Green Monster Muffins for Picky Eaters

Monster Muffins, also known as Spinach Muffins or Green Muffins, are a creative way to sneak some greens into your child’s diet. These Halloween muffins are not only visually appealing with their vibrant green color but also packed with nutrients.

Many parents struggle with picky eaters, especially when it comes to getting their kids to eat their vegetables. Monster Muffins are the perfect solution to this age-old problem. The spinach used in these muffins has no taste but is rich in vitamins and minerals, like calcium, potassium, and vitamin C. This means your child won’t even realize they’re eating veggies.

 What You’ll Need

  • Muffins: The muffin is a basic muffin batter of milk, eggs, flour, brown sugar, baking soda, and salt. The green color comes from spinach and avocado.
  • Chocolate chips: You can use whatever type of chocolate chips that you like. I prefer semi sweet chocolate chips, but milk chocolate or dark chocolate can also be used.
  • Edible googly eyes: This gives that fun monster look.

How to Make Monster Muffins

Make the Batter: In a large mixing bowl, combine the dry ingredients. Blend the spinach, milk, egg, avocado, and butter in a food processor or blender until well combined. Add it to the dry ingredients and mix well. Fold in the chocolate chips.

Make the Muffins: Add 1/4 cup of batter to the cupcake liners in a muffin tin. Sprinkle with more chocolate chips and add googly eyes. Bake for 18 minutes or until the tops are not soft.

Can You Leave Homemade Muffins Out Overnight?

Yes muffins can be left out overnight. These muffins do not need to be stored in the refrigerator. The muffins can be moved to an airtight container or even left in the muffin pan and wrapped well with plastic wrap. Save them for an easy breakfast or a simple snack.

Tips and Tricks For Monster Muffins

Here are some tips and tricks to help you make the best spinach muffins, whether you’re aiming for a Halloween-themed treat or just looking to get some greens into your diet:

  • Use Fresh Spinach: Fresh spinach leaves work best for achieving that vibrant green color and fresh flavor. Avoid using frozen spinach as it can add excess moisture to the batter.
  • Blend Thoroughly: When blending the spinach with other wet ingredients, ensure that you blend them thoroughly until you have a smooth, uniform mixture. This will prevent any green bits from showing up in your muffins.
  • Whole Wheat Flour: Whole wheat flour is a healthier option than all-purpose flour. It adds fiber and nutrients to your muffins. If you prefer a lighter texture, you can use a combination of whole wheat and all-purpose flour.
  • Proper Mixing: When combining the wet and dry ingredients, be careful not to overmix. Overmixing can result in denser muffins. Mix until the ingredients are just combined.
  • Storage: Store your Monster Muffins in an airtight container at room temperature for a day or two. For longer storage, freeze them individually, wrapped in plastic wrap and placed in a freezer-safe container or bag.
  • Need to Make it Gluten Free: Use a one to one gluten-free flour that you like in this recipe to make it gluten free.

This recipe can also be made with almond milk instead of cow’s milk.

By following these tips and tricks, you’ll be well on your way to making delicious and nutritious Monster Muffins that both kids and adults will enjoy.
