Peanut Butter Sandwich Cookies
I wanted to make some sort of peanut butter cookies for our beer pong finals. I think the saltiness of the peanut butter goes really well with beer 🙂 The cookies themselves actually have no peanut butter in them, but the filling does so it fits the bill. I made a double batch and got 2.5 dozen cookie sandwiches.
Peanut Butter Sandwich Cookies – from Fresh from Cate’s Kitchen
1 1/2 cups flour
1/2 tsp baking soda
1/2 tsp cinnamon
1 cup quick oats
1 cup light brown sugar
1 stick butter, softened
1 large egg
1 tsp vanilla
Whisk together flour, baking soda, cinnamon, and oats in a medium bowl.
In a separate bowl, cream the butter and brown sugar until fluffy.
Beat in vanilla and egg, then stir in dry ingredients until just combined.
Roll about 2 tsp of dough into a ball, then flatten and press onto a Silpat-lined baking sheet.
Repeat with remaining dough.
Bake at 350 for 8-12 minutes (closer to 8 for softer cookies, closer to 12 for crisper cookies).
Cool on a wire rack.
Filling3/4 cup creamy peanut butter
1/4 cup butter, softened
2 tbsp half and half – I used goat’s milk
1 tsp vanilla
1 1/2 cups powdered sugar
Beat all ingredients together in the bowl of an electric mixer until smooth.
When cookies are cool, pipe or spread frosting on one and press another on top to make a sandwich.
Note – My frosting was very thick so I ended up double the amount of liquid by adding more milk. You will have some extra frosting. But it’s amazing so no big deal there.

I am going to try this today on a chocolate layer cake that I found the recipe for on epicurious…. Wish me luck! I will post how it turns out…..
I don’t have an electric mixer. can this be made by hand and get the same consistency? I’m finding mine runny.
How long does the frosting keep in the fridge? Can I leave it for two days?

It will be fine in the fridge for a week or so.
wil this work with home-made cream cheese? I make my own from sour cream by draining the liquids from it overnight in a cloth…

While I haven’t tried it myself, I don’t see why it wouldn’t work. I’d love to hear how it turns out for you.
How do I keep cream cheese frosting from being so runny that the frosted cake has to be kept in the fridge? Are there proportion formulas, e.g., 1 part cream cheese : 1 part butter : 2 parts powdered sugar for a firm frosting?

I use this recipe for frosting a cake. If you need to make it more stiff, add more sugar.
