Rocky Mountain Bars

If chocolate chip bars aren’t enough for you today, here’s something a little more over the top. The recipe is from a cookbook I got for Valentine’s Day called “Creme de Colorado” by the Junior League of Colorado. At first it reminded me of Mississippi Mud Bars, but then I saw there were several differences including the addition of cream cheese. What you get in the end is a layer of nutty brownies topped with a rich chocolate chip and nut cheesecake topped with puffed marshmallows and a final layer of sweet chocolate cream cheese icing. If that’s not enough for you than I don’t know what is.

From the start, I knew these would be a gooey mess if I didn’t allow them a good chill time, so I started these yesterday morning and let them chill all day before cutting in squares. I sent them to work with Todd and hope they go over well.

Update: A few people pointed out that this recipe was an old Bake-Off entry from 1972 called Rocky Road Fudge Bars. It has great reviews on Pillsbury, and I am happy to say the ones I sent to work with my husband got great reviews as well!

Rocky Mountain Bars
Recipe type: Dessert
Cuisine: American
Serves: 24
  • 1/2 cup butter (salted)
  • 1 oz unsweetened chocolate
  • 2 large eggs
  • 1 cup granulated sugar
  • 1 tsp vanilla
  • 1 cup all purpose flour
  • 1 tsp baking powder
  • 1/2 cup chopped nuts (toasted pecans)
  • 6 oz cream cheese, softened
  • 4 tablespoons softened butter (salted)
  • 1/2 cup granulated sugar
  • 1 large egg
  • 1/2 tsp vanilla
  • 2 tablespoons flour
  • 1/4 cup chopped nuts (toasted pecans
  • 6 oz chocolate chips (dark)
  • 2 cups mini marshmallows
  • 4 tablespoons butter
  • 1 oz unsweetened chocolate
  • 2 oz cream cheese, softened
  • 1/4 cup whole milk
  • 1 tsp vanilla
  • 3 cups powdered sugar
  1. Preheat oven to 350 degrees F. Line a 13x9 inch metal pan with foil and spray with cooking spray or Baker's Joy.
  2. Melt butter and chocolate together in the microwave and set aside to cool slightly. Meanwhile, in a mixing bowl, beat eggs, sugar and vanilla until light and fluffy. Add melted chocolate mixture to eggs and beat well. Mix together flour and baking powder and stir (do not overbeat) into the batter along with the nuts. Spread in prepared pan and set aside.
  3. In another bowl, beat together cream cheese, butter, and sugar until fluffy. Add the egg, vanilla and flour and stir just until mixed. Stir in nuts and spread batter in the pan covering the chocolate mixture. Sprinkle with chocolate chips. Bake at 350 F for 30 minutes. Remove from the oven and sprinkle with marshmallows. Return to oven for 2 minutes to puff marshmallows.
  4. Frosting: Melt the butter and chocolate in a microwave-safe bowl and let cool. In a mixing bowl, beat melted chocolate mixture, cream cheese, milk, vanilla and powdered sugar until smooth. Spread over marshmallow layer. When I did this, I couldn't cover the entire layer of marshmallows and ended up leaving about 1/2 to 1 inch edges. Cool completely in the pan, then transfer to the refrigerator and chill for a good 4 hours or so.
  5. When ready to cut, lift from pan and set on a big cutting board. With a chef's knife, trim the edges where the chocolate frosting did not reach. Now score the cake in half, then score each half into 12 bars so that you get 24 bars total.

    I have “Creme de Colorado”, but have never made these. I’ll be interested to hear the co-worker verdict. What did you think?

    I thought your recipe looked interesting so I compared it to my Rocky Road Fudge Bars that I got years ago from Portland’s Palate. The recipes are exactly the same, so this must be an old recipe. I will vouch for it – it is absolutely fantastically delicious; people can hardly stop eating it!

    Where would these lie on the “sweetness scale”?

    And there must be a way to cram peanut butter into that thing 🙂 — that would be pretty ultimate :).

    Creme de Colorado is a great book. I think you will enjoy it! The Junior League of Denver has done four excellent cookbooks. (I wasn’t crazy about the 5th and most recent one but it seemed to have more meat recipes than the others and I am vegetarian.) I think C de CO has the breckenridge Bars which are very good!

    @Adam: Your Peanut Butter suggestion is EPIC!

    I’d rather sub the peanut butter suggestion for the marshmallow layer…

    Oh no… I think I’m gonna get into trouble with these.

    Oh man, these bring back memories of childhood! My mom used to always make these for us, and up until now I could never remember the name! Must. Make. Now. 🙂
