What I would do differently when I make it again is not try to replicate the shape of how Red Robin does theirs. I would start with an Oreo pie crust, then line that with the peanut butter sauce (recipe to follow), vanilla ice cream, crushed Nutter Butter cookies, and chocolate ice cream, frosted with hot fudge, using less ingredients of everything so it all fits in the pie shell. Here's the original recipe.
Red Robin® Mountain High Ice Cream Pie ingredients
Makes 12 servings
6 cups chocolate ice cream
1 cup peanut butter cookie pieces
6 cups vanilla ice cream
1 2/3 cups creamy peanut butter
3/4 cup chopped peanuts
4 chocolate-flavored graham crackers, crushed
1 cup fudge topping
1 (20-oz) squirt bottle chocolate topping
1 (20-oz) squirt bottle caramel topping
Garnish:
Chocolate sauce
1 can Redi-Whip
3/4 cup chopped peanuts
12 maraschino cherries, with stems
Notes:
Directions
Line a 3-QT bowl with Saran wrap and freeze for at least 30 minutes.
Soften the chocolate ice cream and pack it into the bottom of prepared bowl. Make sure the surface of the ice cream is smooth and leveled.
Evenly spread the peanut butter cookie pieces over the top; cover the bowl and freeze for at least one hour.
Then, soften the vanilla ice cream and spread it over the peanut butter cookie layer, again smoothing a level ice cream surface. Cover the bowl and freeze again for at least one hour.
After the vanilla ice cream is hardened, use a spatula to spread 2/3 cup of peanut butter over the top.
Evenly spread the chocolate graham cracker crumbs over the peanut butter. Cover the bowl and freeze again for at least one hour, preferably longer.
About five hours before serving, partially fill a sink with warm water. Then, remove ice cream bowl from the freezer and hold it in the warm water for about one minute; you want the ice cream around the edges to soften just enough that you can invert the domed-shaped ice cream onto a plate.
Turn a large plate upside down and place it on top of the ice cream bowl; flip bowl and plate together, gently tapping on bowl until the ice cream dome falls onto the plate. You may have to immerse the bowl in warm water again to release the ice cream dome.
Once released on the plate, cover the ice cream dome with plastic wrap and place it in the freezer for another 1 - 2 hours.
Without heating, evenly spread the fudge sauce over the entire surface of the ice cream dome ("mountain"); freeze for 1 hour.
When the fudge sauce has hardened, spread the remaining 1 cup of peanut butter over the entire surface as well; freeze again for 1 hour.
About one hour before serving, use a warm knife to slice dessert into 12 pieces. Place wax paper between the cuts so it is easy to divide when you serve it later. Then cover and return to freezer. If desired, freeze dessert plates, too.
Just before serving (finally!), and on each serving plate, use squirt bottle of chocolate topping to make 3 parallel (side by side) lines.
Make quarter-turn of each serving plate and use squirt bottle of caramel topping to make 3 parallel (side by side) lines which are perpendicular to the chocolate lines.
Turn each serving plate so the lines appear as an "X."
Near the back of the "X" design, place a slice of ice cream upright onto each serving plate; spray generous amount of Redi-Whip on top and down the curved edge of the slice, onto the plate over the sauces.
Sprinkle about a tablespoon of chopped nuts over the Redi-Whip on each plate; add a cherry on top and serve immediately.
Peanut butter sauce- (adapted slightly)
INGREDIENTS
- 1/2 cup heavy whipping cream ( you can use half and half)
- 1/4 cup sugar
- 1/4 cup light Karo syrup
- 2 tablespoons butter
- 1 teaspoon vanilla
- 2/3 cup creamy peanut butter
INSTRUCTIONS
- Combine all ingredients (except peanut butter) in a saucepan stirring constantly until all ingredients are dissolved.
- Let the mixture cool completely then add the peanut butter and stir well.
- It will look like a mess, but keep stirring and it will turn out smooth and still have the grain texture.
