Cookie ingredients
- All-purpose flour: sift flour before using to eliminate any lumps.
- Cornstarch, baking soda and ground cinnamon
- Butter: use unsalted butter at room temperature. The butter and sugars are creamed together to help aerate the cake. Cold butter will not aerate as well as room temperature butter.
- Brown sugar and granulated sugar: light brown or dark brown sugar may be used
- Egg: use a room temperature egg. Cold eggs can cause the butter to curdle when creating the cake batter.
- Sour cream: use full-fat, room temperature sour cream.
- Bananas: use ripe bananas. Mash bananas well before adding to the cookie dough.
See recipe card for quantities.
Filling ingredients
- Butter: use unsalted butter
- Heavy cream: you may use whole milk or half & half to replace the heavy cream.
- Chocolate chips: use bittersweet or semisweet chocolate chips.
See recipe card for quantities.
Cookie instructions
In a medium bowl, whisk together flour, baking soda, cornstarch and ground cinnamon (sift ingredients together if flour is lumpy). Set aside.
Using a stand mixer with the paddle attachment or a hand mixer, begin creaming the butter, brown sugar and granulated sugar until light and fluffy (2 - 4 minutes on medium speed). Scrape the bowl as needed.
Add the egg and sour cream to the bowl. Mix on medium speed until incorporated. Scrape the bowl as needed.
Add mashed bananas to the bowl. Mix on medium speed until incorporated. Scrape the bowl as needed.
Add flour mixture and mix on low speed until combined. Place mixing bowl in refrigerator for approximately 1 hour. This allows the flavors to develop and the cookie dough will firm up.
Scoop 1 ½ tablespoon of the dough using a cookie scoop or spoon. Place onto parchment-lined baking sheets leaving approximately 2 inches of space between each cookie. Using your palm or the bottom of a round drinking glass, flatten the cookie slightly. Bake cookies for 10 - 12 minutes.
Sandwich cookie assembly
Place chocolate chips in a medium-sized heat-proof bowl and set aside. Put butter and heavy cream in a small saucepan. Place saucepan on the stovetop and bring to a low boil over medium heat, stirring often. Remove saucepan from the heat and pour over the chocolate chips. Let set for 5 minutes to soften chocolate, Stir until smooth. Set bowl aside until filling reaches a spreadable consistency (approximately ½ hour at room temperature).
Arrange the cookies in pairs by matching up similar sized cookies. Pipe or spoon approximately 2 teaspoons fudge filling onto the flat side of half of the cookies. Sandwich with the remaining cookies and gently press until the filling reaches the edges.
Variations
