These butter tart bars are a gooey and delicious dessert recipe that are easy to make! They are crisp and delicious on the outside and soft in the middle, giving them the same classic butter tart flavor and texture in a dessert bar.
Preheat oven to 350 degrees Fahrenheit. Grease a 8 x 8 inch baking dish and set aside.
Melt the butter, and place it in a mixing bowl.
To the butter, add in the brown sugar, eggs, and vanilla extract and mix well to combine.
Pour in the flour and baking powder, and mix well until you have a thick batter.
Place the batter into the greased 8 x 8 inch baking dish. Bake in the preheated oven for 30-35 minutes or until the top has browned and the mixture has fully set.
Remove from the oven, and allow to cool fully before slicing.
The texture of the inside will depend on how long you bake the bars. Baking them for 30 to 35 minutes yields a gooey center which is similar to the texture of classic butter tarts. Be sure not to eat undercooked eggs.
Baking the bars longer for 40 to 45 minutes will yield a texture more similar to a dense brownie.
Wait for the bars to fully cool before slicing or enjoying them… I have made the mistake of slicing them when they are still warm and they've become a bit of a gooey mess. Patience is a virtue with these!
