Step-by-Step Instructions:
1. Prepare Your Pan and Oven
Preheat your oven to 350°F (175°C). Grease and flour a 9×9 inch baking pan. This ensures your coconut lime coffee cake doesn’t stick.
2. Whisk Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set this mixture aside for now.
3. Cream Wet Ingredients
In a large bowl, cream together the softened butter and granulated sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla extract and lime zest.
4. Combine Wet and Dry
Gradually add the dry ingredients to the wet ingredients, alternating with the coconut milk. Begin and end with the dry ingredients. Mix until just combined; do not overmix.
5. Make the Topping
In a small bowl, combine the shredded coconut, granulated sugar, flour, and lime zest. Pour in the melted butter and stir until crumbly. This makes a delightful topping for your coffee cake.
6. Assemble and Bake
Pour half of the cake batter into the prepared pan. Sprinkle half of the topping mixture evenly over the batter. Add the remaining cake batter, then top with the remaining streusel. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
7. Prepare the Glaze
While the cake cools slightly, whisk together the powdered sugar and lime juice in a small bowl until smooth. If the glaze is too thick, add a few more drops of lime juice. If it’s too thin, add a little more powdered sugar.
8. Glaze and Serve
Once the cake has cooled for about 10-15 minutes, drizzle the lime glaze generously over the top. Let the glaze set for a few minutes before slicing and serving. Enjoy your homemade coconut lime coffee cake!
Variation Ideas:
- Pineapple Coconut: Add 1/2 cup finely diced pineapple to the batter for an extra tropical punch.
- Almond Extract: Swap vanilla extract for almond extract in the cake and glaze for a different flavor profile.
- Berry Swirl: Fold in 1/2 cup of fresh blueberries or raspberries into the batter before baking.
- Orange Zest: Use orange zest and juice instead of lime for a citrusy alternative.
Storage Instructions:
Store leftover coconut lime coffee cake tightly covered at room temperature for up to 3 days. For longer storage, refrigerate for up to 5 days. To refresh, you can warm individual slices in the microwave for 15-20 seconds.
Frequently Asked Questions (FAQ):

Why is my coffee cake dry?
Overmixing the batter or overbaking are common causes of dry coffee cake. Mix until just combined and watch the baking time carefully.
