Preheat oven to 375 degrees. Line a 12 cup muffin pan with liners or grease with cooking spray/butter.
In a large bowl, combine the 1 ¼ cups flour, ½ cup cornmeal, ½ cup brown sugar, ½ teaspoon salt and 1 tablespoon baking powder.
In a small bowl, combine the 1 cup milk, ½ cup butter, 2 Tablespoons honey and 1 egg.
Add the wet ingredients to the dry ingredients and stir until just combined. Gently fold in the 1 ½ cups blackberries.
Spoon batter into prepared muffin tins.
Bake in preheated oven for 20-25 minutes. Allow to cool 5-10 minutes and then remove from the pan. Serve warm with the whipped honey butter (recipe below).
Whipped Honey Butter
To make the butter, whip together the softened 1 stick butter and 1 Tablespoon honey until light and creamy, 3-5 minutes.
Notes
To store leftover muffins, place them in a plastic bag or airtight container lined with a paper towel (this prevents them from getting soggy). Seal and store at room temperature for up to 4 days.
