Ingredients You’ll Need

One of my favorite things about this cake is that it uses everyday baking ingredients while delivering bakery-style flavor.

For the Cake

• Butter – Softened butter creates a rich, tender crumb.
• Sugar – Sweetens the cake and helps create a light texture.
• Eggs – Add structure and richness.
• Key Lime Zest – This is where most of the fresh citrus flavor comes from, so don’t skip it if possible.
• Vanilla Extract – Adds warmth and balances the tart lime.
• Key Lime Juice – Brings bright citrus flavor throughout the loaf.
• All-Purpose Flour – Gives the cake its structure.
• Salt – Enhances every flavor.
• Baking Soda – Helps the cake rise beautifully.
• Sour Cream – The secret ingredient for an incredibly moist cake.

For the Raspberry Glaze

• Softened butter
• Powdered sugar
• Heavy cream
• Fresh finely chopped raspberries

The fresh raspberries add both flavor and gorgeous color without needing any food coloring.

Easy Substitutions

• Regular limes work well if key limes aren’t available.
• Greek yogurt can replace sour cream in a pinch.
• Half-and-half can substitute for heavy cream.
• Frozen raspberries may be used after thawing and draining well.

How to Make Raspberry Glazed Key Lime Cake

1. Prepare the Pan

Preheat your oven to 350°F. Spray a 9 x 5-inch loaf pan with non-stick baking spray.

2. Cream the Butter and Sugar

Using a stand mixer or hand mixer, beat the softened butter and sugar until the mixture becomes light and fluffy. This step helps create a soft cake texture.

3. Add the Wet Ingredients

Beat in the eggs until fully combined. Mix in the key lime zest, vanilla extract, and key lime juice.

4. Combine the Dry Ingredients

In a separate bowl, whisk together the flour, salt, and baking soda.

5. Finish the Batter

Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the sour cream until the batter is smooth.

Be careful not to overmix. A gentle hand keeps the loaf tender.

6. Bake

Pour the batter into the prepared loaf pan.

Bake for about 50 minutes, or until the top is golden and a toothpick inserted into the center comes out clean.

Allow the cake to cool completely on a wire rack before glazing.

7. Make the Raspberry Glaze

Whisk together the softened butter, powdered sugar, and heavy cream until smooth. Add a little extra cream if needed for spreading consistency.

Stir in the finely chopped fresh raspberries.

Spread the glaze evenly over the completely cooled cake.

Let the glaze set for several minutes before slicing and serving.

Helpful Tips

• Room-temperature ingredients blend together much more smoothly.
• Don’t skip the zest—it provides even more lime flavor than the juice.
• Overmixing can make the loaf dense instead of soft.
• Cool the cake completely before adding the glaze, or you’ll end up with a delicious (but messy) pink puddle.
• Use fresh raspberries for the prettiest glaze and the brightest flavor.
• If your loaf starts browning too quickly, loosely cover it with foil during the last 10–15 minutes of baking.

One little trick I love is zesting the limes before juicing them. It’s much easier than trying to zest an already-squeezed lime!

Variations and Substitutions

There are lots of fun ways to make this recipe your own.

• Add white chocolate chips for extra sweetness.
• Sprinkle toasted coconut over the glaze for a tropical twist.
• Mix fresh blueberries into the batter for a berry-filled loaf.
• Use lemon instead of key lime for a different citrus flavor.
• Add chopped pecans or almonds for a little crunch.
• For an extra citrus kick, stir a little additional zest into the glaze.

If you’re baking for someone with dietary needs, a quality gluten-free 1:1 flour blend usually works well in loaf cakes like this.

Storage and Reheating

This cake stores beautifully, making it perfect for baking ahead.

Room Temperature

Store covered for up to 2 days.

Refrigerator

Keep in an airtight container for up to 5 days. The glaze stays fresh, and the cake remains wonderfully moist.

Freezer

Freeze the unglazed loaf for up to 3 months. Wrap tightly in plastic wrap followed by foil.

Reheating

This cake is best served at room temperature. If you prefer it slightly warm, microwave individual slices for about 10 seconds.

FAQs About Raspberry Glazed Key Lime Cake

Can I make this cake ahead of time?

Absolutely! In fact, the flavor develops even more after sitting overnight.

Can I use regular limes instead of key limes?

Yes. The flavor will be slightly different but still wonderfully fresh and citrusy.

Why is my cake dense?

Overmixing the batter or adding too much flour can lead to a heavier loaf. Measure carefully and mix only until combined.

Can I freeze Raspberry Glazed Key Lime Cake?

Yes. For the best results, freeze the cake before glazing and add the fresh raspberry glaze after thawing.

Can I use frozen raspberries?

Yes. Just thaw and drain them well to prevent excess moisture from thinning the glaze.
