Preheat the oven to 180c / 350f and line a baking sheet with parchment paper.
In a mixing bowl, mix softened butter, honey, brown sugar, and vanilla extract until well combined.
Now, with a butter knife, spread a thin layer of the mixer all over the toast, covering the sides and the edges.
Now, transfer the toast to the prepared baking sheet and bake in the oven for 10 minutes. Flip the toast on the other side and bake for 5 more minutes until crispy and golden brown.
Now allow the toast to cool and firm for 10 minutes then enjoy!
Notes
The toast comes out of the oven soft; let it set for 5-10 minutes to harden.
