- 12 tbsp / 168 grams plant based butter with salt - room temperature
- 3 tbsp plant based heavy cream - cold
- 1 tbsp vanilla extract
- 70 grams green banana - sliced and quartered
Instructions
Biscoff Cookies
- To a small bowl, add the flour, baking soda and baking powder; whisk to combine and set the bowl aside.
- To a medium bowl, add the butter, Biscoff cookie butter, cane sugar and coconut sugar. Using a hand mixer, blend the ingredients together on medium-high speed for 2 minutes. Add the milk and vanilla extract and continue blending on medium-high speed for another 30 seconds.
- Add the dry ingredients to the wet ingredients, blend the ingredients together with the hand mixer on medium speed just until no more flour can be seen.
- Place the cookie dough in the refrigerator. Preheat the oven to 350F and line two cookie sheets with parchment paper.
- Once the oven reaches temperature, you can begin scooping the cookies. Scoop 2 tablespoon size cookie dough balls, roll them between your palms to smooth them out and place them on the prepared pans. Flatten each dough ball into a thick disk and dip the tops into the turbinado sugar. Return the cookie dough back to the refrigerator between batches.
- Bake the cookies for 11 to 13 minutes - mine baked perfectly at 12 minutes. Allow the cookies to cool on the pan for 5 to 10 minutes before transferring them to a cooling rack. The cookies need to cool to room temperature before frosting.
Banana Buttercream
- To the bowl of a stand mixer, add the butter and banana. Cream the butter and banana on high with a balloon whisk attachment for 2 minutes. *** A greener banana works better for the buttercream; it has less moisture. The riper the banana the looser the buttercream will be.
- Add the powdered sugar and continue blending on high for another 30 seconds to 1 minute. Add the heavy cream and vanilla extract and continue blending at high speed for 3 minutes. ***If the buttercream seems too loose to pipe, place it in the refrigerator for 15 to 20 minutes to firm up before placing it in the piping bag.
Assembly
- Take half of your cookies and place them bottom side up and pair them with a similar sized cookie positioned bottom side down. Place the banana buttercream in a piping bag, fitted with the piping tip of your choice. You can also add the buttercream to the cookies with a knife if you prefer. Pipe equal amounts of buttercream to half of the cookies - the half with the bottom facing up. Place the frosted cookie's pair on top of the frosting. The cookies are ready to serve.Store the cookies in an airtight container at room temperature.
