How to make marble red velvet bundt cake step by step

Step 1 - preparing dry ingredients

• In a large bowl, add flour, sugar, and baking powder - mix with a spoon.
  200 g wheat flour - all-purpose, 200 g sugar, 1 teaspoon baking powder
  

Step 2 - preparing wet ingredients

• Mix together eggs, milk, oil, and vanilla extract.
  3 eggs , 60 ml milk, 3 tablespoons oil, vanilla extract
  

Step 3 - preparing the bundt cake

• Add butter in pieces to the dry ingredients and lightly mix everything together, or knead into a crumbly dough.
  200 g butter
  
• Pour in the wet ingredients and briefly mix the batter until it is relatively smooth.
  
• Set aside about 1/3 of the batter - for me, it was about 4-5 tablespoons of batter.
  
• To the reserved portion of the batter (smaller one), add cocoa and food coloring - mix with a spoon.
  1 teaspoon unsweetened cocoa powder, approx. 0.5 teaspoon red food coloring
  

Step 4 - adding batter to the baking pan

• Spread a portion of the white batter onto the bottom of the prepared pan (for me, lined with baking paper).
  
• Dollop some red batter in "mounds".
  
• Add more white batter and some red batter until both are used up.
• Gently level the surface of the batter.
• With a sharp knife or a skewer, gently swirl the batters in the pan.
  

Step 5 - baking the red velvet bundt cake

• Place the pan with the batter into an oven preheated to 180 degrees Celsius (top/bottom heat mode) and bake for about 45-50 minutes - until a skewer inserted comes out clean.
• After baking, let the cake cool, and before serving, dust with powdered sugar.
