Instructions

• Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats, or use ungreased baking sheets.
• In a large bowl, combine 1 1/2 cups Nutella and 1/2 cup peanut butter and stir until smooth.
• Add 1 cup sugar and 2 eggs to the bowl and beat until fully incorporated and smooth.
• With the mixer on low, add 2 cups all-purpose flour a little at a time and mix just until no streaks of flour remain. Do not overmix.
• Portion the dough into 1-inch balls and place them on the prepared baking sheets about 2 inches apart.
• Press each ball flat with the bottom of a glass to form a cookie (about 1/4 inch thick), wiping the glass between presses if needed.
• Bake at 350°F for 7–8 minutes, until the edges are set. Remove from oven and let cookies cool on the baking sheet for a couple minutes, then transfer to a wire rack to cool completely.
• Once completely cool, assemble sandwiches by spreading frosting (1 batch) on the flat side of one cookie and topping with a second cookie; repeat with remaining cookies.
