Ingredient Notes and Shopping Tips

  • Flour: Measure flour by spooning it into a measuring cup and leveling it off with a knife.
    • Do not dip your cup into the flour; you may accidentally overmeasure.
  • Baking Powder: Replace every 6-12 months even if still technically in date per the package. This will ensure they will rise as much as possible.
  • Milk: I always use whole milk for the moistest cake.
  • Canola Oil: You could also use vegetable oil here.
  • Crushed Oreos: I crushed mine in a plastic baggie with a rolling pin, so they still had a little texture to them. We don't want to be a fine power. You can also use a food processor if you have one.
  • Royal Blue Gel Food Coloring: This will give you a more vibrant color than liquid food dye.
  • Edible Eyes: If you can't find edible eyes, you can use another candy such as M&Ms or Skittles.

Use Unsalted Butter

I like to use unsalted butter so I can control the amount of salt in the recipe. Different brands of salted butter may have more or less salt than others.

For the Cupcakes

  1. Prep Work: Preheat oven and line pan with paper liners.
  2. Cream Butter: Combine butter and sugar. Add in eggs, oil ,and vanilla.
  3. Dry Ingredients: In a large bowl, whisk flour, salt, and baking powder together.  Alternate wet and dry ingredients until just combined.
  4. Fold in chocolate chips and crushed Oreos.
  5. Bake:  Fill liners and bake for about 21 minutes.

For the Frosting

  1. Cream butter, and add vanilla. Add powdered sugar a little at a time until just combined. Add heavy cream as needed.
  2. Add blue food coloring until you reach your desired shade.
  3. Pipe or spread onto cupcakes. Add edible eyes, and a cookie.

Tips

  1. Use room-temperature ingredients to help everything come together smoothly.
  2. Do Not Overmix: Mix until just combined. This is when the flour just disappears. Overmixing leads to a tough, dense cupcake.
  3. How To Tell When They're Done: Cupcakes are done when a toothpick inserted near the center comes out clean or with just a few crumbs. They will also spring back lightly when touched. Avoid overbaking, which can lead to a dry cake.

Fill Liners Only ¾ of the Way Full

The cupcakes will rise when baked.
