VARIATIONS
You can change the cake in simple ways to fit your taste. Try these ideas in plain words.
- Jam types: Use apricot jam, strawberry jam, or cherry preserves instead of raspberry. Each jam changes the taste a little.
- Colors: Use different food color gels to match holidays or parties. Use blue, purple, and pink for a party, or red, white, and green for a holiday.
- Nut flavor: If you like a stronger nut taste, add a little almond paste on top of the jam before stacking.
- Chocolate: Use dark chocolate or milk chocolate chips for the coating. You can also use white chocolate and color it slightly for a different look.
- Shape: Make smaller square cakes for party bites instead of one large stack.
- Gluten-free: Try a gluten-free white cake mix and check that almond paste is gluten-free.
FAQs
Q: Can I use regular food coloring instead of gel?
A: Yes. You can use regular liquid food coloring. Gel color gives richer hues with less liquid. If you use liquid color, add a little more to reach the shade you want.
Q: Can I make the batter by hand without a mixer?
A: You can mix by hand, but the batter will be thicker and take more work. Use a strong whisk and beat well to make it smooth.
Q: Do I need to chill the cake for 4 hours?
A: Chilling helps the layers set and makes slicing neat. You can chill for less time, but the cake may crumble or the chocolate may crack when you slice it.
Q: How thin should I slice the cake?
A: Slice thin, about 1/4 inch to 1/3 inch. Thin slices show the layers and make the cake easier to eat like a cookie.
Q: Can I make the cake ahead for a party?
A: Yes. You can make and chill the cake a day ahead. Keep it wrapped and cold until you serve. See the make-ahead tips below for more ideas.
Q: How do I melt the chocolate without burning it?
A: Use a double boiler or heat in short bursts in the microwave (20 to 30 seconds), stirring each time until smooth. Add the teaspoon of shortening to help the chocolate stay glossy.
