Delicious Frosted Chocolate Chip Cookie Bar Recipe easily made in the slow cooker then topped with a rich and creamy buttercream frosting…

Actually using your slow cooker to make cookie bars is a really great idea.
These bars are super easy to make, you just mix up the cookie dough batter, spoon it into your foil-lined slow cooker bowl and walk away. They’re done in a little over 2 hours.


These cookie bars are buttery and chewy. They’re full of chocolate chunks and will disappear if they are left unattended – that’s a promise!
I made a simple buttercream frosting to spread over the top. An easy recipe and so delicious too.
Enjoy!
Slow Cooker Frosted Chocolate Chip Cookie Bars

Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1/2 teaspoon cinnamon
- 1 cup butter, softened (2 sticks)
- 3/4 cup granulated sugar
- 3/4 cup packed brown sugar
- 1 teaspoon vanilla extract
- 2 large eggs
- 2 cups semi-sweet chocolate chips
FROSTING
- 1/2 cup butter, softened
- 1 1/2 cup powdered sugar, sifted
- 1/8 teaspoon salt
- 1 teaspoon vanilla extract
- 2 tablespoons heavy cream
- Sprinkles (optional)
Instructions
- Combine flour, baking soda, salt and cinnamon in a small bowl.
- Beat butter in a large mixing bowl for 30 seconds. Add the granulated sugar and the brown sugar to the bowl and mix well.
- Add the eggs, one at a time, beating well after each addition. Mix in the vanilla.
- Gradually beat in the flour mixture.
- Stir in the chocolate chips.
- Line the bowl of the 7-quart slow cooker with aluminum foil (this will make the bars easier to get out). Spread a little melted butter over the foil.
- Spoon the cookie dough on top of the foil and evenly spread out the batter.
- Cover and bake on high for 2-3 hours (mine takes 2.5 hours).
- Remove the bowl of the slow cooker and place on a wire rack to cool for 20 minutes.
- Carefully grab both ends of the foil and lift out of the slow cooker bowl.
- Place on a large cutting board to cool completely.
- Slice into squares.
- FOR THE FROSTING
- Beat butter for a few minutes with a mixer with a paddle attachment on medium speed.
- Add the powdered sugar and turn on the mixer on the lowest speed to blend.
- Once sugar has been incorporated with the butter, increase the speed of the mixer to medium and add in the vanilla extract and the cream. Beat for 2 minutes.
- If the frosting needs to be thinner, add 1/2 teaspoon more of milk until you’ve reached your desired consistency.
- Spread the frosting over each of the cookie bar squares and top with sprinkles if desired.
