How to Make Marble cake(Neopolitan single-layer cake)
Step 1: Prepare Your Ingredients
Have all the ingredients, utensils, and appliances ready. Allow the refrigerated ingredients to reach room temperature for best results.
Step 2: Prepare the Cake Pan
Lightly butter and line the bottom of a 9″ round cake pan. Set aside while you prepare the batter.
Step 3: Mix Dry Ingredients
Sift together flour, baking powder, baking soda, and salt into a large bowl. Set aside as you prepare the wet ingredients.
Step 4: Cream Butter and Sugar
Add softened butter to a large bowl. Use your mixer to beat on high speed until smooth. Then add granulated sugar and vanilla extract; beat until light and fluffy.
Step 5: Add Eggs
Add one egg at a time to the creamed mixture. Combine gently without over-mixing. Scrape down the bowl frequently during this process.
Step 6: Incorporate Flour and Milk
Alternately add dry ingredients and milk into the batter starting with flour. If using a hand mixer, maintain low speed; if using a spatula or whisk, use folding movements.
Step 7: Prepare Colored Batters
In three separate bowls, divide the batter accordingly. One bowl stays plain, one gets pink food coloring until bright pink is achieved, and cocoa mixture is added to another bowl until light chocolate color forms.
Step 8: Preheat Oven
Preheat your oven to 160C (320F).
Step 9: Layer Batters in Cake Pan
Add spoonfuls of each colored batter alternatively into the prepared pan. Use a knife or skewer to swirl them gently for that classic marble effect.
Step 10: Bake
Transfer the pan into the oven and bake for about 50 minutes. Check doneness by inserting a skewer at around the 40-minute mark; it should come out clean when done.
Step 11: Cool Cake
Once baked, let it cool in the pan for about 15-30 minutes before transferring it onto a cooling rack until completely cool.
Step 12: Make Butter Icing
In another bowl, beat softened butter until light. Sift icing sugar over it while mixing; add milk gradually until smooth frosting forms. Add small drops of pink coloring for aesthetics without fully mixing it in.
Step 13: Frost Cake
Spread frosting evenly over the top of your cooled marble cake. Chill for about 10 minutes before serving so that icing sets slightly.
