Preheat your oven to 350°F (175°C). Ensure it’s fully heated before you place your cake inside.

Prepare the heart-shaped pan by greasing it with butter or non-stick spray. Lightly dust with flour to help the cake release easily once baked. For a smoother finish, you can also line the bottom of the pan with parchment paper.

Sift dry ingredients: In a large bowl, sift together flour, baking powder, and salt. This will ensure that your batter is smooth and free of lumps.

Cream butter and sugar: In a separate bowl, beat together softened butter and sugar using an electric mixer or stand mixer. Mix until light and fluffy, about 3-4 minutes.

Add eggs and vanilla: Add eggs one at a time, mixing well after each addition. Then, stir in the vanilla extract for a warm, aromatic flavor.

Combine with dry ingredients: Gradually add the dry ingredients to the butter mixture, alternating with the milk. Mix until just combined overmixing can make your cake dense.

Pour and smooth: Pour the batter into the prepared heart-shaped pan. Use a spatula to spread it out evenly.

Bake: Place the pan in the oven and bake for 25-30 minutes. Check for doneness by inserting a toothpick into the center of the cake it should come out clean when the cake is done.

Cool the cake: Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. This prevents the cake from becoming soggy or breaking.

Beat the butter: In a large mixing bowl, beat softened butter until smooth.

Add powdered sugar: Gradually add powdered sugar, one cup at a time, and beat until fluffy and light.

Mix in vanilla: Stir in vanilla extract, and then add a tablespoon or two of milk to reach your desired frosting consistency. It should be smooth, spreadable, and not too thick or runny.

Optional color: If you want a colorful frosting, add a few drops of food coloring and mix until you achieve the desired shade.

Level the cake: If the top of your cake has domed, use a serrated knife to level it off, ensuring a smooth and even surface for frosting.

Apply a crumb coat: Spread a thin layer of frosting over the entire cake to seal in any crumbs. This is your crumb coat, and it ensures the final layer of frosting will be smooth.

Chill: Refrigerate the cake for 15-20 minutes to set the crumb coat.

Add the final layer of frosting: Once chilled, apply the remaining frosting generously over the cake. Use a spatula for a smooth finish or pipe swirls, rosettes, or borders for extra flair.

Decorate with flair: This is where you can get creative! Use edible glitter, sprinkles, or fondant to add sparkle and elegance. Fresh fruit like strawberries or raspberries can bring a pop of color, while edible flowers can add a natural touch.

Fill with a surprise: For an extra layer of flavor, consider filling your cake with chocolate ganache, jam, or whipped cream before frosting. This creates a delightful surprise when you slice into it.
