Banana cake with brown butter and cookie butter cream cheese frosting topped with a crumble
Preheat the oven to 350°F / 180° c. In a small bowl, add all the ingredients and rub the butter with the tip of your fingers to crumble.
Spread the mixture on a baking sheet and bake for 15-20 mins or until it is golden brown. Remove from oven and let it cool.
Once the crumble is cooled, store it in an airtight container until needed. This stays fresh for 2 weeks when stored properly. Also use this to top any desserts!
Preheat the oven to 350°F / 180°c. Grease and line the baking tin with parchment.
In a bowl fitted to a paddle attachment on a stand mixer. Add the brown butter, oil and sugar, beat on medium speed.
Add and beat one egg at a time. Add the vanilla and mashed bananas into the mixture .
Sift the dry ingredients (all purpose flour + baking powder) into the wet mixture and mix until completely incorporated (medium speed 2 minutes).
Fold in the chopped nuts. Pour the batter into the prepared tin and bake for about 35-40 minutes or until golden brown and springy to touch.
Once baked, remove from oven and let it cool on a cooling rack.
In a bowl fitted to a paddle attachment on a stand mixer. Add the cream cheese and speculoos and beat on low speed for a minute.
Sift half of the icing sugar into the cream cheese mix. Add and beat the butter on low speed for another minute.
Sift the rest of the icing sugar and whisk on low-medium until the needed consistency. If the frosting seems a little thick add a tsp or 2 of the heavy cream.
If the consistency is a little too runny, add a tsp or two of the icing sugar.
I used a a petal nozzle for the piping (Its a wilton 104), I am sure you can just use a piping bag and the cut the tip at a slant.
Pipe the speculoos frosting on the cake, sprinkle the crumble over and enjoy!
