Preheat the oven to 350°F.

Grease an 8" x 8" baking dish with butter or cooking spray.

Combine the dry ingredients into a mixing bowl. In a separate bowl, whisk all the wet ingredients together.

Slowly add the dry ingredients to the wet mixture, stirring as you go. Mix until just combined.

Fill the greased baking dish with your brownie mixture and spread out evenly. Use a spatula to level the top.

Bake for 22-30 minutes, depending on how fudgy you want them to be. Leave to cool completely.

Use your fingers to crumble the brownie pieces into a bowl. Test whether they stick together by squeezing a handful in your hand. If not, add some frosting to help the pieces stick together.

Squeeze the brownie crumbs together to create tall cone shapes. The exterior should be smooth.

Dust with powdered sugar to serve.
