Baking...War?

"Ann?" 
"Mmmm?" 
"What are you doing?" 
She paused, glancing over her shoulder. "Doing?" 
"With those barrels?" 
She grinned, a wicked glint in her eyes. 
"I'm just baking."
I raised a skeptical eyebrow. "With flour and....gunpowder?" 
She laughed and winked. "Yes!" 
"....you can't bake with gunpowder..." I mean, you could use it to start the fire, but why would she need a whole barrel of it? 
"I'm not just baking a cake silly." She said hefting the barrel of flour. Her grin turned devilish. "I can also bake war!!" She cackled and disappeared downstairs into the dungeon, aka her lab. 
I rubbed the side of my face. "Do I even want to know?" I muttered, glancing down at my half finished list of supplies I'd been writing down. "Yes. Yes I do." I stood up abruptly, the chair making a squeal as I shoved it back and ran down the stairs. "Ann!! You can't blow up the castle!!" I yelled.
