How to make rainbow bundt cake step by step

• Grease the bundt cake pan with butter and sprinkle with breadcrumbs.
• Cream the butter with sugar until a white and fluffy mass is formed - I like to use powdered sugar here - then the mixture comes together faster - I usually mix for a few minutes.
  200 g butter, 200 g sugar
• Sift the flour with baking powder through a sieve.
  350 g wheat flour - all-purpose, 2 teaspoons baking powder
• Add the flour to the butter mixture alternately with buttermilk - mix briefly - just until combined.
  240 ml buttermilk
• Whisk the egg whites until stiff and add to the batter - gently mix.
  4 egg whites
• Prepare 5 smaller bowls - set aside 4-5 tablespoons of batter in one. 3 tablespoons in the second, and 2 tablespoons in each of the remaining bowls.
• Color the bowl with the most batter red, the next one yellow, then green, blue, and purple.

• Transfer approximately 2/3 of the remaining batter to the pan.
• Spread the red color in the center and distribute it evenly.
• Layer yellow on top of red - so that the edges of the red are visible.
• Layer green on top of yellow, then blue, and finally purple.
• Layer the rest of the white batter on top of the colored batter.
• Bake at 170 degrees Celsius (fan-assisted mode) for about 45 minutes - until a dry skewer comes out clean.
• After baking, carefully remove the bundt cake from the pan and let it cool.
• Prepare the glaze - add milk spoon by spoon to the powdered sugar and mix - do not make the glaze too runny, or it will all drip off the bundt cake.
  100 g powdered sugar, 2-3 tablespoons milk
• Finally, you can sprinkle the cake with colorful sprinkles.
