Crumbly Dessert

One day I had leftover banana cake and I converted it into dessert. Here's how: crumble the cake and spread them on a cookie sheet. Make additional crumbs by mixing some flour, sugar and butter together (no measure here, as long as the mixture resemble crumbs, you're good to go) and sprinkle them on top of the cake crumbs. Then bake until crisp. Quick and easy, right?

Now, the most important part: serve them with ice cream. Enjoy!
