Making the Cake

Preheat the Oven:

• Preheat your oven to 350°F (175°C). Prepare a 9-inch round cake pan by greasing and flouring them, or by lining them with parchment paper.

Prepare the Dry Ingredients:

• In a medium bowl, combine the flour, baking powder, baking soda, and salt by whisking them together. Set aside.

Cream the Butter and Sugars:

• In a large bowl, beat the softened butter with an electric mixer on medium speed until creamy and smooth. Gradually add the light brown sugar and granulated sugar, beating until the mixture is light and fluffy.

Add the Eggs:

• Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.

Combine Wet and Dry Ingredients:

• Add the dry ingredients to the butter mixture in three additions, alternating with the buttermilk. Begin and end with the dry ingredients. Mix the ingredients just until they are combined after each addition.

Bake the Cake:

• Divide the batter evenly between the prepared cake pans. Smooth the tops with a spatula. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean.

Cool the Cake:

• Allow the cake to cool in the pans for approximately 10 minutes. Then, remove the cake from the pan and transfer them to a wire rack to cool completely.

Making the Frosting

Melt the Butter:

• Melt the butter in a medium saucepan over medium heat, stirring occasionally.

Add Brown Sugar and Milk:

• Stir in the light brown sugar and milk. Stirring constantly, bring the mixture to a boil. Boil for 1-2 minutes, then remove from heat.

Cool the Mixture:

• Let the brown sugar mixture cool to room temperature.

Add Powdered Sugar and Vanilla:

• Gradually beat in the powdered sugar until the frosting is smooth and creamy. Stir in the vanilla extract.

Assembling the Cake

Frost the Cake:

• Place one cake layer on a serving plate. Spread a layer of frosting on top. Place the second cake layer on top of the first one and proceed to frost both the top and sides of the cake.

Serve and Enjoy:

• Slice the cake and serve. Enjoy your delicious Brown Sugar Cake with Brown Sugar Frosting!
