Preheat the oven to 350°F.
Grab a cutting board and a non-serrated knife. Open up your can of biscuits and divide them in half. (The can I used came with 10 biscuits so I made two piles of five.) Then cut each biscuit into quarters. Do the same with the other pile of biscuits but keep them separate from the first group.
Next, grab a sandwich or quart sized resealable bag and dump 1/2 c. sugar and 2 Tbsp cinnamon into it. Close it and shake until combined. Open it back up and put the quartered pieces of biscuit into the bag. Reseal the bag and shake, shake, shake. *Note: I found it was best to put them in one at a time instead of throwing a whole handful in, otherwise they stuck together and didn't get evenly coated with the cinnamon sugar mixture. You may need to open up the bag part way through your shaking and separate some of the pieces that have stuck together.
After they are covered with the cinnamon sugar, prep your pans by spraying them with some cooking spray. Then pull the biscuit pieces out of the bag and throw them into the pan. DO NOT just dump everything into the pan because you still have the second batch of biscuits to coat in cinnamon sugar. Repeat the cinnamon sugar coating process with the second batch of biscuits and put them in the other pan.
Once you have the biscuits in the pan, sprinkle some of the cinnamon sugar over the top.
In a small saucepan, combine the 1/4 c. butter, 1/3 c. brown sugar and 1/4 tsp. cinnamon. Melt together and stir on medium low heat until completely melted and combined. You do not need to let it stay on the heat longer than it takes to mix it all together. Remove from the heat and pour over the top of your cinnamon sugar biscuits, dividing it as evenly as possible between the them.
Put the pans on top of a larger baking sheet with a silicone baking mat underneath or something to cover it in case there is a little overflow. This also makes it easier to put it in and take it out of the oven. Place in the oven and bake for 17-23 minutes.
When done, remove from the oven and let cool for 3-4 minutes. Then turn them over onto a plate and drizzle with a little bit of frosting. I used some leftover cream cheese frosting.
*Note: If you just want a basic icing, you can combine a little bit of milk, powdered sugar and softened butter in a bowl and mix until combined with a medium consistency. If it's too thick to drizzle, put it in the microwave for a few seconds to soften it up.
