whisk together the eggs, whole milk, cooled browned butter, and vanilla extract until fully combined.
04 - Pour the wet ingredients over the dry ingredients and stir gently until just combined. Fold in the crumbled bacon. Do not overmix; the batter should remain slightly lumpy.
05 - Preheat a nonstick skillet or griddle over medium heat and lightly grease with butter. Ladle about 1/3 cup pancake batter per pancake onto the skillet. Cook until bubbles form on the surface and the edges look set, about 2 to 3 minutes. Flip and cook until the second side is golden, 1 to 2 minutes. Repeat with remaining batter.
06 - In a small saucepan, melt the remaining 1/4 cup unsalted butter over medium heat until browned. Stir in the warmed maple syrup and keep warm over low heat.
07 - Stack pancakes on individual plates, layering with crispy bacon strips. Generously drizzle with brown butter maple syrup. Garnish with chopped pecans or fresh berries if desired and serve immediately.
