How to make cake like almond squares into fudgy like Squares? I made Almond Paste Squares that turned out delicious, but too cake like for what I wanted.  The recipe had these ingredients: 1 C butter, softened; 1 C flour; 2/3 C sugar; 1 tsp baking powder; 3 eggs. Then this 1 C almond paste; 2/3 C granulated sugar; 2 eggs; 1 tsp almond flavoring; Sliced almonds, Opt.  The two batters then mixed together.
What can I do to make these more fudgy like brownies?
A hint is that a lot of brownie recipes don't include any leavening agent at all, so I recommend you reduce the baking powder amount, to about 1/2 tsp.
Also, it may help to replace part of the whole eggs with egg-yolks, as the richness in the yolks make for a fudgier treat.
