First make the Red Heart Cake. Cream the butter and sugar in a large bowl till fluffy. Beat in the eggs one at a time. Sift together the flour, baking powder and the cocoa powder, if using, fold it in the mixture in the bowl along with the powdered almonds (powdered whole almonds are fine). Fold these in. Mix together the milk, the vanilla extract and the red food colouring in a small bowl. Mix this into the batter till even and no streaks of red are seen.
