How to Make Heart Cake

Preheat your oven to 350°F (175°C). This step is crucial, as starting with a hot oven ensures your cake rises beautifully from the get-go.
Grease and flour a heart-shaped cake pan. This prevents the cake from sticking and makes for easy removal later—just a simple step for a perfect finish!
Mix together the flour, cocoa powder, and baking powder in a bowl. Stir well until combined—this blends the dry ingredients for an even flavor throughout your cake.
Beat the softened butter and sugar in another bowl until fluffy and pale. This usually takes about 3-5 minutes—your mixture should look light and airy!
Add the eggs one at a time, mixing well after each addition. This helps incorporate air into the batter, making it rise beautifully when baked.
Stir in the vanilla extract and milk until just combined. This liquid will keep your cake moist and add a wonderful flavor profile that complements the cocoa.
Gradually add the dry ingredients to the wet mixture, mixing gently. Be careful not to overmix; just combine until you don’t see any dry flour—the batter should be smooth and slightly thick.
Pour the batter into the prepared pan, smoothing out the top with a spatula. This will help it bake evenly and look lovely when it’s time to serve!
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The edges will start to pull away from the pan—an excellent sign that it’s ready!
Let it cool in the pan for about 10 minutes before carefully removing it. This cooling period allows the cake to set and makes it easier to transfer without breaking.

Optional: Serve with a dusting of powdered sugar or a dollop of whipped cream for an extra touch of love.

Make Ahead Options

These Heart Cake preparations are perfect for busy home cooks looking to save time during the week! You can prep the dry ingredients (flour, cocoa powder, and baking powder) and store them in an airtight container up to 3 days in advance. Additionally, you can cream the butter and sugar ahead of time and refrigerate it for up to 24 hours; just bring it back to room temperature before mixing in the eggs and remaining wet ingredients. This ensures your cake remains just as delicious when baked. When you’re ready to serve, simply follow the final steps—mix the wet ingredients with the dry and bake your delightful cake, bringing love into every irresistible slice without the last-minute rush!
