Ingredients
Scale
- 2 ½ cups all-purpose flour (312 g)
- 2 teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- ½ cup unsalted butter, softened (113 g)
- 1 ¾ cups granulated sugar (350 g)
- 3 large eggs, room temperature
- 1 cup buttermilk (240 ml)
- 2 teaspoons vanilla extract
- 1 ½ cups mint chocolate chips (270 g)
- ½ teaspoon peppermint extract
- 8 oz cream cheese, softened (227 g)
- ½ cup unsalted butter, softened (113 g)
- 3 cups powdered sugar (360 g)
- 1 teaspoon vanilla extract
- 2–3 tablespoons milk
- Green food coloring (a few drops) or natural spinach powder
- Fresh mint leaves (optional, for garnish)
Instructions
- Preheat oven to 350°F (175°C). Grease a 9×13 inch baking pan with butter or non-stick spray and lightly dust with flour.
- In a large bowl, whisk together flour, baking powder, baking soda, and salt.
- Using a mixer, beat softened butter and granulated sugar until light and fluffy, about 3-4 minutes.
- Beat in eggs one at a time, then stir in vanilla and peppermint extract until combined.
- Add dry ingredients in three parts, alternating with buttermilk in two parts, beginning and ending with dry ingredients. Mix gently after each addition.
- Fold in mint chocolate chips gently with a spatula.
- Pour batter into prepared pan and smooth the top evenly.
- Bake for 35-40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
- Remove cake from oven and cool completely on a cooling rack, about 45 minutes.
- Beat cream cheese and butter together until smooth. Gradually add powdered sugar, vanilla, and green food coloring, mixing until light and fluffy. Add milk as needed for spreadable consistency.
- Spread frosting evenly over cooled cake. Garnish with fresh mint leaves if desired. Chill for 15 minutes to set before slicing.
Notes
Use room temperature eggs and butter for best texture. Avoid over-mixing after adding flour to keep cake tender. Fold mint chocolate chips in gently to prevent melting. Chill frosting briefly if too soft. If frosting is too thick, add milk a teaspoon at a time; if too thin, add more powdered sugar.
