Equipment
- Large microwave-safe glass or ceramic bowl (at least 2-quart capacity with high sides)
- Whisk or spoon for stirring
- Small saucepan (for warming cream) OR microwave-safe measuring cup
- Oven mitts or heat-resistant gloves
- Measuring cups and spoons (or kitchen scale for precise measurements)
- Storage jar or airtight container
Ingredients
- 67 g granulated sugar 1/3 cup
- 20 g water 1 tablespoon + 1 teaspoon
- 30 g heavy cream, warmed 2 tablespoons
- 15 g unsalted butter, room temperature 1 tablespoon
- 1 g salt 1/4 teaspoon
- 2.5 g vanilla extract 1/2 teaspoon
Instructions
Warm the Cream
- Heat the heavy cream in a small saucepan on the stovetop or in the microwave until hot but not boiling. Set aside and keep warm. Have your room temperature butter, salt, and vanilla extract measured and ready.
Combine Sugar and Water
- Add the water to a large, clear microwave-safe glass bowl first. Slowly pour the granulated sugar into the center of the water. Do NOT stir! This prevents sugar crystals from sticking to the sides of the bowl, which can cause crystallization.
Microwave in Intervals
- Microwave on HIGH for 1 minute. Check the mixture - it should be bubbling. Continue microwaving in 30-second intervals, checking after each interval. Once you pass the 2-minute mark, switch to 15-second intervals. Stop immediately when the mixture turns honey-gold in color. Total time should be approximately 2-3 minutes depending on your microwave wattage.
Let It Rest
- Remove the bowl from the microwave using oven mitts (it will be extremely hot!). Let it sit undisturbed for about 1 minute. The caramel will continue to darken from carryover heat to a rich amber-brown color. Do not skip this step!
Add Warm Cream
- Slowly add the warm cream to the caramelized sugar, about 1 tablespoon at a time, whisking constantly. The mixture will bubble vigorously - this is normal. Continue whisking until all the cream is incorporated.
Add Butter and Flavorings
- Add the room temperature butter and whisk until completely melted and smooth. Stir in the salt and vanilla extract until well combined.
Cool and Serve
- Allow the caramel sauce to cool for a few minutes. The sauce will seem thin at first but will thicken as it cools to the perfect drizzling consistency. Use immediately or store in the refrigerator.
Notes
Use a large, clear glass or ceramic microwave-safe bowl with high sides, the caramel bubbles up significantly during cooking.
Microwave wattages vary. Watch carefully and adjust timing as needed. Pull the mixture from the microwave when it’s just honey-gold, not dark amber.
The cream must be warm before adding to prevent the caramel from seizing and hardening into clumps.
Do NOT stir the sugar and water mixture before microwaving. Let the microwave do all the dissolving work to prevent crystallization.
The caramel continues to cook and darken after removing from the microwave due to residual heat. This is why you pull it early.
If your caramel crystallizes, it likely had sugar crystals on the bowl sides. Next time, avoid stirring completely.
STORAGE INSTRUCTIONS:
Store in an airtight container or jar in the refrigerator for up to 1 week. Reheat in the microwave for 15-20 seconds to return to drizzling consistency, or place the jar in warm water until warmed through. RECIPE TIPS:
Why use a clear bowl? A clear or light-colored bowl allows you to see the color change accurately. Dark bowls make it difficult to gauge when the sugar reaches the perfect caramel color. How do I know when it’s done? The mixture should turn honey-gold in the microwave. After resting for 1 minute, it will deepen to a rich amber-brown. What if my caramel is too thin? Let it cool completely - caramel thickens significantly as it cools. If still too thin after cooling, microwave briefly to reduce further. Can I double this recipe? This recipe is optimized for the microwave at this size. Larger batches may not heat evenly. It’s better to make multiple batches. SERVING SUGGESTIONS:
Drizzle over vanilla ice cream or frozen yogurt
Dip apple slices or fresh fruit
Add to coffee or lattes for caramel flavoring
Drizzle over cakes, cupcakes, or brownies
Use as a dipping sauce for pretzels
Top pancakes or waffles
Swirl into cheesecake or brownie batter
Drizzle over popcorn for caramel corn FAQ:
Q: Can I use salted butter instead of unsalted?
A: Yes, but reduce the added salt to just a pinch to avoid over-salting. Q: Why can’t I stir the sugar and water?
A: Stirring can splash sugar crystals onto the sides of the bowl, which causes crystallization and creates a grainy texture. The microwave dissolves everything without stirring. Q: My caramel seized up when I added cream. What happened?
A: The cream was likely too cold. Always warm your cream before adding it to the hot caramelized sugar. If this happens, try gently reheating while whisking constantly. Q: Can I make this ahead of time?
A: Yes! Store in the refrigerator for up to 1 week. Reheat gently before using. Q: What if I don’t have a microwave?
A: You can make this on the stovetop using the traditional caramel method, but you’ll need a candy thermometer and constant attention. Q: Is this recipe gluten-free?
A: Yes, all ingredients are naturally gluten-free.
