Plant Cupcakes for Earth Day

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions and ensure that you have all the ingredients and equipment required and understand the steps and timings involved.

Earth Day is an annual event on April 22 to demonstrate support for environmental protection. First held on April 22, 1970, it now includes a wide range of events coordinated globally by including 1 billion people in more than 193 countries. The theme for 2022 is Invest in Our Planet.


Earth Day is a great time to discuss environmental issues with your children, like deforestation, pollution, and climate change. Talk about ways you can help – maybe picking up litter in your neighborhood, planting a tree, recycling at home, or simply going for a walk in nature.

In honor of Earth Day, we’re going to show you how to make plant cupcakes that use crushed chocolate cake as “soil.” It’s a fun way to teach kids about how our food grows (just make sure they understand that cupcakes don’t come from plants!!)

Not only will these look adorable and taste delicious, but they are also really easy to make – you just need a batch of chocolate cupcakes (from a box mix, or even ready-made), a can of chocolate frosting, and some mint sprigs!

Ingredients & Equipment Used In This Recipe

For your convenience, any specialized or notable ingredients and equipment needed to make these cupcakes have been listed below and linked to Amazon or other stores if available online. Standard ingredients such as flour or sugar are not listed, as you are likely to have those in your kitchen. The full list with measurements is found in the recipe card.

Cupcakes & Decorating Ingredients

Cupcake Decorating Equipment

  • Large Piping Bagyou can use disposable or reuseable, your choice.
  • Large Round Piping Tip – for example, Wilton 1A, optional, you can snip the end off the disposable piping bag instead.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog! I try to give American, imperial, and metric measurements in my recipes. You can mix cup measurements with weighted measurements, but never imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).

Plant Cupcakes Recipe Tips

Cupcake Making Tips

  • These cupcakes are made using a box of cake mix, but you can prepare your favorite cupcake recipe if you prefer.
  • Use your choice of cupcake liners – themed to the cupcakes, plain white or black, or a complimentary color.
  • Use an ice cream scoop to equally divide the cupcake mixture between the cupcake liners. Fill them about three-quarters full.
  • The cupcakes should be ready in about 20 minutes – test their doneness by inserting a toothpick into the cakes. It should come out clean when the cupcakes are cooked all the way through. Bake for an extra 2 minutes and check again.
  • Cool the cupcakes in the pan for 5 minutes before transferring them to a wire rack to cool completely before frosting.
  • Use a piping bag with a large round piping tip attached, or with the end snipped off if you don’t have piping tips.
