Ingredients & Equipment Used In This Recipe
While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients (and equipment) needed for this recipe have been listed below and linked to Amazon or other stores if available online.
It does not include staple ingredients such as oil, salt, and pepper, as you’re likely to have those in your kitchen already. The complete list of ingredients with measurements is found in the recipe card.
- Funfetti Cake Mix – you will need 2 boxes of the cake mix, plus eggs and butter.

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. Please note, you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).
