Sorting Sweets: KidLit Confections Peanut Butter Chocolate Mousse Pie

Sometimes I read a book and know exactly which recipe from my existing archives will pair perfectly as a #KidLitConfections treat. Sometimes, I create recipes specifically for the books I want to share. And sometimes, like this week, I only find the right recipe after systematically sorting through all of the recipes I have in my stash, trying each one to see if it fits until I find the right pairing...

illustrated cover of CATERWAUL by Anne Marie Stephens and Jenn Harney. Several kittens are helping to pack stacks and stacks of boxes, many of which are labeled with various sorting tags like "red" and "blue" or "keep" and "donate." The kittens aren't being as helpful as you would hope. Two are unspooling rolls of toilet paper and winding it around themselves and everything else. Two are making a ruckus by banging on pots and pans. Others are more interested in playing with the boxes than putting things inside them. The title, CATERWAUL! is displayed in a bold, red and orange font that looks like wide paintbrush strokes diagonally across the top third of the cover. Next to the cover image is a close-up, cropped photo of a slice of Peanut Butter and Chocolate Mousse Pie on a white plate with a pink and green floral border. The pie has a flaky, chocolate crust, with thick, fluffy layers of peanut butter mousse, dark chocolate mousse, and vanilla whipped cream.

When I got the opportunity to read an advance copy of this book, I literally jumped at the chance! The artwork is adorable, the concept is cute, and anyone who knows me could tell you that I'm a huge fan of puns, so a book called CATerwaul about a group of precocious kittens caterwauling about Grandma's upcoming move was right up my alley!

Description from the Publisher:

Math-loving kittens help Grandma pack up her belongings for her move to the Catskill Mountains in this playful picture book that demonstrates the key math concept of sorting.

Nine chaotic kittens are tasked with helping Grandma sort and pack her belongings before the moving van arrives. But they don’t want to see her go, and besides, there’s so much fun stuff to look through! When the moving van pulls up, the kittens can’t help CATerwauling until Grandma helps them sort their feelings and realize that although she may be leaving her house, she’ll always be there for her family. . . . 

Author Ann Marie Stephens draws upon more than 30 years of teaching experience to ensure that readers absorb math while having fun in the adventure-filled A CATastrophe Tale series. Jenn Harney’s energetic illustrations hilariously capture the antics of these enthusiastic kittens.

Each book in the A CATastrophe Tale series includes helpful back matter, which shows readers that, just like the kittens, they use mathematical skills in their everyday lives. Additional titles in the series include CATastrophe!: A Story of Patterns, CATawampus!: A Story of Shapes, and sCATtered!: A Story of Estimation.


My Thoughts:

I always thought I wasn't very good at math. I would point to the amount of time it took me to work out an equation in math class, and the way my brain never wanted to process the answers the same way my teacher taught us to get there... And I would simply sigh and say "I'm just not good at this!" But put me in a kitchen with the task of adapting a recipe to feed a larger (or smaller) crowd than the original specified and with four different ingredient substitutions to accommodate food allergies or dietary preferences (or simply the fact that my budget wouldn't allow for the expensive specialty ingredients required...) and suddenly I could work complex equations in my head to get the recipe proportions just right. Eventually, I realized that I wasn't bad at math. I simply wasn't very good at focusing on the math that didn't feel relevant to my life! I love the way this book introduces an essential mathematical concept in a way that makes it easy and accessible, so young readers can see that yes, they are good at math, even if it's not the kind of math they usually think about!

Beyond the exploration of sorting, this story hits a familiar note that will resonate with almost all readers, at one point or another. The kittens are sad because Grandma is moving to a new house. But they like this house, with it's familiar walls and floors and memories. They don't want her to go! 

Change can be so difficult, at any age. It's easy to focus on the things you'll be leaving behind, and all the things you'll miss. But sorting through those sad feelings to find and focus on the things that will stay the same is so helpful! 


The Recipe:

I'm a huge fan of salty/sweet flavor combinations, and peanut butter is practically made to go with chocolate. So when I made the gluten-free version of my 3.1415926 Ultimate Pie a while ago and I had extra chocolate crusts to play with, I had to try a peanut butter chocolate cream pie, even if I didn't have a book to pair it with yet!

When I first started searching through my recipe files to find the perfect #KidLitConfections creation to pair with this adorable book, I initially thought I'd go with one of my cookie recipes. Perhaps one that has several different variations to the recipe, so I could play on the idea that the cookies could be sorted into subsets by variety... But I also wanted something that leaned heavily toward the category of "comfort food" to reflect the way the kittens find comfort in their sweet memories with Grandma. And the more I looked, the more I kept thinking about the old Reese's Peanut Butter Cups commercials where someone accidentally gets their chocolate into someone else's peanut butter and they discover that the two categories of flavor/texture go perfectly together... So I ultimately came back to this pie, with its layers that can be sorted into three separate flavors (vanilla for the whipped cream, dark chocolate for the chocolate mousse and the crust, and peanut butter for the second mousse) or into two textures (crispy, flaky crust and soft, fluffy cream).

Peanut Butter & Chocolate Mousse Pie

GF Chocolate Crust*:

1 c. butter, softened

1 (8 oz.) block cream cheese, softened

¼ c. heavy cream

¼ c. sugar

1 tsp. salt

3 c. gluten-free, all-purpose flour

¼ c. cocoa powder

 

Peanut Butter Mousse Layer:

1 c. heavy whipping cream

¼ c. powdered sugar

½ tsp. vanilla bean paste

½ tsp. salt

1/3 c. peanut butter

Chocolate Mousse Layer:

1 1/2 c. heavy whipping cream

2 Tbsp. powdered sugar

2-4 Tbsp. cocoa powder

½ tsp. salt

1 tsp. vanilla bean paste

 

Whipped Cream Layer:

1 c. heavy whipping cream

¼ c. powdered sugar

½ tsp. vanilla bean paste

½ tsp. salt

First, make the crust*: In a large mixing bowl, mix together butter, cream cheese, and heavy cream on low speed until smooth. Add sugar and salt. Mix thoroughly. Stir in flour and cocoa powder, until the dough is combined well enough to hold together in a soft ball. Divide the dough into four evenly sized pieces. Shape each piece into a disk that is approximately 1-inch thick, smoothing the edges. Wrap each disc with plastic wrap and refrigerate for 30 minutes to firm up the dough.

Prepare the crust: Place 1 disc of crust dough between 2 large sheets of waxed paper. (Save the other crusts for future desserts!) Roll into a thin circle, approximately 1 ¼” larger all around than your pie tin. Transfer dough to your pie tin and crimp the edges all around. Prick the bottom of the dough all around with a fork, then bake at 400 degrees Fahrenheit for 15 minutes. Set aside to cool.

Peanut Butter Mousse Layer: Whip the cream, powdered sugar, vanilla bean paste, and salt together in a large mixing bowl until stiff peaks form. In a glass measuring cup, melt peanut butter in the microwave, stirring after every 15 seconds or so until it’s pourable but not hot. Carefully drizzle it over the whipped cream. Fold in gently, just to incorporate. Spread evenly in cooled pie crust.

Chocolate Mousse Layer: In large mixing bowl, stir together all ingredients. Whip with wire whisk attachment on your mixer, until stiff peaks form. Gently spoon mousse over peanut butter mousse layer and spread evenly.

Whipped Cream Topping: In a large, clean mixing bowl, whip together heavy cream, vanilla and sugar until soft peaks form. Gently spread over chocolate mousse layer.

Serves 8.

*This Gluten Free Chocolate Pie Crust recipe (adapted from Chef Alina’s Gluten-Free Foolproof Cream Cheese Pie Crust) makes 4 crusts, but you’ll only use 1 for this pie. The extra crusts can be refrigerated for up to four days. Or wrap well and freeze for up to three months. When ready to use your dough, remove from the freezer and let it thaw overnight in the fridge. Then, remove from the fridge and let it rest for 15 minutes or so at room temperature before you roll it out, so it’s not too stiff.

Note: Pie can be frozen (whole or by the slice) in an airtight container. Simply remove from the freezer to thaw in the refrigerator for a couple of hours before serving.
