To begin, make sure you have the necessary ingredients.
In a mixing bowl, add your favorite box of cake mix (I used Betty Crockers Chocolate Fudge here, but have also used Funfetti and Yellow cake mix before), 1/3 cup vegetable oil, and 2 eggs.
Put the glass bowl containing the chocolate chips into the microwave on HIGH for 45 seconds.
Remove the bowl, mix with a non-stick rubber policeman or wooden spoon. Re-heat the mix in 45 second intervals in the microwave until this is fully mixed and smooth. Its very easy to burn chocolate, so stick to short intervals and you should be ok. This usually fully melts in approximately three 45 second cycles.
Time to set the oven to 350F, allow it to pre-heat for at least 10 minutes.
While melting the chocolate chips, start to mix the cake portion by hand. This is best done using a large rubber policeman and folding the batter onto itself. This will eventually form a VERY thick batter. I would not suggest using an electric mixer for this as it will likely get stuck.
And voila! This will be the base for the snack. Continue to fold this onto itself until the resulting batter is smooth (no visible dry cake mix left).
Using a 13x9x2" well greased or non-stick glass/metal pan, place 2/3 of the cake mix batter into it and spread evenly across the bottom.
Next, pour the molten chocolate mixture on top of the batter and try to get it to spread evenly across the top.
Using the remaining 1/3 cake mix, make several "balls" or "disks" to place on top of the chocolate. Try to spread these evenly across the top.
This is the final result before baking. I've used several small balls of dough before, but I prefer the "disks" better as they tend to spread better during the bake. Place this into the oven for 20-25 minutes. This is done once the cake portions on top start to lightly brown.
This is the final result. Aptly named "Can't Leave Em' Alone Bars" they combine the texture of brownies with a smooth creamy chocolate center. Similar to substituting the cake mix, you can also use white chocolate or peanut butter chips (or others...) to yield the same result for an endless combination of flavors! Enjoy!!
