Ingredients

  • 1/2 box cake mix (yellow, white, or lemon)
  • 1 egg
  • 1 can crushed pineapple
  • Brown sugar

Instructions

  1. Mix half a box of cake mix with half of the required ingredients on the box, using only 1 egg.
  2. Pour the batter over the crushed pineapple and brown sugar in an 8-inch square dish, including some pineapple juice.
  3. Microwave uncovered for 4 to 4 1/2 minutes.
  4. Rotate the dish and microwave for an additional 4 1/2 minutes.
  5. Let the cake rest; it may look undone but will finish cooking while resting.

Tips & Substitutions

For an extra burst of flavor, consider adding a teaspoon of vanilla extract or a pinch of cinnamon to the batter. If you don’t have crushed pineapple, you can substitute with other canned fruits like peaches or pears. Adjust the sweetness by varying the amount of brown sugar based on your preference. This recipe is flexible and works well with lemon or white cake mixes.

Serving Suggestions

Serve this delightful cake warm, topped with a scoop of vanilla ice cream or whipped cream for added indulgence. It pairs wonderfully with a refreshing Lemon-Orange Beverage for a light dessert experience. You can also enjoy it as a sweet breakfast treat alongside a cup of coffee or tea.

Storage & Reheating

Store any leftover cake in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual slices for 20-30 seconds until warmed through. If you prefer a fresh texture, consider reheating in a conventional oven at 350°F for about 10 minutes.

Frequently Asked Questions

Can I use a different type of cake mix?

Yes, you can use any flavor of cake mix such as chocolate or spice for a unique twist. Just keep in mind that the flavor of the fruits will influence the overall taste, so choose a mix that complements the pineapple.

What if my cake looks undone after microwaving?

It’s normal for the cake to appear slightly undercooked when you first take it out. Allow it to rest for a few minutes; the residual heat will finish cooking the cake, resulting in a moist and fluffy texture.

Can I make this cake vegan?

To make this cake vegan, substitute the egg with a flaxseed egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water) and ensure your cake mix is dairy-free. This will still yield a delicious and moist cake while adhering to vegan recipes.
