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.
    food coloring
  • 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.

Rainbow bundt cake – notes

I prepared this rainbow bundt cake for a special occasion for me. It’s been 9 years since I started creating this blog! Time flies so fast that these 9 years passed in a blink. I myself was surprised recently that so much time has passed. My children have grown up and are now trying their hand in the kitchen, and the blog, as my third child, has developed quite well. Year after year, you visit me more often, bake and cook, leave comments.

Thank you very much for that! It’s great to know that my work has such a large audience. I hope you’ll stay with me for the coming years, because I’m not planning to leave you!

And now a little about this amazing colorful bundt cake :) The rainbow bundt cake turned out very fluffy and delicate. Perfectly buttery and not too sweet. I chose rainbow colors because a rainbow always reminds me of something very positive and always brings a smile to my face. You can, of course, use other colors – whatever you have available at home.

How to make a bundt cake with a rainbow inside – tips

The base of this bundt cake is a light and fluffy creamed buttery dough. For the cake to be super soft, fluffy, and light after baking, you need to cream the butter and sugar very well. To do this, mix soft butter with sugar (I recommend powdered sugar) on high speed for several minutes – up to 10 minutes. Sift the flour through a sieve – this ensures better aeration and additionally contributes to the fluffiness of the cake. And finally – egg whites, or more precisely, whipped egg whites – at the end, add the whipped egg whites to the batter and gently mix. I used only egg whites here because I wanted to get nice colors – so if you happen to have unused egg whites, make such a bundt cake with just egg whites. You can also use whole eggs – in that case, take 3 large ones.

Remember one more basic thing with creamed cakes – only cream the butter and sugar for a long time! Then, after adding the flour, mix the batter briefly and on low speed. Mixing the batter with flour for too long can cause the cake to lose its fluffiness and become tough! For coloring the batter, I used food colorings in gel and powder (yellow and purple colors) and both types worked excellently!
