How to Make It
In a large bowl, whisk together the buckwheat flour, all purpose flour, baking powder, baking soda, sugar, and salt. In a separate, small bowl, whisk together the egg, buttermilk, beer, and butter. Stir the egg mixture into the flour mixture until smooth (try not to overmix).
Heat a large nonstick skillet or griddle over medium heat and lightly grease with melted butter. For each blini, spoon a heaping tablespoon of batter onto the skillet. Cook until lightly browned and bubbles show on the surface, about 2 minutes, then flip and cook another minute. Transfer cooked blini to plate and place in a 200 degree oven to keep warm. Repeat, buttering the skillet between batches, until batter is gone. (If batter thickens up, thin with remaining buttermilk.)
In a small bowl, stir together the cream cheese and blue cheese until combined. Serve the blinis topped with the cheese mixture, seasoned with salt and pepper, and drizzled with honey.
