Start by preheating your oven to 350 degrees and lightly spraying a bundt pan non stick spray
In a small bowl combine brown sugar, cinnamon, allspice and salt. Melt your butter in a microwave safe bowl for approximately 1 minute and set aside.
Cut each biscuit in half and then half again so that each biscuit is in 4 equal pieces.
Dice your apples into small bite size pieces. It is not necessary to peel your apples first but feel free if you are so inclined.
Start by sprinkling a light layer of apple and walnuts into the pan. Dip each piece of biscuit into the butter and then the brown sugar. Gently roll your biscuit piece around and generously coat with the brown sugar mixture.
Place biscuit pieces into the bottom of the pan (on top of the apple and walnut pieces) and continue to do this until you have a full layer around the pan.
Sprinkle in 1/3 of the walnuts and apples on top of the biscuit layer. Continue making layers (about three) until all your ingredients are used up.
Place bundt pan on a baking sheet and bake for 35 minutes or until your inner layer of biscuit pieces is cooked. Let sit for 10 minutes and then flip upside onto a serving plate.
While cooling, make your icing drizzle by sifting the powdered sugar then whisking it together with the vanilla and milk in a small bowl. Drizzle over the top of your Apple Fritter Monkey Bread and serve immediately
