Fudgy M&M Brownies
The counter was cluttered with notes from earlier errands, a backpack rested near the chair, and someone was sorting colorful candies into small bowls nearby. Outside, the day moved slowly, but indoors there was that familiar pull toward making something sweet and simple. Baking felt less like a task and more like a way to reset the room.
There were different rhythms happening at once. One person hovered near the stove, curious about what was melting, while another leaned against the counter scrolling through messages about an upcoming classroom celebration.
The sound of candy hitting the bowl cut through the quiet, bright colors catching the light. Moments like this rarely feel organized, yet they often produce the most memorable treats. Everything moved quickly, but without pressure.
By the time the pan was pressed and topped, the kitchen had shifted again. The mess was mostly cleaned, the noise had softened, and there was time to wait while everything settled.
Cutting into shapes came later, after the surface had cooled and firmed up. It felt like the kind of dessert made for sharing casually, shaped by whoever happened to be nearby at the time.

Key Ingredients

Cooking Instructions
Step 1: Prepare the Pan
Lightly coat a 9×13 inch pan with cooking spray and set aside so the mixture releases easily once set.
Step 2: Melt the Butter
Place the butter in a large saucepan over low to medium heat. Stir until fully melted, then add vanilla extract and sea salt.
Step 3: Melt the Marshmallows
Add mini marshmallows and stir constantly until completely melted and smooth. Reduce heat if the mixture starts to darken.
Step 4: Add the Cereal
Remove the pan from heat and gently fold in the Rice Krispies cereal until evenly coated and glossy.
Step 5: Add the Candy
Fold in the M&M’s quickly, stirring just enough to distribute them without melting the candy shells.
Step 6: Press into the Pan
Transfer the mixture to the prepared pan and press evenly using a spatula or lightly greased hands. Do not press too firmly.
Step 7: Decorate
Sprinkle the top with sprinkles while the mixture is still warm so they stick.
Step 8: Set and Slice
Allow the bars to set at room temperature, then slice or cut into shapes before serving.
