Butterscotch Krispie Cake with Butterscotch Frosting

If you read the blog regularly or maybe semi-regularly you may remember I participate in a wonderful group called Cake Slice Bakers. I have been baking with this group for almost three years and it has been so wonderful!

Today the group turns 5 years old. I think that is pretty significant and so do the other ladies in the group which is why some of use decided to bake cakes as a celebration (check out our birthday cakes on our new Facebook page!).

I didn’t make a traditional birthday for the celebration though. I saw this rice krispie cake Darla had made for Dobby’s birthday and I became obsessed with it.

SIDE NOTE: Yesterday was Harry's, Neville's, and JK Rowling's birthday, so Happy Birthday to them and the group!

I’m slowly starting to fall in love with butterscotch. Last year I made some biscoff butterscotch cookies (they didn’t make it to the blog due to all the cookies being gone before I could take cookies) and they changed my entire perspective on butterscotch.

This “cake” has such a beautiful deep butterscotch flavor due to butterscotch chips strewn throughout and butterscotch sauce (like the kind from Smucker’s). But I also have to give credit to the brown butter frosting that get slathered between the krispie treat layers.

I haven’t worked with browning butter very much. I can count how many times I’ve browned butter on one hand. I don’t think I browned the butter enough for this frosting out of fear for burning it, but it still gave a wonderful caramely flavor.

My favorite part about biting into these was definitely the partially melted butterscotch chips. I think I have officially because a butterscotch lover!

Butterscotch Krispie Treat Cake with Butterscotch Frosting
Adapted from Bakingdom
Makes one 9x13 inch pan

6 cups rice krispie cereal
½ cup butterscotch chips
4 tbsp. unsalted butter, cubed
10 oz. mini marshmallows
¼ cup butterscotch sauce

1 stick unsalted butter, browned and solid
2 cups powdered sugar
Pinch of salt
2 tbsp. butterscotch sauce

Line a 9x13 inch pan with tin foil. Grease foil with cooking spray.

Combine the cereal and butterscotch chips in a large bowl.  Combine marshmallows and butter in a large saucepan set over medium heat. Stir the marshmallows and butter until both are completely melted into each other. Once the marshmallows have melted pour in the butterscotch and stir until combined. The mixture may bubble a little. Pour the cereal into the melted marshmallow mixture and stir until the cereal is completely coated in melted marshmallows.

Press the hot mixture evenly into the prepared pan. Allow to cool completely.

While you wait for the rice krispie treat to cool, make the frosting. Beat the browned butter in the bowl of an electric mixer fitted with a paddle attachment for 30 seconds. Gradually add the powdered sugar. Scrape down the sides of the bowl as necessary. The mixture may look very dry and crumbly. Beat in the salt and the butterscotch sauce. If the frosting is still too dry add a little bit of milk or cream.

To assemble the “cake”: cut the rice krispie treat in half hamburger ways (if you are not an elementary school teacher this means you cut the cake so you have two 9x6 inch rectangles). Place one of the layers on a serving plate. Spread about 2/3 of the frosting on top of the bottom layer. Stack the remaining layer on top of the frosting. Use the remaining frosting to decorate the top of the cake.

  2. Happy 5th Anniversary to you Becca. It has been wonderful to bake along with you and read your posts. I love that you made a rice krispie cake. I am going to have to bookmark this one to make.

  3. Mmmm! Rice crispy treat cake! I love those!
    I've enjoyed baking along with you and seeing your baking skills grow with each cake. Love that your so young and should be interested in other teenage things, but here you are baking with a group of ladies that you should have nothing else in common with. I feel so honored! Thank you for taking time from your busy college schedule to participate baking every month with us. Love to read your post! Your such a wonderful young lady!

  4. These are so cute and I'll have to make them for my granddaughter. Happy Baking!

  5. Becca, I've never tried a rice krispy treat cake before. What a pleasure to see you baking this for our 5th anniversary. This cake looks good. Happy 5!!

  6. Those look amazing! And so feminine too! (is that a weird comment? I just thought so!) :P Thank you for the great addition you brought to our birthday celebration Becca!

  7. I've recently become quite intrigued with butterscotch and I love anything with brown butter, so I definitely want these!!!

    Happy baking with you!

    Happy Anniversary!

  8. Happy birthday to the Cake slice bakers! I remember the group starting when I first started blogging :D

    Your rice krispies look wonderful. I'm not a fan of making rice krispies myself; my kitchen is a sticky mess after they're done. But these look truly delicious.


  9. You've been blogging for over three years? Wow. Congratulations on sticking to something so long! I hope I make it that long. :) And happy birthday to the Cake Slice Bakers group!

    And butterscotch is my favorite flavor! I just hate how difficult it is to make butterscotch goodies healthier. If it were easier, I'd be posting butterscotch all the time. This cake looks like heaven. I honestly can't think of anything more addictive sounding. Rice krispie treats are bad enough on their own (with the whole addictiveness thing) but I would just kill this thing in one sitting.
