Kitchen Help

How do I make the rat decorations stay in place?

Use melted white chocolate as an adhesive for the candy eyes, noses, and ears. Allow the chocolate to set completely to secure decorations firmly.

Can I substitute ingredients for dietary needs?

Yes, swap all-purpose flour with gluten-free blends and ensure candies are allergen-free for dietary preferences or restrictions.

What’s the ideal baking time to keep bites fudgy?

Bake for 18 to 20 minutes until a toothpick shows moist crumbs for a perfectly fudgy center without overbaking.

How can I customize the look beyond the rat theme?

Experiment with different colors of melted chocolate, sprinkles, or small candies to create unique decorations fitting various themes or occasions.

What's the best way to store these brownie bites?

Keep them in an airtight container at room temperature for up to three days or refrigerate to extend freshness.
