Easter Monster Cookies: Chewy, Gooey & Festive!
Ingredients
- 1 cup (2 sticks) unsalted butter, room temperature
- 1 cup (258 g) creamy peanut butter
- 1 ½ cups (300 g) light brown sugar, packed
- 2 large eggs, room temperature
- 2 cups (250 g) all-purpose flour
- 1 cup (90 g) old fashioned oats
- 1 teaspoon baking soda
- ½ teaspoon kosher salt
- 1 cup (203 g) Easter M&M’s milk chocolate candies, pastel blend
- 1 cup Easter peanut butter M&M’s eggs, roughly chopped
Instructions
- Line baking sheets with parchment paper. Set aside.
- In the bowl of a stand mixer with a paddle attachment (or using a handheld mixer), beat the butter on medium-high speed until smooth (about 1 minute).
- Add peanut butter. Beat for about 2 minutes, or until smooth.
- Add brown sugar. Cream together on medium-high speed for 2 minutes, until smooth.
- Add eggs, one at a time, mixing for 30 seconds after each addition. Scrape down the sides of the bowl and mix again if needed.
- With the mixer off, add flour, oats, baking soda, and salt. Mix on low until just combined, being careful not to overmix.
- With the mixer off, add Easter M&M’s and peanut butter M&M’s eggs. Mix on low speed until just incorporated.
Notes
Pro tips
- Don’t overmix the dry ingredients: Overmixing develops gluten, leading to tougher cookies instead of soft and chewy ones. Mix until just combined.
- Use room temperature ingredients: Butter and eggs at room temperature cream together more smoothly, creating a uniform batter and better cookie texture.
- For perfect doneness: Bake until the edges are set and lightly golden, but the centers still look slightly soft. They will continue to set as they cool.
- Storage: Store baked monster cookies in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months. Thaw at room temperature or warm gently in the microwave.
These Easter Monster Cookies are a joyous addition to any spring celebration. Enjoy the perfect blend of sweet, salty, and chewy textures. Happy baking!
