Step 1

Preheat the oven at 350-degree F.

Step 2

Melt the butter on low heat in a small saucepan and pour it into an 8 by 8 inches baking dish or casserole pan.

Step 3

Now, take a medium-sized mixing bowl, mix all the dry ingredients; all-purpose flour, wheat flour, sugar, brown sugar, baking powder, cinnamon, nutmeg, cardamom, and salt.

Step 4

Pour the milk, dark rum, and vanilla into the dry mixture. With the help of a fork, mix them until no flour particles are visible.

Step 5

Now gently sprinkle the mixture over the melted butter in the dish into an even layer. Do not stir the butter and the mixture.

Step 6

With the help of the back of a spoon, press the batter down into a smooth and even layer.

Step 7

In a medium bowl, mix light brown sugar, toffee bits, and pecans.

Step 8

Sprinkle the pecan mixture over the batter in the casserole. It might seem a lot, but it is the perfect quantity for a cobbler. Do not stir the topping in too.

Step 9

Now carefully, pour the boiling hot water over the pie. Cover the whole surface and do not stir. It will look like a wet mess but worth it.

Step 10

Carefully and gently place the dish in the preheated oven for 25 to 30 minutes until bubbling and golden.

Step 11

Finally, let it cool on a cooling rack for 15 to 20 minutes.

Step 12

Serve warm with a dollop of whipping cream over or on the side.
