Mystery Squares: A Culinary Surprise

Growing up, I always looked forward to Tuesdays. It wasn’t for any specific reason other than that’s when my mom would bake. The aroma of warm butter and sugar would fill the house, a comforting beacon that signaled something special was about to emerge from the oven. While she made a lot of delicious desserts, there was one treat that always stood out: Mystery Squares. We called them that because every bite was a delightful surprise of textures and flavors. Even now, decades later, the taste transports me back to her kitchen, a place filled with love, laughter, and the comforting aroma of baking.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 35 minutes
• Total Time: 55 minutes
• Yields: 18 squares
• Serves: 18
• Dietary Type: Not specified

Ingredients

• For the Base:
  • 1 cup butter
  • 2 cups flour
  • 1/2 cup icing sugar
• For the Middle Layer:
  • 2 eggs, beaten
  • 1 1/4 cups brown sugar
  • 2 tablespoons flour
  • 1 teaspoon baking powder
  • 1 cup coconut
  • 3/4 cup maraschino cherries, chopped
  • 1/2 cup walnuts, chopped
• For the Topping:
  • 2 cups frosting, your choice

Equipment Needed

• 9×13 inch baking pan
• Mixing bowls
• Measuring cups and spoons
• Electric mixer (optional)
• Oven

Instructions

1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan. This is crucial to prevent the squares from sticking.

2. Prepare the base: In a large mixing bowl, combine 1 cup of butter (softened), 2 cups of flour, and 1/2 cup of icing sugar. Mix well until the mixture resembles coarse crumbs. An electric mixer can speed up this process, but it’s equally effective to use your hands to rub the butter into the flour and sugar.

3. Press the mixture into the prepared 9×13 inch pan, creating an even layer.

4. Bake the base at 350°F (175°C) for 10 minutes. This par-baking ensures the crust is sturdy enough to support the middle layer. Remove the pan from the oven and let it cool slightly while you prepare the filling.

5. Prepare the middle layer: In a separate mixing bowl, combine the 2 beaten eggs, 1 1/4 cups of brown sugar, 2 tablespoons of flour, 1 teaspoon of baking powder, 1 cup of coconut, 3/4 cup of chopped maraschino cherries, and 1/2 cup of chopped walnuts. Mix all ingredients thoroughly until well combined.

6. Pour the middle layer mixture evenly over the par-baked base.

7. Bake the assembled squares at 350°F (175°C) for 25 minutes, or until the top is golden brown and the filling is set. A toothpick inserted into the center should come out clean, though a few moist crumbs are acceptable.

8. Remove the pan from the oven and let it cool completely on a wire rack. Cooling completely before frosting is essential; otherwise, the frosting will melt.

9. Once completely cool, spread the 2 cups of frosting of your choice evenly over the top. My personal favorite is a classic buttercream, but cream cheese frosting or even a simple glaze would also work beautifully.

10. Sprinkle with chopped walnuts, if desired, for added texture and visual appeal.

11. Cut the squares into 18 pieces and serve.

Expert Tips & Tricks

• For the best flavor, use high-quality ingredients. Real butter, fresh eggs, and flavorful nuts will make a noticeable difference.
• If you want a chewier base, substitute part of the flour with almond flour.
• To prevent the maraschino cherries from sinking to the bottom of the filling, lightly toss them in flour before adding them to the batter.
• Don’t overbake the squares, as this will result in a dry and crumbly texture.
• For easier cutting, chill the squares in the refrigerator for at least 30 minutes before slicing.
• If you find that the top of the squares is browning too quickly during baking, tent the pan with aluminum foil.
• Customize the frosting to your liking. Add a few drops of food coloring for a festive touch, or incorporate extracts like vanilla, almond, or lemon for added flavor.
• Make ahead: The squares can be baked a day in advance and stored in an airtight container at room temperature. Frost just before serving.

Serving & Storage Suggestions

Serve the Mystery Squares chilled or at room temperature. They are a perfect dessert for potlucks, parties, or simply enjoying with a cup of coffee or tea. Leftover squares can be stored in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. For longer storage, freeze the squares in a single layer on a baking sheet, then transfer them to a freezer-safe bag or container. They can be frozen for up to 2 months. Thaw overnight in the refrigerator before serving.

Variations & Substitutions

• Gluten-Free: Substitute the all-purpose flour with a gluten-free blend. Be sure to check that your baking powder is also gluten-free.
• Nut-Free: Omit the walnuts and substitute with sunflower seeds or pumpkin seeds for a similar textural element.
• Cherry Alternatives: If you’re not a fan of maraschino cherries, use dried cranberries, raisins, or chopped candied fruit instead.
• Frosting Variations: Experiment with different frosting flavors. Chocolate, caramel, or even a peanut butter frosting would be delicious. A simple dusting of powdered sugar is another great option if you prefer a less sweet topping.
• Seasonal Twist: Add a pinch of cinnamon or nutmeg to the filling for a warm, autumnal flavor.

FAQs (Frequently Asked Questions)
