"Is you sure about this, 'Tia?" Luna asked.
The little filly was standing on a small table so that she could reach the counter, while Tia, being a little older and a little larger, was rapidly mixing ingredients in a large bowl with a wooden spoon. She didn't have to stand on anything to reach the counter, and kept a watchful eye on her younger sibling. Luna had a bowl in front of her as well, but was having a harder time stirring her own ingredients as the spoon kept getting stuck.
"Of course I am," Celestia said. "Mom and Dad are out for the afternoon, and I want to surprise them. They do so much for us, it's time we did something for them. Have you finished your bowl yet?"
"Uh huh," Luna said, and slid it over. Tia looked down into the bowl with slight suspicion. "There's a lot of dough in here, Luna. Are you sure you did it right?"
"I'm sure!" Luna protested. "I know how to read numbers, I can count up to a hunnred by myself!"
Celestia softened. "Alright, alright, give it here."
The large oven they were going to be using was more like a kiln than anything. A hulking monstrosity with a fire lit underneath it. Celestia took the two bowls and dumped their contents out onto the counter, mixing them together into a large lump. She started tossing it back and forth in the air with her horn.
"Lemme do it, lemme do it!" Luna begged.
"Maybe next time," Celestia said. "You've barely even started magic training."
Luna crossed her front legs defiantly.
Splitting the dough apart into even segments, Celestia placed the segments into baking pans.
"When do we get bread?" Luna asked.
"Not for a while yet," Celestia said gently. "Come on, we have to let it rise now. You want to play marbles?"
"Yeah!"
"Alright, but first we need to do your timekeeping lesson," Celestia said. "Go get the sundial."
Luna pouted. "But I don't like the sundial!"
"Luna..." Celestia warned.
"Fine..." And Luna left the room.
After a timekeeping lesson and several rounds of marbles, Celestia and Luna returned to the kitchen. Celestia gasped in shock at what she found. The bread had risen neatly, as it was supposed to, but then in a not so neatly fashion, it had CONTINUED rising. The dough had spilled over the sides of the baking pan and was rapidly covering the counter like a magically enchanted vine.
Discord, though little, stood nearby and was watching this entire process with faint amusement.
"Discord!" Celestia snapped. "What did you do?!"
"Me? Nothing," he sounded offended. "I'm just standing here... loafing around, I guess you could say."
"My bread is everywhere, its ruined!" Celestia's voice was dismayed.
"Well I wouldn't say ruined," Discord said. "But I'd say the mess is the yeast of your worries right now."
Celestia glared at him. "Discord!"
"I didn't do it, honest! Would I lie to you?"
Celestia didn't answer this, and instead looked at Luna. "Did you put the ingredients in EXACTLY like I told you?" She demanded, her horn lighting up and trying to contain the assault of rising bread.
"Well... not exactly..." Luna said quietly. "You said we were in a hurry, so I put in twice as much of everything."
"What?!" Celestia was mortified.
"But that way it'd be done twice as fast!" Luna insisted.
"Luna, it doesn't work like that! Help me!"
The two children rapidly tried to push together all the rising dough, but there was a wild amount of it.
Discord, standing off in the corner, raised his talons and an umbrella appeared within them, and snapping his claws once more resulted in a violent explosion from the counter that knocked both Luna and Celestia on their backs.
Dough and yeast was everywhere, coating the entire kitchen. The walls, the ceiling, the floor. The fire underneath the kiln had whimpered and gone out completely.
Worst of all, completely covered in muck, were Mom and Dad, standing with horrified shock in the doorway of the kitchen.
"Celestia..." Mom said with deadly malice dripping from her voice. "Explain."
Stammering, Celestia found she had temporarily lost the ability to speak. Both children pointed their hooves at Discord.
"Oh, sure, blame the draconequus," Discord complained.
