Cowboy Butter Swim Bread combines two favorites into one easy loaf. Inspired by my butter swim bread and packed with the bold flavors of cowboy butter, this savory bread is loaded with garlic, fresh herbs, Dijon mustard, and spices. Baked with melted cowboy butter for a tender crumb and buttery edges, it's perfect alongside dinner or served warm with extra cowboy butter for spreading.
In a medium bowl, mix the softened butter, Dijon mustard, chives, parsley, thyme, garlic, lemon juice, paprika, salt, pepper, cayenne, and red pepper flakes until fully combined.
Melt the cowboy butter and set aside. You will use ¼ cup for the pan, ¼ cup in the batter, and reserve the remaining butter for serving.
Bread
Preheat oven to 400°F. Spray a 9×5-inch loaf pan* with nonstick spray.
In a medium bowl, whisk together the flour, baking powder, sugar, and salt.
Pour in the buttermilk and stir until just combined. The batter will be thick and lumpy; do not overmix.
Pour ¼ cup of the melted cowboy butter into the prepared loaf pan, swirling to coat the bottom and sides.
Stir another ¼ cup of the melted cowboy butter into the batter until just combined.
Transfer the batter to the prepared pan and spread evenly.
Bake for 35 to 45 minutes, or until the top is golden brown and a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
Let the bread sit in the pan for 5 to 10 minutes before slicing so the butter absorbs.
Serve warm with the remaining cowboy butter on the side for spreading.
