What is Carrot Cake?

Carrot cake is a sweet American cake which is made with carrots, spices and walnut pieces.  It’s commonly topped with cream cheese frosting and marzipan carrots.1

Popularized during the health craze of the late 20th century, carrot cake is regarded as a healthier alternative due to the use of vegetable oil instead of shortening and the addition of a recognized vegetable like carrots.1

Origin

Carrot cake is thought to have originated in England where housewives used sweet products (e.g carrots) to naturally sweeten their confections during World War II. In 1943, the Ministry of Food published a short recipe for carrot cake.1

Carrot cake’s popularity increased in the 1980s due to consumer’s perceived benefits of consuming vegetables with their highly caloric baked goods. Today, carrot cake is one of the most popular American desserts.

  2. Pre-heating oven: to 180 oC (350 oF) before preparing batter.
  3. Greasing:  a 13 x 9 inch pan is greased with shortening or butter and light flour sprinkle.
  4. Mixing: in a large mixing bowl mix oil, sugar and eggs at low speed.
  5. 2nd stage mixing: add flour, cinnamon, baking soda, vanilla and salt to the previous mixture and mix at low speed.
  6. Stirring: add shredded carrots and walnuts.
  7. Baking: baked at 180 oC (350 oF) for 40 – 45 minutes.
  8. Cooling

Production considerations

When making carrot cake some important considerations to take into account:5

  • Softening the carrots for smoother mouthfeel by increasing the baking soda content. The alkaline character of baking soda will soften carrots cell walls.
  • Toasted walnuts provide a characteristic and interesting flavor note to the cake.
  • For a thick and tangy cream cheese frosting, add buttermilk powder.

Regulations

Carrot cake doesn’t have a specific regulation, but all of its main ingredients are considered GRAS by the FDA when following good manufacturing practices.

In the EU, carrot cake is not as popular as in the US and thus doesn’t have any specific regulation. However, all of its core ingredients are considered safe by the EU regulating agencies.
