Chocolate & Peanut Butter Streusel

Chocolate & Peanut Butter Streusel Bars

I found this recipe on the site linked in the title there. Be sure to have people to give it away to, because there's a lot of this to go around! 

Ingredients
1 cup heavy cream
12 ounces (about 2 cups) 60% chocolate, finely chopped
1 1/2 sticks unsalted butter, at room temperature
3/4 cup sugar
3/4 cup brown sugar, tightly packed
1 teaspoon vanilla extract
2 extra-large eggs, at room temperature
2 cups (18 ounces) creamy peanut butter (not “natural”)
2 cups all-purpose flour
1 cup whole-wheat pastry flour or spelt flour (can substitute all-purpose flour)
1 teaspoon baking powder
1 teaspoon kosher salt (or 1/2 teaspoon table salt)

Directions

1. Preheat the oven to 350° F. Grease and flour an 11×14-inch cake pan.
2. Bring cream to a boil in a small, heavy saucepan. Place the chocolate in a medium bowl, and pour cream over chocolate. Mash any big pieces with a wooden spoon. Whisk until smooth. Set aside.
3. With an electric beater on medium speed, cream the butter and sugars in a large bowl until light yellow, about 2 minutes. With the mixer on low speed, add the vanilla, eggs, and peanut butter and mix until combined.
4. In a small bowl, whisk together the flour, baking powder, and salt. With the mixer on low speed, slowly add the flour mixture to the peanut butter mixture. Mix just until combined.
5. Place 2/3 of the dough into the pan. Spread and press over the bottom with your fingers. Spread the ganache evenly over the dough. Form the remaining dough into pea-sized globs (it takes a while, but it ensures that the crumbs stay chunky). Drop the dough evenly over the ganache. Bake for 45 minutes, or until golden brown. Cool and cut into 1 1/2-inch squares.
