Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

all‑purpose flour
sugar
baking powder
salt
eggs
milk
vegetable oil or melted butter
vanilla extract
red food coloring (for the heart)
cocoa powder (optional, for the outer cake)
optional toppings (powdered sugar, frosting)

Directions

Preheat your oven to about 175 °C (350 °F). Grease and flour two loaf pans or round cake pans.
In a mixing bowl, whisk together flour, sugar, baking powder, and salt.
In a separate bowl, whisk eggs, milk, oil or melted butter, and vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients and stir until just combined.
Divide the batter if making two colors — reserve a portion for the heart batter and add red food coloring to it, stirring until the desired shade is reached.
Pour the colored batter into one pan and bake until set (about 20 minutes). Once cooled, use a heart‑shaped cookie cutter to cut out hearts from this colored cake.
Place the heart shapes upright in a greased pan. Carefully pour the plain batter around and behind the hearts so they stay centered. If desired, you can add a chocolate batter instead of plain for contrast.
Bake the full cake for about 40–50 minutes, until a toothpick inserted into the cake (but not the hidden hearts) comes out clean.
Cool completely before slicing so the heart shapes hold their form. Add powdered sugar or frosting if desired.

FAQs

How do the heart shapes stay intact?

The baked colored cake is cut into hearts and placed upright in the batter before baking so the shape remains visible when sliced.

What cake flavors work best?

Vanilla, chocolate, or strawberry are popular choices, but any basic cake works well.

Can I make this without food coloring?

Yes — use naturally colored ingredients like beet juice or fruit purees.

Do I need special pans?

No — loaf pans or round cake pans both work for making the heart shapes.

Can I make this gluten‑free?

Yes — substitute a gluten‑free flour blend.

How far in advance can I bake it?

Bake a day ahead and decorate just before serving.

Can I use boxed cake mix?

Absolutely — box mixes work great and save time.

Why isn’t my heart shape showing clearly?

Make sure the heart cake is tall enough and the outer batter covers it evenly without tilting.

Can I make mini hidden shape cakes?

Yes — use cupcake liners and small cutters for individual portions.

Should I frost this cake?

Frosting is optional — powdered sugar or a simple glaze is lovely too.

Instructions

Preheat oven to 350°F (175°C). Grease and flour two loaf pans.
In a large bowl, whisk together flour, sugar, baking powder, and salt.
In another bowl, whisk eggs, milk, oil (or melted butter), and vanilla extract until smooth.
Combine wet and dry ingredients, mixing until just combined.
Divide batter into two portions. Add red food coloring to one portion and mix until evenly colored.
Pour the red batter into one prepared pan and bake for 20–25 minutes, or until a toothpick comes out clean. Let cool completely.
Use a heart-shaped cookie cutter to cut out hearts from the red cake. Set aside.
To the remaining batter, optionally mix in cocoa powder for a chocolate outer cake.
In a clean greased loaf pan, pour a thin layer of plain/chocolate batter. Stand heart cut-outs upright in a row through the center.
Carefully pour remaining batter around and over the hearts to fully cover.
Bake for 40–50 minutes, or until a toothpick inserted into the outer cake comes out clean.
Cool completely before slicing. Top with powdered sugar or frosting if desired.

Notes

Use a heart-shaped cookie cutter that matches the loaf height for a clean shape.
Be sure to keep heart cut-outs aligned and upright during assembly.
For clean slices, use a sharp knife and wipe between cuts.
Try other shapes like stars or letters for different themes.
Boxed cake mix can be used for ease.
