Chocolate Chip Toffee Oatmeal Cookies with Peanut Butter Frosting

Yes, I’m still making cookies.  I just can’t help myself, though!  And believe me, you should be happy about this.

A few months ago I made some oatmeal cookies with toffee and chocolate that were delicious.  The cookie wasn’t exciting enough, though so I stepped them up.

This time I made Chocolate Chip Toffee Oatmeal Cookie Sandwiches with Peanut Butter Frosting.  Chocolate. Toffee. Peanut Butter. Love it.

Chocolate Chip Toffee Oatmeal Cookies with Peanut Butter Frosting

These mini cookie sandwiches are perfect for a plate sampler.  If your name was Matt, I’d say these were 2-bite cookies.  For the rest of us, however, it is more like 3 or 4 bites.

The cookies are soft and chewy and the peanut butter frosting is sweet, salty, and thick.  It is the perfect consistency for holding the the sandwiches together.

Each component is easy to make, it is just a matter of taking the time for both recipes as well as making them into sandwiches.  Matt actually helped with that part so it didn’t take long at all.  Peanut butter recipes are the best ones for my husband to help with since I won’t have to worry about him eating most of the work!

Chocolate Chip Toffee Oatmeal Cookies with Peanut Butter Frosting

I recommend making your cookies the day before the frosting so that you can freeze them before icing them.  Otherwise, the soft cookies can be a little too fragile and might break during the sandwich making.  I didn’t include cookie-making photos, but for sizing the dough balls refer to this post

Beat butter and peanut butter on high until creamy

Reduce speed to low and gradually add in Half & Half and then vanilla

pour half and half

Gradually add sugar until completely combined

When frosting is done, gently spread on bottom half of cookie and cover with another cookie to make sandwich

  1. Whisk together flour, cinnamon, and baking soda; set aside
  2. Beat butter and sugars in an electric mixer on high until light and fluffy

  8. Place dough balls of about ½ tablespoon 1 inch apart from one another on a baking sheet lined with parchment paper
  9. Bake 9-10 minutes or until cookies are golden brown

Peanut Butter Frosting

Yield: Makes ~3 cups of frosting


  • 1 cup smooth salted peanut butter (I used natural)
  • ¼ cup (4 tablespoons) unsalted butter, softened
  • 10 tablespoons Half & Half (can substitute cream) (plus more as needed)
  • 1 teaspoon vanilla
  • 3 ½ cups confectioners’ sugar (plus more as needed)

Cooking Directions

  1. Beat butter and peanut butter on high until creamy
  2. Reduce speed to low and gradually add in Half & Half
  3. Mix in vanilla
  4. Gradually add sugar until completely combined

To make the sandwiches:


Spread a layer of frosting onto the bottom of a cookie

Top with a second cookie and lightly press down

Repeat until all of your cookie sandwiches are complete

Frosting recipe adapted from

I recommend making your cookies the day before the frosting so that you can freeze them before icing; this will keep them from breaking while putting sandwiches together

If frosting is too thick, add half & half, 1 tablespoon at a time until frosting reaches desired consistency

If frosting is not thick enough, add confectioners’ sugar, ¼ cup at a time until frosting reaches desired consistency

    The toffee, oat, chocolate, peanut better combination sounds divine, and I love your twist on cookies by making them frosted in sandwiches. That seems like it would make each cookie more satisfying and of course frosting makes everything better.
