The Holmesburg bakery in Philly has the best buttercake...this is as close to the original as you can get when not living in or visiting Philly.
How to Make Philadelphia Buttercake
- Mix cake mix, butter and egg to make a smooth dough. Pat it with your hands into the bottom of an ungreased 9x13 pan
- Best cream cheese with electric mixer until fluffy about 1 min. Add eggs, vanilla & butter & beat for an additional minute. Add sugar and beat 1 min.
- Pour over crust & spread to the edges. Bake at 350 until brown & firm,about 45 mins
