Ingredients

• 1 cup unsalted butter
• 1 cup chocolate chips
• 1.5 cups white sugar
• 4 large eggs
• 1 cup all-purpose flour
• 1 teaspoon vanilla extract

Instructions

1. 1 Preheat the oven to 325 degrees F (165 degrees C). Line 18 muffin cups with paper liners.
2. 2 Melt butter and chocolate chips in a saucepan over low heat, stirring until smooth, 3 to 5 minutes. Remove from the heat and let cool, 10 to 15 minutes.
3. 3 Beat sugar and eggs in a mixing bowl with an electric mixer until thoroughly combined. Mix in flour and vanilla. Fold in cooled chocolate mixture until smooth. Spoon batter into the prepared muffin cups, filling each 1/2 full.
4. 4 Bake in the preheated oven until a toothpick inserted into the center comes out clean or with a few moist crumbs, about 30 minutes.
