Preheat the oven to 350-degrees and grease an 11×17 jelly roll pan.
In large mixer cream together the softened butter and the sugar. Then add 1 egg at a time (it is best to crack eggs in a separate bowl then add them to the mixer.
Add vanilla and almond extracts, and then carefully add the flour, a little at a time, until incorporated. The batter will be very thick.
Spread two-thirds of the batter evenly into the prepared pan. Add 1-2 cans of fruit filling on top of batter, spreading evenly.
Finally, add the remaining batter on top of filling dotting it all over top so that there is batter in some places and filling in others, which will give it the marbled look.
Bake until top and edges are slightly brown (about 45-55 minutes). Cool completely before cutting into squares.
Notes
