Preheat oven to 350°.
Combine first 4 ingredients in a large bowl; stir well. Add oil, lemon rind, lemon juice, vanilla, and egg yolks; beat mixture at medium speed of a mixer until smooth. Beat egg whites and cream of tartar at high speed of a mixer until stiff peaks form using clean, dry beaters. Gently stir one-fourth of egg white mixture into batter; gently fold in remaining egg white mixture. Spoon batter into an ungreased 10-inch tube pan, spreading evenly; break air pockets by cutting through batter with a knife. Bake at 350° for 25 minutes or until cake springs back when lightly touched. Invert pan; let cool for 40 minutes.
Combine berries, brandy, and 1 teaspoon granulated sugar in a medium bowl; stir gently. Let stand at room temperature for 30 minutes.
Loosen cake from sides of pan using a narrow metal spatula. Invert cake onto a plate, and sprinkle with powdered sugar. Cut cake into 8 slices, and serve with fruit compote.
